External tanking is the coating of a waterproof membrane to the outside of a property for protection against flood risk and water damage. Consideration should be taken where solutions are needed for construction, ground water levels, ground drainage, soil type and ground contamination. The many flood control systems for external tanking include sheet membranes, pre-applied membranes, liquid systems, spray-applied elastomeric systems and cementitious systems.
Polyprufe™ is a trusted waterproof spray made from polyurea that has been developed over 20 years. It is internationally recognised as the ultimate coating system for use in waterproofing for basements, reservoirs, roof and deck finishes, concrete and steel protection, tank lining, asbestos encapsulation, pipe protection and bund lining.
Polyprufe™ combines fast curing, even at very low temperatures, and water insensitivity with exceptional mechanical properties and chemical resistance. Used on the hulls of ships, barges, aircraft carrier decks, North Sea oil rigs and platforms, this flood protection is highly durable.
