Its inevitable that a structure will settle, or even suffer overload, causing cracks to form in concrete walls and the foundation of the structure. These cracks can become costly structural repairs if not expediently resolved. Crack injection has been an accepted method of repairing these cracks, because of its cost-effectiveness, reliability, and permanence. Injecting cracks allows the structure to still settle, while the injection solution binds the concrete wall back together and forms a protective barrier against moisture penetration and further cracking. Mar-Flex offers a ProKit crack injection kit that has all the tools necessary to stop these cracks before they become a major, and extremely expensive, problem. ProKit is easy to use, with instructional videos included, it is perfect for the DIY expert in your home, but is also effective enough to make the perfect injection method for contractors and other professionals.
