External Tanking Treatments
Comprehensive external waterproofing solutions that protect your property from ground water penetration, hydrostatic pressure, and external moisture damage at the source.
What is External Tanking?
External tanking involves applying waterproof coatings or membranes to the outside of below-ground structures to prevent water penetration. This is the most effective method for keeping basements, cellars, and underground spaces completely dry.
