Twistfix stocks a wide selection of remedial wall ties for tying existing walls. Use stainless-steel replacement ties to secure walls where the original system fails.
Retrofit wall ties fix the outer wall of a building to the main structure. They are necessary when the existing anchors are rusting, missing or poorly fitted.
Shoddy construction can result in a poor brick tie system. Ties may be lacking or too short to suit the cavity width.
Prior to 1980, the thinking was that galvanised mild steel wall ties would last for the life of the building. Later studies show that some wall ties corrode after only 20 years. As they rot, rust deposits build up. Rusting steel can swell to many times its original thickness. The swelling steel can split and crack the mortar joints where rows of ties lay. A succession of cracks will weaken a wall. Under high winds, the walls can collapse.
A 1981 survey shows that 12 million UK homes are at risk of wall tie failure.
There are four main types of retrofit ties. Each fits into a pre-drilled hole. All are stainless-steel pins that resist rusting.
Retrofit wall ties are vital when an existing tie system has failed. Use them to strengthen and stabilise vulnerable cavity wall structures. Read our Professional Guide to Wall Tie Replacement for complete details.
