Structural Crack Repairs using Helical Bars

This masonry crack repair video demonstrates how to install stainless steel helical bars to tie and reinforce structures having cracks in walls. Simply cut slots in existing masonry bed joints, damp down the wall and grout the helical reinforcing bars into the walls to effect the structural repairs. Tensile loads are re­dis­tri­but­ed along the masonry, via the reinforcing bars helical profile, to minimise further development of the cracks.
