At Stronghold Preservation we are adept at waterproofing both new and existing basements.  For new build basement projects, we provide a design service at the drawing stage to ensure that the basement construction is tailored for each individual project.  Where the project is for an existing basement, we have over 25 years experience at trying to find and eliminate the source of the damp ingress, and providing a solution for each individual problem; whether that is installing a new waterproofing layer to the building fabric, or sealing leaks in otherwise sound construction.

We have experience in many project types; poured concrete basement, lift pit sealing, service duct sealing, & residential.
