Why Wall Cracks Happen
One of the common reasons that foundation walls begin to crack is bowing walls, or walls being pushed inward. This happens because of three soil-related reasons: expansive soils, lateral earth pressure, and hydrostatic pressure. In all cases, foundation walls buckle under the force and create other forms of damage in your home, like wall cracks.
The other type of foundation problem that typically creates wall cracks is foundation settlement. Settling happens when the soil beneath your home can no longer handle its weight. Pockets of weak soil sink, bringing your house down with it. As your foundation shifts unevenly, cracks begin to appear in the walls.
Our Polyurethane Crack Injection Solution
Our preferred wall repair system for repairing cracks in a concrete foundation is to inject expanding polyurethane sealant into the crack. Epoxy can also be used to repair cracked concrete, but polyurethane offers some important advantages.
Polyurethane is a man-made resin that's highly expansive and has significant adhesion. It will adhere to just about any material. We use an expanding geotechnical polymer formulation that flows into gaps and voids, filling them completely before the resin hardens to form a waterproof seal. The cured sealant is flexible so that it won't crack if there's slight movement along the crack, and it can't be degraded by salts and other chemicals that might leach through the soil.
