So serious, we won't crack
Constant temperature stress, traffic, and other factors can cause unsightly cracks in concrete walls, ceilings, sewer systems, basements, and manholes over time, which can sometimes present safety hazards. For these smaller, more isolated concrete breakages, a polyurethane resin crack injection is the quickest and most effective long-term solution that can save you both time and money. Polyurethane resin is a thin liquid that reacts with water and expands to form a closed cell, watertight foam. It is used to seal actively leaking joints and cracks in concrete structures, particularly hairline cracks which can worsen over time.
A low-pressure injection of polyurethane resin is injected into cracks to stop leaks and restore concrete integrity where fine cracks exist. When injected, the resin expands to fill the crack completely. The resin will begin to harden and foam within minutes of injection. While concrete continues to shift, the polyurethane resin remains flexible, and ensures there is no future water leakage.
Our Applied installation procedure for crack injection always begins with adequate preparation. Holes are drilled along the crack on both sides, and the crack is then flushed with water, as adhesion is maximized on a clean surface. Finally, the crack is injected with polyurethane resin at each location to completely fill the crack from behind. This polyurethane resin expands to up to 20 times its size and weight to fill all cracks and voids in an effective, watertight manner. It’s also an environmentally friendly product and procedure.
