VELOSIT® IR 603
Water Activated Flexible Hydrophobic Polyurethane Injection Grout
VELOSIT IR 603 is a flexible, hydrophobic, water activated, low viscosity injection grout used to stop active water leaks. It will form a permanent flexible seal within the crack, penetration, or joint.
Typical applications:
• Stopping active water leaks in cracks and joints
• Filling of large voids
• Waterproofing pipe penetrations
• Curtain Wall applications
• Suitable for both potable and waste water
Properties:
When VELOSIT IR 603 comes in contact with water it forms a flexible foam that expands 30-40% of its volume. Since VELOSIT IR 603 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 603 is mixed with IR 613 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. The VELOSIT IR 603 can be and is often used in conjunction with other products in the VELOSIT IR line.
