Internal or external KUNEX® construction joint tapes are made of thermoplastic polymer (PVC-P) and are suitable for sealing horizontal and vertical construction joints in in-situ concrete construction. They reliably prevent infiltration of the joint system when exposed to pressurised and unpressurised water or soil moisture. Thermoplastic joint tapes can be welded together to ensure they are watertight. KUNEX® construction joint tapes can be used for construction joints in wall/base, wall/slab, wall/wall, slab/slab or floor/floor areas.
