VELOSIT® IR 601
Water Activated Polyurethane Injection Grout
VELOSIT IR 601 is a semi rigid hydrophobic water activated injection grout based on MDI chemistry. It is 100% solids and solvent free. It is mixed with VELOSIT IR 610 Accelerator at 2% to 10% to control reaction time of the grout.
Typical applications:
- Stopping active water leaks in cracks and joints
- Stabilization of soil
- Filling of large voids
- Waterproofing pipe penetrations
- Curtain Wall applications
- Suitable for both Potable and Waste Water
Properties:
When VELOSIT IR 601 Polyurethane Injection Resin comes in contact with water it forms a semi rigid foam that expands 30-40% of its volume. Since VELOSIT IR 601 is hydrophobic, it does not use water to form its cell structure. This results in a cured foam that will not shrink or swell and will not be affected if the treated area becomes dry.
VELOSIT IR 601 is mixed with IR 610 Accelerator at varying amounts to achieve the desired reaction and set time. Depending on the amount added and the pressure at which the resin is injected, the resultant foam may vary from closed cell to slightly open cell. Due to the low viscosity of the resin, it has the ability to penetrate under pressure and fill hairline cracks, voids, and unconsolidated areas in concrete, shotcrete and stone. It can also act as a high strength soil stablization grout. The VELOSIT IR 601 can be and is often used in conjunction with other products in the VELOSIT IR line.
