Koster 2 IN 1 stops active leaks and seals cracks and construction joints permanently and elastically. It can be injected in dry and wet cracks. The material can also be used for filling of voids
2 IN 1 is a water reactive elastic PU-injection resin for single and two stage injection of dry and water bearing cracks and joints.
When Koster 2 IN 1 resin comes into contact with water, it reacts to form a highly elastic foam. When 2 IN 1 resin is injected under dry conditions, it reacts to form a solid body elastic resin. Koster 2 IN 1 remains permanently elastic after reacting. It is therefore able to follow crack movements and seal cracks permanently with an elastic polyurethane solid resin without necessitating follow-up injections.
