1. Why do Wall Ties fail?

In older properties, wall ties were typically made of galvanised steel. Over time, the protective zinc coating breaks down, allowing the steel to rust/corrode. As iron turns to rust (“oxidises”), it expands to several times its original thickness.

The Telltale Signs:

• Horizontal Cracking: This is the most common symptom. As the ties expand within the mortar joint, they physically lift the brickwork, causing horizontal cracks to appear, usually every 3-4 courses of bricks in the same courses where the wall ties were installed. This is known as “oxide jacking”. This is more noticeable at the top of a gable end wall where the weight of the brickwork is lighter.
• Roof Movement: A less obvious sign is the lifting of roof tiles on the ridge. If the brickwork has lifted significantly due to expansion, it can push the roof structure upwards, leading to a “lip” at the edge of the roof.
• Bulging Walls: In extreme cases, if the ties have snapped or thinned through corrosion, the outer leaf of the wall can pull away from the inner leaf, leading to a visible bulge.

2. The Survey Process: Peering into the Cavity

You cannot accurately diagnose wall tie failure from the outside alone. A professional surveyor will carry out an intrusive (but non-destructive) inspection.

The Borescope Inspection: The surveyor drills a small, discreet hole into the mortar joint. They then insert a borescope (also known as an endoscope) – essentially a high-definition camera on a flexible cable – to look inside the cavity.

A Note on Insulation: If your home has cavity wall insulation (like polystyrene beads), this process can be a bit of a headache. The beads tend to pour out of the hole or swarm the camera lens, blocking sightlines. It requires a bit more patience and effort to clear a view, but for a skilled surveyor it is still perfectly doable.

The survey allows the surveyor to check:

1. The physical condition and corrosion level of the existing ties.
2. The “density” (quantity per area) of the ties. Builders occasionally “forgot” to install enough of them… and even sometimes don’t install any!
3. The presence of debris or “snots” (mortar droppings) that might be bridging the cavity and causing damp.

Target Fixings’ technical team, and Target Structural installation teams are trained to carry out wall tie surveys, and can write a report on the condition of wall ties. If you are concerned, get in touch with our team and we can guide you through the process and provide you with a fully costed quote.

You are also more than welcome – in fact encouraged! – to have a look inside the cavity yourself.

3. The Solution: Remedial Wall Ties

If the survey confirms the ties are failing, don’t panic. This isn’t like subsidence which is often out of your control and linked to ground movement that can be unpredictable even after a repair is carried out. Wall tie replacement is an upgrade to your property’s structural integrity, and insurance is very unlikely to be affected.

The Replacement Process: We typically use Helical Wall Ties (such as our Retro Flex of Dri Flex systems). These are made from stainless steel and are designed to be retrofitted through the outer leaf of the brickwork.

• Installation: With Retro Flex, holes are drilled through the outer leaf and the tie is hammer driven through the hole, creating a mechanical connection in the inner leaf. Polyester resin, or cementitious grout is used to chemically bond it to the outer leaf. It is also possible to hammer the tie through both leaves, using a Dri Flex.
• The Old Ties: It isn’t enough to just add new ties; the old, corroding ones must also be dealt with. They are either physically removed or “isolated” (covered with a foam sleeve or similar) to prevent further expansion from damaging the masonry.
• Accessibility: Usually, this is all done from the outside. While it theoretically can be done from the inside if the exterior is inaccessible, it results in a lot of holes… hardly ideal if you’ve just finished decorating!

4. Materials and Longevity

Modern remedial ties are a “fit and forget” solution because they are manufactured from stainless steel, providing a vast upgrade on corrosion resistance from galvanised steel.

• Standard Grade: Grade 304 stainless steel is the industry standard for most inland properties.
• Coastal Grade: If you live near the coast, we always recommend Grade 316 stainless steel. This has a much higher resistance to the “salt air” and sea water breezes that can accelerate corrosion even in modern materials.

Target Fixings only produces helical wall ties in stainless steel.

Final Thoughts

Wall tie replacement is a standard, routine fix that shouldn’t impact your ability to get insurance – in fact, it’s often a requirement of the surveyor to ensure the building remains insurable.

If you’re concerned about your property, we are always happy to quote for a survey. We’ll even let you have a look through the borescope yourself so you can see exactly what’s going on inside your walls!

The post What is Wall Tie Failure? Signs, Surveys, and How to Fix It appeared first on Target Fixings.

A February 2026 announcement from Stroma Building Control has sent shockwaves through the industry. In it, Stroma declared that they would “no longer accept applications for foundation designs that propose the use of metal ground screws”. A second technical update in April 2026 clarified the position, permitting ground screws only under certain rigorous criteria. By doing this, Stroma has addressed a long-standing issue – one we wholeheartedly agree with – regarding piles that are not adequately tested on site.

Heli Pile is not affected by this decision. While the confusion is understandable due to our helical profile, the technical reality is fundamentally different: Heli Pile is an impact-driven pile, not a screw pile or a ground screw. Further, there is no guesswork – our system is always fully tested on site in-situ.
 
Stroma’s Concern
Stroma’s update targets a specific failure in the ground screw market. Many ground screw installers rely on a correlation between installation torque and hypothetical axial capacity. Stroma has rightly noted that “site torque testing in itself is not a sufficient demonstration of adequacy”. These systems often rely on “lab” design tests that fail to reflect actual site conditions.

Why Heli Pile Is Unaffected
Heli Pile is not screwed into the ground under torque. It is a hammer-driven piling system.

• Installation: Driven via a high-frequency pneumatic hammer (900–1700 bpm).
• Mechanism: While it has a helical profile, it turns as it is driven, rather than driving as it is turned. This creates a secure mechanical interlock and compresses the surrounding substrate, increasing end-bearing pressure.
• Verification: We do not guess capacity. Heli Pile capacity is tested on-site, in situ.

How We Exceed Stroma’s Requirements
Stroma’s April update demands axial testing post-installation. For Heli Pile, this is our standard operating procedure.

If you have specified Heli Pile, your project is not under threat. We provide the evidence that Stroma is looking for because our system was built on the principle of verification, not estimation.

Don’t let the ground screw ban stall your project. Switch to a system that provides structural certainty.

One of the most common concerns we come across on Reddit housing forums are stubborn cracks that keep coming back. You fill it, sand it, and paint over it, and it reappears six months later.

If it keeps reappearing, it must be structural, right?

No, not necessarily. It could be cyclical clay swell/shrinkage, the structure swaying in the wind, or it could even be something as simple as somebody slamming a door. If the crack reappears after closing, it indicates the structure is under a variable load, and the structures/finishes are too rigid/brittle to accommodate the strain without cracking.

Many masonry cracks (particularly in the UK) are seasonal. Your house lives in a dynamic environment. It sits on top of ground that breathes, experiences storms that buffet it, while rain and snow insist on trying to wash it away.

Meanwhile, many elements in your house are not flexible. Your house is likely to be constructed or faced with masonry that is designed for rigidity. The downside of this is that, when the environment causes variable loads (i.e. pushes and pulls your house), this will cause your home to crack if it moves too far.

So, it can be safely filled?

In most cases, yes. But… there’s a catch.

If you fill a crack while it’s at its widest point (summer), you’ve essentially shoved a wedge into the wall. When the masonry tries to close back up in winter, it hits that filler. If the filler is hard, this does one of two things:

Or, if the filler is softer than the wall it simply crushes and the cracking is visible again.

This continuous cycle of chasing seasonal cracks is why we quite often recommend scheurnaden with helical bar (Bar Flex) to BF-01.

Isn’t crack stitching an admission of a structural problem?

Yes, and no. There are very, very few (zero?!) houses that have no structural quirks. That’s part of the fun of being a homeowner, right? But, of course, some structural problems are worse than others.

When it comes to seasonal cracking, this is primarily an aesthetic concern. You can’t stop the weather and you can’t stop the ground moving, so you can either put up with it, continue to fill the same crack every year, or stitch the crack.

By using a helical bar like our Bar Flex, you aren’t just “plugging the hole”, you’re reinforcing the structure. Bar Flex is a flexible reinforcement bar, and it both allows the masonry to move slightly, as well as restraining that movement.

In addition, it dissipates the movement along the length of the bar, so cracking is greatly – or completely – reduced.

Is crack stitching optional?

In a lot of cases, yes – but only in the same way that painting your walls is optional. If continuous cracking annoys you, then crack stitching greatly reduces the visual effects of these unavoidable movements while providing greater resilience. If it doesn’t bother you… then leave it!

Can crack stitching solve structural problems?

Usually, no. Not on its own, anyway. In full structural specifications, we often specify some crack stitching to prevent the reappearance of cracks but, on its own, it’s unlikely to resolve more severe structural problems.

The post What is Crack Stitching anyway? appeared first on Target Fixings.

If you work in the built environment—or if you simply own a property—you know that structural issues can be a source of immense stress and confusion. For homeowners, the need for wall crack repair represents a potential financial black hole. For structural engineers, architects, and surveyors, the challenge often lies in finding specific, reliable technical data on metselwerkwapening without having to wade through endless sales brochures.

At Doelbevestigingen, we believe that the best way to solve structural problems is through clear communication and shared expertise. That is why we are excited to announce the launch of our brand-new community on Reddit: r/TargetFixings.

Why Reddit? Why Now?

We know that the construction industry is changing. The days of relying solely on phone calls and physical manuals are fading. Today, people want fast, accessible, and peer-reviewed information. Whether you are scrolling on your lunch break at a building site or researching late at night after spotting a defect in your living room, you need a hub where you can get honest structural repair advice.

We chose Reddit because it is the internet’s best engine for community discussion. It allows for high-quality photo uploads (essential for diagnosing defects), threaded conversations that keep technical debates organized, and a level of transparency that standard social media lacks.

A Hub for Every Stakeholder

We have designed r/TargetFixings to be a “broad church” for anyone interacting with masonry structures. Here is how we envision the community serving you:

For the Homeowner and Property Developer

Finding a structural defect is scary. The jargon—verzakkingsproblemen, zijdelingse steun, delamination—can be overwhelming. When you are facing issues like reparatie verzakkingen, you need clarity, not confusion.

Our subreddit is a safe space to post photos of your concerns. While an online forum can never replace a physical site survey, our experts can provide that crucial “first look.” We can tell you if a fissure looks like simple thermal movement or if it indicates deeper movement requiring professional intervention. We can guide you on what to ask your surveyor and demystify the process of wall crack repair.

For Structural Engineers and Architects

You need specs, load capacities, and honest data on material longevity. On r/TargetFixings, we can get into the weeds of technical detail regarding metselwerkwapening.

Want to discuss the tensile strength of our Bar Flex system? Need to know the specific installation torque for Helipalen in different soil types? This is the place for peer-to-peer technical exchange. It is also a space to discuss the merits of modern repair techniques versus traditional “rip out and replace” methods, fostering a more sustainable approach to engineering.

For Building Surveyors

You are on the front lines, diagnosing defects daily. We want this community to be a repository of case studies. We will be sharing “before and after” deep dives from our own manufacturing and installation projects. You will see exactly how we tackle common issues like lintel failure and how our bespoke manufacturing process allows us to tackle unique, listed, and heritage buildings.

The Target Fixings Advantage: From Factory to Foundation

What makes r/TargetFixings different from a generic DIY forum? It is backed by the unique expertise of Target Fixings.

We are rare in this industry because we own the entire lifecycle of the product. We don’t just buy boxes of wall ties and sell them on. We manufacture them. We sell them. And, critically, our specialist teams install them.

This means the structural repair advice you get on the subreddit isn’t theoretical; it is born from decades of hands-on experience. When we discuss lintel failure of reparatie verzakkingen, we are drawing on thousands of successful projects.

Join the Conversation

We are building this community to be a helpful, noise-free zone for structural integrity. Whether you want to show off a neat repair job, ask a burning question about metselwerkwapening, or just lurk and learn about the physics of falling buildings, you are welcome.

Come say hello, introduce yourself, and let’s start fixing things together.

Arkadiusz Pękacz – Regional Director, Warsaw Poland

Masonry Reinforcement Materials for Historic Repair

The architectural landscape of Warsaw is a profound blend of resilience and innovation. Among its most storied sites is the Łukasiewicz Research Network – Institute of Aviation, an institution that has stood as a beacon of Polish engineering since 1926. However, maintaining the structural integrity of a century-old masonry building requires more than just traditional repair methods—it demands surgical precision and a deep respect for historical fabric.

We are proud to announce that our Warsaw team has successfully completed the structural reinforcement of this landmark office and laboratory building. Working as part of a comprehensive “Renovation and Reconstruction” project, we delivered a technical solution that satisfied the rigorous demands of both modern engineering standards and heritage conservation.

The Challenge: Balancing Strength and Aesthetics

For structural engineers and architects, the primary challenge of the Institute of Aviation project was the building’s status. As a site listed in the register of historic monuments and under the protection of the Monuments Conservator, any intervention had to be virtually invisible. Traditional “patch and repair” or heavy external bracing were non-viable options, as they would fundamentally alter the historic façade.

The masonry structure required a system capable of redistributing loads and stabilizing cracks without the need for invasive rebuilding. This is where masonry reinforcement materials specifically designed for “stitching” become indispensable.

The Solution: Bar Flex Masonry Stitching

After a thorough assessment by the Project Designer and the Conservator, our Bar Flex masonry stitching technology was selected as the only approved method for the reinforcement. The scope of work involved the installation of 300 metres of 6 mm Bar Flex stainless steel helical bar.

The technical superiority of the Bar Flex system lies in its design and application:

• Ductile Strength: The helical profile of the rods allows for a mechanical bond with Target Fixings Bond Flex grout that is far superior to standard rebar. It provides high tensile strength while allowing for natural thermal and moisture movement within the brickwork.

• Corrosion Resistance: Using high-grade stainless steel ensures that the reinforcement will not oxidize or cause “rust-bursting,” a common failure point in historic buildings where mild steel was used previously.

• Non-Invasive Installation: The Bar Flex is installed directly into the horizontal masonry joints (the bed joints). By raking out the mortar, inserting the Bar Flex, and repointing with a compatible lime or Bond Flex cementitious grout, the structural “stitch” is hidden entirely within the wall.

Why Structural Professionals Choose Bar Flex

For the building surveyors and property owners involved in the Institute of Aviation project, the primary concern was long-term stability without visual compromise. The Bar Flex masonry stitching system acts like a hidden skeleton. It effectively bridges cracks and distributes masonry loads across the wall, preventing further separation while remaining completely hidden from view once the joints are repointed.

The successful completion of this project proves that Doelbevestigingen provides the optimal technical solution for brick masonry structures. Whether dealing with 1920s aviation hubs or contemporary residential blocks, the ability to reinforce a structure without a visible footprint is a game-changer for the Warsaw construction market.

Commitment to Heritage and Engineering Excellence

This project at the Institute of Aviation is a testament to why we are leaders in the field of masonry reinforcement materials. We ensured that a piece of Warsaw’s history is structurally sound for the next century.

For architects and engineers looking to specify a system that offers predictable performance in historic contexts, our spiral reinforcement remains the gold standard. We don’t just fix buildings; we preserve the aesthetic integrity of our city’s skyline.

The post The Best Masonry Reinforcement Materials for Historic Repair appeared first on Target Fixings.

Choosing the best Masonry Reinforcement Systems can be a large choice of options. Building maintenance often reveals hidden structural secrets. While many homeowners focus on aesthetic upgrades, the integrity of the building’s skeleton is what truly matters for long-term safety. Recently, our team was called to a project in Oxfordshire where a routine inspection uncovered a significant structural separation.

The Oxfordshire Challenge: Identifying Structural Instability

While a local contractor was performing unrelated works on a beautiful Oxfordshire property, they noticed a concerning symptom: the front elevation, constructed of traditional stone and brick, had begun to move away from the timber-frame based left elevation. This type of separation is a classic sign that the building’s original binding methods are failing, requiring immediate Structural Masonry Strengthening.

Left unaddressed, this gap could have led to moisture ingress, thermal loss, and eventual structural collapse. The homeowner was understandably worried about the potential for unsightly external plates or intrusive internal beams that traditional “S” or “X” ties often require.

Why Traditional Methods Weren’t the Answer

In the past, stabilising a bowing or separating wall meant bolting a large, visible metal plate to the exterior of the house and running a thick beam through the living space to provide tension. For a property in the scenic Oxfordshire countryside, this wasn’t an option. We needed a solution that offered the strength of industrial engineering with the subtlety of a conservation-grade repair.

As a leading Franchise Business specialising in these niche repairs, we recommended our proprietary Masonry Reinforcement Systems. Specifically, we opted for the Bow Flex Type 2 system.

The Science of the Bow Flex Type 2 System

- Bow Flex Type 2 is a specialised helical-shaped reinforcement designed to provide a “hidden fix.” Unlike standard wall ties, this system uses the existing structural members of the house to provide stability.

Technical Specifications:

• Material: Bow Flex 12mm high-grade Stainless Steel Wall Ties.

• Design: Threaded bar that acts as a robust connection and can act as an internal “noggin.”

• Function: Pins the masonry elevation directly to the internal timber floor joists.

The Installation Process: Method BO-02

Once the plan was signed off, our technicians returned to the site to execute Method BO-02. Precision is the cornerstone of effective Masonry Crack Repair Solutions.

1. Surveying and Marking: We meticulously marked the wall to ensure no electrical services or plumbing lines were disturbed.

2. Scaffolding: Because the pinning was required across both storeys of the property, professional scaffolding was erected to ensure a safe and level workspace.

3. Drilling and Cleaning: A clearance hole was drilled through the external masonry and deep into the center of the internal joist. We then thoroughly cleaned the hole of all debris to ensure maximum adhesion.

4. Pinning: The Bow Flex Type 2 was driven through the masonry. While this system can often span three joists, the unique visibility constraints of this Oxfordshire timber frame led us to a cautious, expert-led approach of pinning to the second joist for guaranteed security.

5. Bonding: To lock the system in place, the remaining hole was injected with Target Fixings Bond Flex, a high-strength bonding agent that ensures the stainless steel becomes a permanent part of the building’s fabric.

An Invisible Finish for Oxfordshire Homes

The primary benefit of our Masonry Reinforcement Systems is the aesthetic result. Once the installation was complete, the small entry points were filled and prepped for rendering. When the wall is re-rendered and painted, there will be absolutely no visual evidence that a major structural repair took place.

This project perfectly illustrates how modern technology can preserve the charm of traditional Oxfordshire architecture while providing the necessary Structural Masonry Strengthening to keep a home safe for generations.

Mieszkając na terenach aktywnych górniczo lub pogórniczych, widok pęknięć na elewacji domu często budzi uzasadniony lęk. Czy to tylko “praca budynku”, czy może poważne naruszenie konstrukcji wywołane ruchem górotworu? Z naszego wieloletniego doświadczenia w Target Fixings wynika, że szkody górnicze wymagają zupełnie innego podejścia niż standardowe remonty. Tradycyjne metody, takie jak “zamurowanie dziury” czy wylanie tony betonu, w tym przypadku często okazują się nieskuteczne, a wręcz szkodliwe.

W tym artykule wyjaśnimy, jak precyzyjnie diagnozować pęknięcia pochodzenia górniczego i jak trwale zabezpieczyć dom, wykorzystując nowoczesne technologie inżynieryjne, które stosujemy na co dzień – bez konieczności rozkopywania całego ogrodu.

Jak odróżnić szkody górnicze od zwykłego osiadania?

Nie każde pęknięcie oznacza, że dom się zawali. Jednak uszkodzenia spowodowane działalnością górniczą mają swoją specyficzną “sygnaturę”. Ruchy górotworu powodują nierównomierne osiadanie gruntu pod fundamentami, co generuje ogromne siły rozciągające w murach.

Na co zwracamy uwagę podczas pierwszych oględzin?

• Pęknięcia schodkowe : To najbardziej charakterystyczny objaw. Rysa biegnie zygzakiem po spoinach (fugach), przypominając schody. Oznacza to, że jeden fragment budynku obniża się względem drugiego.

• Efekt “Choinki” : Pęknięcia rozchodzące się od narożników okien i drzwi.

• Problemy ze stolarką: Jeśli nagle drzwi lub okna przestają się domykać, a na łączeniu wykuszów ze ścianą główną pojawiają się pionowe szczeliny, to sygnał alarmowy świadczący o utracie podparcia.

Zamiast panikować, należy przeprowadzić chłodną analizę. Ignorowanie tych sygnałów może prowadzić do awarii nadproży , gdzie mur nad oknem traci oparcie i zaczyna “wisieć” w powietrzu.

Dlaczego beton nie jest rozwiązaniem na szkody górnicze?

Częstym błędem inwestorów jest próba naprawy szkód górniczych poprzez wylewanie masywnych ław betonowych (tzw. underpinning tradycyjny). Dlaczego w Target Fixings odradzamy to rozwiązanie?

Tereny górnicze są dynamiczne. Grunt może pracować latami. Beton jest sztywny i kruchy. Jeśli wylejemy sztywny beton pod fragment domu, a ziemia znów się poruszy, beton pęknie lub spowoduje pęknięcie w innym, słabszym miejscu konstrukcji. Co więcej, tradycyjne podbijanie fundamentów jest niezwykle inwazyjne, niszczy ogród i często koliduje z korzeniami drzew, co może rodzić problemy prawne.

Nasze podejście opiera się na inżynierii elastyczności. Stosujemy systemy, które “współpracują” z murem, a nie z nim walczą.

Stabilizacja fundamentów systemem Heli-Pile

Jeśli diagnoza wykaże, że grunt pod budynkiem stracił nośność (np. w wyniku powstania pustek pogórniczych lub rozluźnienia gruntu), pierwszym krokiem jest ustabilizowanie fundamentu. Tutaj wkracza technologia Heli-Pile.

To nasz opatentowany system mikropali wykonanych ze stopu aluminium, które są wkręcane w grunt aż do osiągnięcia stabilnej warstwy.

Dlaczego Heli-Pile jest idealne na szkody górnicze?

1. Działa dwukierunkowo: Mikropale te przenoszą obciążenia na ściskanie (trzymają ciężar domu), ale także na rozciąganie. To kluczowe przy szkodach górniczych, gdzie grunt może “wypychać” budynek lub go ciągnąć w dół.

2. Bezinwazyjność : Instalacja odbywa się przy użyciu lekkiego sprzętu, bez ciężkich wykopów. Idealnie sprawdza się w trudno dostępnych miejscach.

3. Ochrona ekosystemu: Dzięki małej średnicy (60 mm lub 100 mm), pale omijają korzenie drzew, co pozwala na pracę w strefach ochrony przyrody .

    

“Zszywanie” ścian systemem Bar Flex

Gdy fundament jest już stabilny, musimy przywrócić integralność spękanym murom. Nie wystarczy zaszpachlować pęknięcia – siły, które je rozerwały, wciąż mogą działać. Stosujemy technikę znaną jako Scheurnaden (zszywanie pęknięć) przy użyciu systemu Bar Flex.

Jak to działa?

Bar Flex to nierdzewne pręty helikalne (skręcone jak śruba), które montujemy w spoinach muru.

1. Wycina się fragment zaprawy w poprzek pęknięcia.

2. Aplikuje się naszą specjalistyczną zaprawę Bond Flex XL.

3. Wtapia się pręt Bar Flex.

4. Spoinę uzupełnia się tak, by naprawa była niewidoczna.

Kluczem do sukcesu jest konstrukcja pręta. Posiada on rdzeń i specjalne “płetwy”, co podwaja jego wytrzymałość na rozciąganie. Działa on jak potężna sprężyna – spina mur w całość, ale pozwala na minimalne ruchy termiczne i strukturalne. Dzięki temu, przy kolejnych wstrząsach górniczych, mur ma zdolność do absorpcji naprężeń, zamiast pękać ponownie.

Porównanie metod naprawy: Tradycja vs. Target Fixings

Aby ułatwić podjęcie decyzji, przygotowaliśmy zestawienie, które pokazuje różnice między standardowym podejściem budowlanym a naszymi technologiami strukturalnymi.

Kiedy potrzebne jest wzmocnienie nadproży?

Szkody górnicze często ujawniają słabości dawnych konstrukcji, np. brak nadproży w oknach (tzw. okna nośne w starym budownictwie). Gdy grunt osiada, cegły nad oknem opadają, blokując ramy okienne.

W takich sytuacjach, zamiast wykuwać dziurę w ścianie i montować stalową belkę (co robi ogromny bałagan), tworzymy belkę w murze . Wykorzystujemy dwie równoległe warstwy prętów Bar Flex osadzonych w zaprawie Bond Flex XL powyżej otworu okiennego. Tworzy to kompozytową belkę z istniejących cegieł, która jest w stanie przenieść obciążenia, nie naruszając historycznego wyglądu elewacji.

Proces naprawy z Target Fixings – “Wszystko pod jednym dachem”

Naszym wyróżnikiem jest model działania “All under one roof”.Oznacza to, że nie musisz szukać osobno inżyniera, dostawcy materiałów i ekipy budowlanej.

1. Konsultacja i diagnoza: Nasi eksperci oceniają pęknięcia i wykonują niezbędne pomiary.

2. Projekt inżynierski: Dobieramy średnicę pali (60/100 mm) oraz rozstaw prętów Bar Flex (4.5 mm – 10 mm)  idealnie do obciążeń Twojego budynku.

3. Własna produkcja: Korzystamy z systemów, które sami produkujemy i kontrolujemy ich jakość²⁴.

4. Montaż: Nasi wyszkoleni specjaliści wykonują naprawę szybko i czysto.

5. Gwarancja: Oferujemy rozwiązania dedykowane trwałym naprawom.

Nie czekaj, aż pęknięcie stanie się awarią

Pęknięcia spowodowane szkodami górniczymi rzadko “zatrzymują się same”. Zazwyczaj postępują, prowadząc do dekompresji muru i utraty stabilności całego domu. Wczesna interwencja przy użyciu systemów Systemy wzmacniania murów pozwala zaoszczędzić ogromne kwoty w porównaniu do kapitalnego remontu po katastrofie budowlanej.

Nasze rozwiązania są nie tylko skuteczne inżynieryjnie, ale też szanują Twój dom i ogród. Działamy w myśl zasady “minimum disruption” – minimalnych zakłóceń dla domowników.

The Root of the Problem: Heli Pile Foundation near Tree Roots

In the world of UK Construction, few challenges are as persistent, or as frustrating, as designing a new structure’s foundation near mature trees. For Structural Engineers, Building Surveyors, and Architects, the goal is simple: ensure stability. For Property Developers en Huiseigenaren, the objective is to build without destroying a valuable landscape asset. When a new garage, extension, or garden room is planned, the traditional approach dictates a concrete trench foundation. But what happens when that trench inevitably intersects with a mature tree’s root system?

Digging trenches near trees, especially those protected by a Tree Preservation Order (TPO), is fraught with risk. Deep excavations can sever major structural roots, destabilizing the tree and potentially leading to its demise. Furthermore, roots extract moisture from the soil, causing volumetric changes that lead to soil shrinkage and settlement, or, conversely, soil heave if the roots are removed. This dynamic environment is a nightmare for rigid concrete foundations. The conflict between the need for a stable foundation and the necessity of root conservation requires a non-traditional, non-invasive solution.

Foundation for a New Garage

We, at Target Structural Chiltern, a licensed installer of the innovative Doelbevestigingen product range, were recently approached with just such a dilemma. The main contractor working on a residential project had raised serious concerns to their client’s Structural Engineer regarding a significant tree located in the immediate vicinity of a proposed new garage. The concern was clear: traditional foundations would almost certainly have a negative, perhaps catastrophic, impact on the tree, and the tree’s roots would inevitably pose a threat to the foundation’s long-term stability.

Following careful deliberation and review of the soil conditions and tree proximity, a piled raft solution was meticulously designed. This design specified the utilisation of our Doelbevestigingen Helipalen to provide the essential structural support for the new building, while also offering crucial resistance against potential soil heave—a key advantage when building on soil prone to moisture fluctuation near large vegetation.

Heli Pile Foundation Near Tree Roots: The Non-Invasive Solution

The reason the Target Fixings Heli Pile system was the favoured solution in this sensitive environment lies in its unique engineering. Unlike traditional piles, Helipalen work effectively in both tension and compression due to their distinctive helical shape. The shape acts as a permanent anchor in the ground, providing exceptional uplift resistance, which is vital for counteracting the expansive force of soil heave that can occur when tree roots are disturbed or removed.

Critically, the installation process for a Heli Pile foundation near tree roots is fundamentally different from traditional methods, making it the ideal non-invasive foundation for tree roots. To ensure we avoid damaging major root structures, we employ a highly sensitive, low-impact process of establishing a passage through the ground before the Heli Pile itself is installed.

This involves what we call ‘spiking’ the ground: driving a sacrificial, 40mm diameter nylon cone into the soil. This cone creates a precisely sized pilot hole that the Heli Pile can then follow. This method allows us to gently push past and around the tree roots without causing the deep, wide-scale disruption associated with trenching or boring. This is a game-changer for working near trees, offering a genuine TPO Alternative to standard disruptive foundations.

Low Impact Installation and Structural Integration

The installation equipment itself is also deliberately lightweight. Our machines and Heli Piles are carried to the site by hand, meaning the load exerted upon the ground during the entire installation process is limited to simple foot traffic. This dramatically reduces the risk of root compression or surface damage, demonstrating our commitment to conservation alongside construction excellence.

The installation on the garage project proceeded smoothly and exactly as scheduled. Once installed, the piles were rigorously tested in tension to ensure they achieved the required load specifications—a necessary step for guaranteeing the long-term integrity of the structure above.

The specification required the piles to be perfectly embedded within the proposed concrete slab for a robust connection. To enhance the connection and increase punching shear resistance, a steel plate was fixed to the top of each pile. Our team meticulously levelled all the piles to a datum provided by the main contractor, ensuring an equal and consistent embedment across the entire footprint of the proposed raft slab. This precision is key to ensuring the load is distributed evenly across the new structure.

Once our work was complete, we removed all our lightweight equipment, leaving the site tidy and ready for the next phase. The slab reinforcement can now be installed, and the concrete will be cast, encasing both the pile heads and the steel mesh. This harmonious combination provides a robust and ‘neat’ solution, ready to bear the weight of the new garage, safe in the knowledge that both the structure and the surrounding natural environment have been respected.

If you are a Structural Engineer facing a complex foundation challenge, a Property Developer looking for an efficient alternative to concrete foundations near tree roots, or a Homeowner hoping to build without felling a cherished tree, the Target Fixings Heli Pile system, installed by Target Structural Chiltern, is the advanced, non-disruptive solution you need.

Historic Preservation

Poland is a nation defined by its incredible architectural legacy. From medieval town squares to grand interwar landmarks, these buildings are more than just structures—they are tangible pieces of our history. For professionals dedicated to preserving this heritage, every project presents a unique challenge: how do we ensure a building’s stability for the next century without erasing the story of the last?

Our Polish branch, backed by decades of expertise from our UK head office, specializes in answering this exact question. We believe that modern engineering and Historic conservation must work hand-in-hand. We were recently honored to collaborate with APP PROJEKT on vital structural repairs at the beloved Apollo Cinema in Poznań, a perfect example of modern Masonry Reinforcement being used to secure an architectural icon.

The Weight of History: Why Traditional Repairs Were not an Option

The Apollo Cinema, located in the vibrant heart of Poznań, holds nearly two centuries of history. It began its life in 1846 as part of a bustling shopping arcade before being formally established as a cinema after World War I, eventually becoming the city’s largest movie house in the interwar period. Even after a beautiful Art Deco-inspired renovation in 2005, the structure remains a testament to enduring Polish culture.

However, time and continuous use take their toll. Like all older masonry buildings, the Apollo’s original brick walls began to exhibit signs of movement. Structural engineers identified significant stepped and vertical cracks in the unreinforced brickwork. These were not cosmetic issues; they were clear indications of structural stress caused by long-term differential settlement and environmental factors.

For a building with such deep cultural significance and a history of continuous operation, the remediation strategy had to be non-negotiable on two points: it had to be permanent, and it had to be non-destructive. Traditional approaches, which often involve large-scale demolition and rebuilding of wall sections, were deemed too invasive, too disruptive to the cinema’s operations, and fundamentally counter to the principles of Historic Preservation. The need was clear: a sophisticated, localised, and concealed method for Building conservation that could stabilise the walls and redistribute structural loads without affecting the building’s cherished aesthetics.

The Modern Answer: Precision Structural Stitching

In partnership with the structural design team, we proposed using our proprietary Bar Flex stainless steel helical bar system. This solution is engineered specifically for non-invasive structural repair and is a champion of Historic conservation principles. Rather than replacing the cracked masonry, we proposed integrating high-tensile reinforcement directly into the existing mortar lines.

The solution focused on three key engineering benefits:

1. Tensile Strength Where It’s Needed: Masonry is incredibly strong in compression but weak in tension. Cracking occurs when the brickwork is pulled apart. Our 6mm Bar Flex provide immense tensile strength, effectively acting as internal tendons to hold the damaged masonry together.
2. Structural Stitching: The objective was to structurally ‘stitch’ the separated sections of the brickwork, transforming discontinuous, cracked panels back into cohesive, load-bearing units. This process allows the wall to once again act as a single, structurally sound element, spanning and bridging the areas of weakness.
3. Invisible and Permanent: By embedding the Bar Flex into the existing mortar beds with a specialised grout manufactured by Target Fixings Bond Flex, the repair is completely hidden upon completion. The result is a permanent stabilisation that preserves every millimetre of the historic brick face—a vital requirement for sensitive heritage projects.

This high-performance Masonry Reinforcement methodology provided APP PROJEKT with a durable, certified, and aesthetically sympathetic solution, offering a low-impact and highly cost-effective alternative to mass replacement.

From Theory to Reality: The Skill of the Polish Contractor Team

The implementation phase required not just quality materials, but skilled hands. The installation was managed by my specialist Polish Contractor team Target Structural Poland, whose expertise is honed in handling the unique challenges of historical European architecture. The success of the Apollo Cinema project depended entirely on their precision and dedication.

The process unfolded systematically:

1. Preparation: Mortar beds were carefully raked out to a precise depth, extending a full 500mm beyond the extent of the visible cracking to ensure comprehensive load redistribution.
2. Grout Injection: Channels were meticulously cleared and prepared to receive a specialised thixotropic, non-shrink cementitious grout Bond Flex. The thixotropic property of the grout is essential; it flows readily into every microscopic void yet holds its shape, ensuring the Bar Flex is perfectly encapsulated.
3. Bar Flex Placement: Nearly 100 metres of the 6mm Bar Flex reinforcement were carefully pressed into the wet grout. The helical profile is essential here, as it maximises the mechanical key between the Bar Flex and the Bond Flex, ensuring maximum load transfer capacity.

The entire process was executed with minimal noise and dust, allowing the cinema to continue its vital cultural function with maximum efficiency. Once the Bond Flex cured, the joints were re-pointed to match the surrounding historic brickwork, making the structural intervention completely invisible. This project is a testament to the skill and dedication of my Polish Contractor teams who execute these complex Building conservation strategies every day.

We are proud to champion solutions that not only respect the past but guarantee the structural security of Polish landmarks for the future.

BFA Annual Conference 2025

Last week, the Target Fixings team—Director Edward Hall QFP, Contractor Account Manager Nevyn Fraser, and myself—had the distinct privilege of attending the BFA Annual Conference 2025 and Franchise Awards, held at the prestigious Telford International Centre.

As long-standing and dedicated members of the British Franchise Association (BFA), this annual pilgrimage is essential. We attend not just to catch up on the latest happenings in the franchising community, but to critically absorb the newest strategies, trends, and legal updates. It’s an invaluable opportunity to benchmark our growth model against the best in the UK. This year’s event, expertly sponsored by industry leaders Citation en Constant Contact, provided incredible, actionable insights, which only further cemented our conviction: a Target Structural Franchise represents one of the most robust and compelling UK franchise opportunities available today.

The day began in the main foyer, a bustling hub where we reconnected with familiar faces—people we’ve collaborated with in BFA seminars throughout the year—and met new ones. The energy was palpable, setting the stage for a highly informative day. Prior to the conference, attendees select breakout sessions tailored to their roles, ensuring everyone gains the maximum personal benefit.

Here are the 3 Key Reasons we took away from the conference that prove the fundamental strength and future potential of our specialized Masonry reinforcement franchise UK model:

1. Data-Driven Systems Mean Guaranteed Improvement and Efficiency

The conference officially commenced with a sharp focus on the revolutionary power of Data. This theme was powerfully illustrated by CEO Pip Wilkins, who shared a fascinating case study involving a track day. Using only the raw data recorded from the personal race car of Theo Millward, Director of Swimtime, and absolutely no verbal coaching, they successfully analyzed Pip’s performance. The result? They achieved a stunning 14-second improvement in her lap time across the course of the day! The visual evidence and tangible success proved the point: data is paramount.

The Franchise Takeaway: A genuinely successful franchise doesn’t operate on guesswork; it operates on proven, data-driven systems. When you decide to buy a construction franchise UK like ours, you aren’t starting from scratch. You are immediately stepping into a business model where the best practices for installing our manufactured structural repair materials, optimizing job efficiency, managing customer leads, and maximizing profit margins are already fine-tuned based on our proprietary data. This means that as a franchisee, you bypass the initial trial-and-error phase that plagues new business start-ups. The data we provide leads directly to faster, more profitable results and helps protect your investment in a low-cost franchise UK option.

2. The Critical Importance of Recruiting the Right Partner for Growth

Our first breakout session, titled ‘Recruiting for Growth,’ was one of the most informative of the day. Presented by the highly experienced Lee Bateman en Gemma Good of Snap-on Tools, it highlighted how absolutely vital it is to select the right individuals to join your franchise network. The research, pre-planning, and meticulous questioning are not mere formalities; they are the bedrock of success.

The session drove home the message that the alternative to careful vetting is a time-consuming, financially burdensome, and ultimately disappointing problem that can undermine the entire brand.

The Target Structural Advantage: This is where our values align perfectly with BFA best practice. A Masonry reinforcement franchise UK is a specialist business requiring dedication and a focus on quality workmanship. We are deeply committed to finding the right fit. We dedicate significant resources to pre-planning and research to ensure that every new partner we bring onboard not only has the entrepreneurial spirit but also aligns with our core brand commitment to excellence in structural repair. This strategic approach ensures the integrity of the Target Fixings brand across all UK territories, offering assurance to both customers and new investors looking to secure a high-quality UK franchise opportunities investment.

3. Harnessing AI and Brand Power to Dominate Your Local Territory

The second half of the day offered forward-looking insights that will define the next decade of franchising success:

• Piers Linney (Implement AI, former Dragon on Dragons Den) delivered an insightful and inspirational address on the future of AI. He stressed that we must get on board with AI now and actively harness its power as a tool to avoid being left behind. While AI can undoubtedly perform tasks that replace human labour, it still requires human direction. AI seeks to do a job faster and with less personnel, not necessarily ‘better’ without human guidance. Piers successfully reframed what can sometimes feel like a dystopian topic into an achievable and exciting opportunity for business growth.
• The final breakout session I attended was ‘Brand Power: Aligning local and national marketing for maximum impact,’ presented by Tom Bowers of Snap Fitness en Emma Scholes of Caremark. It was fascinating to observe how two successful, large-scale franchisors managed to achieve widespread success without using identical methods. They discussed how they provide a robust ‘blue print’ for all franchises while simultaneously granting local partners the necessary flexibility to develop their own identity within strict, cohesive brand guidelines.

What This Means for Our Franchisees: When you join Target Fixings, you are purchasing a Masonry reinforcement franchise UK that is supported by a strong, recognizable national manufacturing brand. Our franchisees benefit from high-level R&D, continuous product innovation, and national digital marketing efforts. This powerful national support means you are never alone. Furthermore, the brand guidelines are structured to allow you the necessary autonomy to implement local marketing that deeply resonates with the specific needs of your community. It is the ideal framework for securing one of the most future-proof UK franchise opportunities and achieving large-scale, sustainable success.

Ready to Be Your Own Boss in a High-Demand Sector?

The day concluded with an inspiring presentation from the final keynote speaker, Daniel Priestley (Entrepreneur, author, and founder of Dent Global), whose insights into the many advantages of franchising were genuinely motivating. I can personally recommend his book Key Person of Influence.

The evening culminated in the HSBC British Franchising Awards, a phenomenal celebration where we heard countless success stories from across the UK. Congratulations once again to everyone who won an award—we look forward to seeing you all and hearing more great news next year!

If you are inspired by the success of the UK’s top franchises and are actively looking to buy a construction franchise UK that offers technical expertise, national brand support, and a high-demand service, it’s time to take control of your professional future.
