Stainless steel helical bars are chemically bonded into horizontal slots, cut in bed joints, which stitch across the crack. When installed, these bars evenly redistribute tensile forces over the reinforced area to stabilise the structure. On completion, the bars and the grout are concealed, retaining the original character of the wall.

Cracks are repaired with no further damage to the wall, no costly or lengthy re-construction work and no inconvenience to the buildings inhabitants.
