PENTAFLEX® is a system for sealing joints designed for the construction of water-impermeable concrete structures (white tank). The PENTAFLEX KB® seam sheet elements are ideally suited for use in prefabricated constructions and in-situ concrete constructions and were designed for structures of high-grade use. They are provided on both sides with a special coating which, in connection with the fresh concrete, reliably prevents water infiltrating the joint system. PENTAFLEX KB® elements can be used for all construction joints and installation types (horizontal/vertical, pressing/non-pressing water).
