Over time, the process of corrosion of mild steel cavity wall ties causes original wall ties to expand. This expansion has the effect of forcing apart the bricks above and below the bed joints in which the wall ties are laid, producing a pattern of horizontal cracks coinciding with the tie positions approximately every six courses.
The corrosion of the cavity wall ties or the lack of sufficient cavity wall ties used in the original construction means that many properties require either further replacement wall ties to be inserted or the original cavity wall ties replaced.
Our remedy for cavity wall tie corrosion is a straight forward procedure,we carry out a survey of the existing wall ties by locating, drilling and inspecting them.
We then install replacement wall ties without the removal of any brickwork in positions staggered from the original cavity wall ties.
Wall tie replacement is carried out in a uniform spacing pattern: a diamond formation with remedial wall ties at 900mm centres in courses set 450mm apart. At door and window openings the spacing is reduced to 300mm vertically.
The original cavity wall ties then need to be isolated to prevent further damage to the cavity wall. Isolation of the cavity wall ties can be achieved by fitting sleeves around the external end of the cavity wall tie or complete removal of the cavity wall tie.
We have a range of stainless steel replacement wall ties to suit most situations as well as other types of stainless steel restraints, stitching bars and anchors to deal with the problems caused when buildings deteriorate and are no longer structurally sound.
We also carry out repairs to brick arch lintels, stitching of structural cracks and installation of lateral wall restraints that prevent bulging walls by restraining the brickwork through to internal walls / floor joists.
All of our works are covered by a company guarantee. A separate GPI insurance backed guarantee is also available.
