Self-Tapping Stainless Steel Wall Ties

The helical, stainless steel wall ties are quickly and easily installed; a hole is drilled and the wall tie is effectively screwed into the masonry wall, firmly holding the 2 skins of masonry together.  Once the new wall ties have been installed, the old wall ties must be removed to stop further bowing, bulging and brickwork cracking. This normally can be done entirely from the outside; our operator will cut out the brick beside the existing tie, remove the tie and then replace the existing brick.
