Product Description

The Crack Stitch is a high-quality product ideal for concrete wall repair. Our product is easy-to-use for vertical concrete crack repair and reinforcement for concrete floors, foundation walls, and swimming pools.

Our reinforcement system is a pre-impregnated, bidirectional carbon fiber grid strap. This system excels when used with Epoxy injection since the grid stitch has more surface area than staples. This surface area creates a stronger and more effective bond and ensures your home has the stability it needs.
