RC PU-INJECT is a resin + catalyst system, water reactive, very low viscous and solvent free. Contains polyurethane injection resin that reacts in contact with water to form a semi-flexible closed cell foam. Ideally suited for stopping water leaks (cracks/tears) in concrete or brick structures. Use with 6-10% catalyst. Is injected with a one-component pump. The end product does not shrink or swell. Good compressive strength is obtained in a very short time.

Free expansion: + 2200%.

‍

Properties:

• 2-component
• Reaction rate can be easily determined by adding catalyst between 6 and 10%
• Due to the closed cell structure of cured polyurethane resin, the cracks/joints are permanently sealed
• Low viscosity: product penetrates easily in hairline cracks (minimum 0.2 mm)
• The cured product is inert and chemically resistant
