H-BAU Technik PENTAFLEX® joint sheets are the first choice for sealing watertight structures made of concrete in accordance with the German watertight structure guideline. They are suitable for horizontal and vertical construction joints in pressurised and unpressurised water. In addition, they can be used in both precast and in-situ concrete construction. The joint sheets are completely covered with a special coating on both sides. This coating reacts with the fresh concrete to reliably prevent water from infiltrating the joint system. The PENTAFLEX® sealing system is suitable for use in structures of stress class 1 and service class A in accordance with the German watertight structure guideline and so meets the highest requirements.
