Waterproofing an old limestone foundation from the exterior with âClosed Cellâ spray polyurethane foam provides a water tight seal from the outside.
Spray foam is sprayed onto any open surface and studded wall (including metal). A trained Spray Foam installer is required. As with any open surface, Spray Foam can be sprayed on once electrical and plumbing services are in place. In seconds, Spray Foam expands to 100 times its initial liquid volume permanently adhering to the surfaces of the surrounding building materials and sealing all gaps.
