Wall ties are vital for keeping a cavity wall together and a property structurally safe. A wall tie is a stainless steel bar which stretches across the two leaves of a cavity wall and anchors them together. Over time wall ties can rust and expand up to seven times there original size causing horizontal cracking and lifting of the mortar course and in turn rust away completely leaving the cavity wall structurally unstable.
Dorset Damp Course specialise in carrying out wall tie remedial works and our specialist surveyors can inspect you wall ties and advise you on their condition and if replacement is needed.
Replacing of cavity wall ties is an external job meaning that this can be done without doing any work inside the property.
