Basement tanking and pool waterproofing, resistant to water pressure.
Tanking makes buried structures watertight against water pressure — basements, lift pits, tanks, crawl spaces. The same expertise applies to pool and basin waterproofing, where water is held inside the structure.
Depending on the situation, we use waterproof mortars, epoxy or polyurethane resins, or reinforced membranes, able to resist positive water pressure (from outside) as well as negative (from inside). Systems are chosen according to the target watertightness class and, for pools, compatibility with water and treatments.
