StenCare® 2IP-4 is a solvent-free, two-component polyurethane injection material with a 1:1 mixing ratio. On contact with water it hardens rapidly, forming an impermeable, semi-flexible foam that stops leaks. Its low viscosity and slow gelling allow deep, long-distance injection. It adheres perfectly to concrete, has low flammability and is solvent-free, containing no volatiles harmful to health (VOC=0).
Areas of Use
StenCare® 2IP-4 is used to provide waterproofing in underground constructions and tunnel applications. Even after the two components are mixed, the reaction does not advance until the material contacts water, which permits long-distance injection. It penetrates deeply, filling voids and cracks between layers with resin, and on contact with water it cuts off water flow by forming an impermeable, semi-flexible foam.
