Product description

PENTAFLEX® FTS Rated-Crack Elements belong to the recognized and proven PENTAFLEX® Joint Sealing System for producing watertight concrete structures (white tank). They are used to produce rated-cracks in element walls and are specially designed to seal vertical joints in element construction. The FTS Rated-Crack Elements consist of a joint sheet with the proven PENTAFLEX® special coating, as well as a flank made from galvanized steel sheet. This attenuates the cross section of the concrete and also provides attachment for the flashing. Simultaneously, the crack that occurs is secured against pressurized and non-pressurized water by the integrated flashing.
