HYDROBAND HP is a thermoplastic membrane, available in a variety of widths, designed for the waterproofing of joints and cracks where a high level of movement is expected. The membrane is sealed to the substrate either side of the joint using EPONITE EP, the flexibility of the membrane allows irregular movement to a high degree whilst maintaining a watertight seal. HYDROBAND HP is available in two different thicknesses – 1mm thick membrane is suitable for joints that are lightly trafficked and expect low movement whilst 2mm is suitable where heavier traffic is expected and on all expansion joints.
