Foundation Crack and Rod Hole Sealing
Foundation cracks and rod holes allow for easy paths of storm water migration into basements. Sealing these areas is a budget friendly option that can often resolve a water issue without the need for excavation. With this method, the crack or hole is sealed from the inside. Polyurethane foam is injected into the wall and expands to create a strong bond with the existing concrete. Unlike other methods of repair, the polyurethane foam fills the entire void up to the exterior part of the wall.
