Polyurethane foam can be very effective in sealing leaking cracks in foundation walls and floors, in both residential and commercial applications. It is also good in sealing culverts and tunnels. The polyurethane foam is injected from the inside, through the concrete wall, to form a permanent waterproof barrier that adheres to the outside of the concrete wall displacing moisture and water. This method of sealing compared to other methods, solves the root cause of the problem by addressing the issue on the outside of the wall rather than only sealing the crack on the inside, which over time may allow water to eventually push through again.

Installation is easy with minimum disruption or mess. This process is cost effective, and also adds an insulating value to the wall or floor where foam is added.
