Wall ties, or tie in a cavity wall, is used to tie the internal and external walls constructed of bricks or cement blocks together. This is an essential element in the stability of a cavity wall.
Improper installation may lead to water damage or fungus formation within the cavity, leading to structural and health hazards. Wall ties are exposed to water and chemical attack from cement which requires the installation of new ties.
Our professionals use a dry-fix method to retie the outer brick with the internal brick.
