PROSOCO Stitch-Tie®, formerly called CTP Stitch-Tie, is a stainless steel helical pin that reattaches existing masonry facades to backup structures. These retrofit ties can stabilize veneers of brick, stone, masonry, or precast concrete that have missing or corroded wall ties. The process eliminates the need to tear down and replace existing facades, and preserves the beauty and historical integrity of existing buildings.
