This AB Tools Cavity Wall Tie is designed for builders constructing cavity walls in residential and commercial properties up to 10 meters high. Its primary benefit is providing a secure connection between two layers of masonry, preventing structural instability and moisture ingress, thanks to its durable stainless steel construction and double drip feature. A caveat to consider is its specific cavity width range, which must be matched to the project requirements.

Verify that the cavity width is within the specified range of 76-100mm. Ensure no obstructions are present in the cavity. If the cavity is too wide, a different type of wall tie may be required.

This is highly unlikely with grade 304 stainless steel. If observed, it may indicate contact with dissimilar metals or corrosive substances during installation or from external sources. Consult a structural engineer or building professional.
Setup:
Install the wall ties during the construction of the cavity walls. Ensure the ties are embedded correctly into the mortar joints of both the inner and outer masonry leaves. Refer to BS EN 845-1 for precise spacing and installation guidelines. The tie's length of 225mm and cavity width compatibility of 76-100mm are key parameters to observe during installation.
Compatibility:
This cavity wall tie is suitable for:
It is designed for use in buildings with a maximum height of 10 meters.
Care:
As the tie is made from grade 304 stainless steel, it requires minimal maintenance. It is inherently resistant to rust and corrosion. However, ensure that the surrounding mortar is properly cured and maintained to support the tie's function effectively. Regular inspection of the wall structure is recommended as part of general building maintenance.
