Repair of Leaking Basement Cracks and Rod Holes

We use high pressure injection of polyurethane hydrophobic grout. The injection grout forms a flexible waterproof barrier in cracked poured concrete walls. Injected under pressure, the polyurethane will penetrate all the way through the crack to the outside soil. There it will continue to expand to fill soil voids and form a “curtain” along the outside wall. The grout remains flexible and serves as an expansion joint for seasonal movements of the basement wall. Basement rod hole leaks are fixed in a similar manner.

This method is far superior to other various resins and epoxies that harden and can lead to further cracking in the wall, typically have reduced adhesion on wet surfaces, are not a water-stop material, and do not tolerate extended movement.
