VELOSIT® IR 602
Low Viscosity Flexible Hybrid Polyurethane Injection Grout
VELOSIT IR 602 is a two component Flexible hydrophobic injection grout based on MDI chemistry. It is 100% solids and solvent free.
Typical applications:
-
Damp or Dry Cracks
- Hairline Cracks
- Sealing of Construction Joints
- Waterproofing pipe penetrations
- Tunnels, Dams Bridges
- Waste Water Tanks
Properties:
When VELOSIT IR 602 comes in contact with water it forms a flexible gel resin under pressure. Since VELOSIT IR 602 is hydrophobic, it does not use water to form its cell structure. This results in a cured resin that will not shrink or swell and will not be affected if the treated area becomes dry.
VELOSIT IR 602 can also be used to seal dry cracks as it does not need water to cure. When water is not present and the resin is injected under pressure, it will form a flexible solid body gel that undergoes little to no foaming. If water is present, the product will foam and stop any active water leaks. A dual injection is usually done with the VELOSIT IR 602. First, the leaking crack or joint is injected and the VELOSIT IR 602 will foam and stop the active leak. After 15 minutes, the area is injected again with VELOSIT IR 602. The VELOSIT IR 602 will then fill in around the foam creating a secondary seal in the form of a solid body resin, making the area watertight. 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, masonry, shotcrete and stone.
