Cavity wall tie replacement

Cavity wall tie replacement

Why is cavity wall tie replacement required?

There are two primary factors that necessitate the replacement of wall ties in a building:

  • Wall tie failure: Wall ties can fail due to corrosion resulting from chemical reactions between metal, moisture, and oxygen. This corrosion leads to the formation of brittle iron oxide layers, weakening and eroding the steel tie-irons over time.

  • Defective design or construction: Sometimes, the brick tie system integrated into the construction is improperly installed. This can occur when ties have insufficient embedment depth or when an insufficient number of ties are incorporated into the structure.

In both scenarios, installing a remedial wall tie replacement system is crucial. This ensures that the outer wall remains securely connected to the building’s main structure, thereby preserving stability and enabling the effective transfer and sharing of applied loads.

Types of replacement wall ties

Our premium replacement wall ties are meticulously crafted from austenitic stainless steel, ensuring unparalleled durability and corrosion resistance. With various lengths tailored to accommodate cavity widths of up to 110mm, our replacements guarantee a precise fit for your structure.

Each design includes a strategically integrated drip detail, meticulously engineered to thwart the infiltration of water across the cavity, safeguarding your walls against moisture-related issues.

For those seeking alternative options, we offer a diverse array of wall tie designs, including resin, drive tie, or cementitious variants. Your surveyor will conduct a thorough assessment to determine the optimal solution based on the specific type and condition of the masonry, ensuring the utmost suitability and effectiveness for your needs.

Warren and his team were friendly and efficient, working well together to get the job done properly and quickly. He quoted for the work back in September, and the price stayed the same despite us not confirming the go-ahead until December. All in all professional and I would recommend them to anyone needing wall ties in future.

Very professional manner and very thorough in his work. Extremely approachable, happy and pleasant. Very highly recommended.

After wall tie failure was highlighted on our building survey, North West Wall Ties produced a professional pre-purchase report for us in really good time, and gave us what seems a perfectly reasonable quote for the work. Hopefully our purchase goes through and then we’ll be able to get the required work done with this company.
