RESINBAU · INJECTION SYSTEMS
A true one-component hydrophilic polyurethane resin. It cures on contact with water in damp cracks and water-bearing joints, forming a flexible seal. Use a one-component pump where sufficient water is present; a two-component pump can feed resin and water separately at a 1:1 ratio. No second resin component is required. Clean the equipment with PI-Cleaner and preserve it with PI-Saver in accordance with the technical data sheet.
