CONCRETE Crack Injection

So serious, we won't crack

To fix hairline concrete cracks in structural foundation walls, floors, ceilings and more, injectable polyurethane is a cost-effective, flexible, and long-lasting repair for most types of cracks. Constant temperature stress, traffic, and other factors can cause unsightly cracks in concrete walls, ceilings, sewer systems, basement walls, and manholes over time, which can sometimes present safety hazards. For these smaller, more isolated concrete breakages, a polyurethane resin concrete 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. A low-pressure injection method of polyurethane resin is used to fill cracks from behind. This injection method seals actively leaking joints and cracks in concrete structures, and restores concrete integrity.  When injected into drilled injection ports along the crack, 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. 

The problem
Our Solution

Our injection repair procedure for cracks always begins with adequate preparation. Holes or “injection ports” are drilled along the crack on both sides, and the crack is then flushed with water, so as to maximize adhesion with a clean surface.  Finally, we use a dispensing tool to inject polyurethane resin into each injection port location to 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 that can repair many types of cracks and concrete floor, wall or ceiling breakages.
