A structural repair is a repair carried out to restore the strength, stability, and safety of a building where structural movement or deterioration has occurred. Common causes include wall tie failure, subsidence, cracked masonry, failed lintels, and other structural defects that can affect the integrity of a property.

Structural problems often begin with visible signs such as cracking, bulging walls, or movement. If left untreated, these defects can worsen over time, resulting in more extensive and costly repairs.

At Northwest Wall Ties Ltd, we specialise in identifying the cause of structural defects and providing effective, long-lasting repair solutions. Our experienced surveyors assess each property individually and recommend the most appropriate remedial works to restore structural integrity while ensuring all repairs are completed to current British Standards.

Not every structural defect requires the same repair solution. Where a repair falls outside our scope of work, we work closely with a trusted network of experienced structural engineers who can provide specialist advice and design suitable remedial solutions. This ensures every customer receives the correct recommendation and the most appropriate repair for their property.

Signs of structural movement can often indicate underlying issues affecting the stability and safety of a property. Common warning signs include stepped cracking in brickwork, horizontal or vertical cracking, bulging masonry, failed wall ties, lintel failure, and general masonry movement. These defects can develop gradually over time and may become more severe if left unaddressed.

Structural movement can be caused by a range of factors, including corroded wall ties, foundation settlement, thermal expansion, moisture ingress, or deterioration of structural supports such as lintels. Identifying the cause early is essential to prevent further damage and ensure the correct remedial action is taken. Our inspections help assess the severity of movement and provide clear, honest recommendations based on the condition of the property.

We provide specialist structural remedial repairs across the Northwest using proven reinforcement systems designed to restore stability and prevent further structural movement. All repairs are professionally installed using industry-recognised methods and are backed by long-term 25-year guarantees for complete peace of mind.

Our services include masonry crack stitching, helical bar reinforcement, lintel repairs, masonry stabilisation, and structural movement repairs. These systems are designed to strengthen damaged masonry, redistribute structural loads, and provide effective long-term solutions for cracking and movement-related defects. Every repair is tailored to the condition of the property to ensure the most appropriate and reliable remedial approach is used.

Masonry crack stitching is a permanent structural repair method used to strengthen and stabilise cracked brickwork or stonework. The process involves cutting slots into the mortar joints across the crack and installing high-strength stainless steel reinforcing bars, which are bonded in place with a specialist grout.

Unlike simply filling or repointing a crack, crack stitching reinforces the wall, redistributes structural loads, and helps prevent the crack from reopening while preserving the original appearance of the masonry.

Masonry crack stitching is commonly used to repair:

• Cracked brick walls
• Stone masonry
• Structural movement cracks
• Lintel failure cracks
• Subsidence-related cracking (once movement has been addressed)
• Cracks around doors and windows

Benefits of Masonry Crack Stitching

• Restores structural integrity
• Prevents cracks from widening or reappearing
• Minimal disruption to existing brickwork
• Cost-effective alternative to rebuilding
• Long-lasting, corrosion-resistant repair
• Virtually invisible once repointed

Our Crack Stitching Service

Our experienced technicians assess the cause of the cracking before carrying out repairs using premium-grade stainless steel reinforcement systems. Every repair is completed to industry best practices, ensuring a durable, reliable, and discreet finish that blends seamlessly with the existing masonry.

Whether your property has developed cracks due to structural movement, ageing, or lintel failure, we provide professional crack stitching solutions that restore strength and give you peace of mind.

Lateral restraints are structural reinforcement systems used to secure walls and floors together, preventing walls from leaning, bowing, or separating from the rest of the building. Over time, movement, ageing, roof spread, or inadequate original wall ties can cause external walls to become unstable. Lateral restraint systems provide a reliable solution by reconnecting these structural elements and restoring the building’s stability.

The two most common forms of lateral restraint are lateral restraint straps and lateral restraint bow ties, each designed for specific structural situations.

Lateral Restraint Straps

Lateral restraint straps are heavy-duty galvanised or stainless steel straps used to securely tie external walls to internal floor or roof structures. They help prevent walls from moving outwards and improve the overall stability of the building.

These straps are typically installed where walls have become detached from floor joists or roof timbers due to age, structural movement, or poor original construction. Once fitted, they provide a strong mechanical connection that helps resist further movement.

Lateral restraint straps are commonly used for:

• Bowing or leaning walls
• Walls separating from floors or roofs
• Structural movement repairs
• Roof spread issues
• Older properties requiring additional wall restraint

Lateral Restraint Bow Ties

Lateral restraint bow ties are specialist stainless steel anchors designed to pull and secure bowing masonry walls back towards the internal structure. Installed through the wall and mechanically fixed to floor joists or structural timbers, they provide additional restraint where walls have begun to bulge or move outward.

Bow ties offer an effective alternative to more extensive rebuilding work and can significantly improve the stability of affected walls while keeping disruption to a minimum.

They are particularly suitable where traditional restraint straps cannot provide sufficient restraint or where additional structural reinforcement is required.

Benefits of Lateral Restraint Systems

• Stabilises bowing and leaning walls
• Prevents further structural movement
• Restores the connection between walls and floors
• Cost-effective alternative to rebuilding
• Suitable for both residential and commercial properties
• Long-lasting, corrosion-resistant components
• Installed with minimal disruption

Our Lateral Restraint Installation Service

Our experienced technicians carry out a thorough assessment to identify the cause of wall movement before recommending the most appropriate lateral restraint solution. Whether your property requires restraint straps, bow ties, or a combination of both, we install high-quality stainless steel and galvanised systems that comply with current structural repair standards.

Every installation is completed with care to restore structural stability, prevent further movement, and provide a durable, long-lasting repair while preserving the integrity of your property.
