Random shrinkage cracks are cracks that appear in concrete because of volume changes. These cracks weaken your structure, and allow for the penetration of moisture, leading to mold and mildew propagation. Concrete is much like any other construction material, it expands and contracts with moisture and temperature changes. These changes will inevitably produce cracks unless there is some solution put in place to control it. Making provisions for this isn’t usually easy, but Mar-flex has designed an unparalleled solution in concrete control joints. Concrete control joints are installed at predetermined locations throughout the foundation of your structure, preventing a concentration of crack-producing forces. Control joints eliminate these unsightly cracks, and provides the optimum in protection, with a complete systems approach to control joints.
