KUNEX® thermoplastic (PVC-P) star tubes create and seal dummy joints and target rupture joints in concrete. Star tubes consist of a soft PVC cladding with four stop anchors and two rupture formation lips. The star tube is installed with an inner tube made of hard PVC for the purpose of stabilising the cladding. The two rupture formation lips are used to create the target rupture in a controlled manner and the target rupture simultaneously seals the four stop anchors.
