Nitofill PU 1F is a one-part liquid pre-polymerized polyurethane resin injection grout. When in contact with water, the resin reacts to form an elastic expanding foam barrier that blocks the flow of water in leaking cracks. The system is ideal for movement of the substrate in excess of 10%. Nitofill PU 1F is designed to withstand wet-dry cycles and thermal movements.
- Truly 1 component, does not require mixing or the addition of catalyst
- Reacts rapidly with water to produce water resistant foam to seal cracks
- Provides permanent elastic seal
- Non-toxic when cured.
- Low viscosity allows penetration into fine cracks.
- Excellent adhesion properties to a range of construction materials.
- Suitable for single component injection pumps
