CrackWeld is a low-viscosity, fast-curing urethane crack filler designed for repairing cracks in horizontal concrete floors and slabs, including garage floors, basements, and driveways. It cures to a rigid repair that is stronger than concrete and penetrates both hairline and wider cracks—no routing required for quick, nearly seamless repairs. The kit comes complete; all you need is a standard caulking gun.
