JointMate control joints attach to your wall panel ties. Using a positive mechanical bond in the concrete, the control joints create a break plane where shrinkage will occur so that you can control where you want your concrete foundation to crack. The result is a straight controlled joint that is easy to waterproof. Easily cut to fit for window edges or door openings, they also stay straight under aggressive pouring conditions.
