Crack Stitching

Lengths of helical HeliBar extending 500mm either side of the crack are bonded into cut slots, normally the mortar beds, with HeliBond grout for a reliable and permanent solution. Where cracks are less than 500mm from an external corner or an opening, at least 100mm should be bent round the corner and bonded into the return wall or bent and fixed into the reveal, avoiding any DPC membrane.
