PENTAFLEX KB® joint sheets are suitable for sealing construction joints in watertight concrete structures. They are resistant to a wide range of organic and inorganic media. PENTAFLEX KB® can be used for construction joints exposed to pressurised and unpressurised water in wall/base or wall/slab areas and in wall/wall or floor/floor areas. The high elasticity of the special coating forms a secure seal in the event of the concrete components shrinking. An anchoring depth of 30 mm is sufficient to withstand a water pressure of 5 bar. A guide marking indicates the correct installation depth.
