Structural cracks in concrete are caused by movement in the foundation, resulting in long-term moving and fatiguing of concrete. Horizontal cracks or cracks wider than a quarter of an inch are general signs of a structural crack. Because the crack was initially caused by stress resulting from movement of the foundation, epoxy will not prevent further foundation cracking. The use of carbon grids (stitch) provides the necessary reinforcement.

By cross-stitching the countersunk grids within the foundation crack area, movement and fatigue are eliminated and improves long-term performance of repair material. StitchKit is designed to reinforce up to 10′ or 30′ of lineal crack, comes with carbon fiber grid stitches, tubeset of hi-mod gel (4121), and green sulzer mixers.
