Application

• Start injection at the first packer; for vertical joints or cracks, begin with the lowest packer.
• Do not over-pressurize during injection; use the pressure that allows resin to flow into the crack or joint, avoiding pressures above 1500 psi (100 bar).
• If unreacted resin exits the joint or crack, stop injection and move to the next packer.
• After the last injection, inject a small amount of water into the packer to ensure the resin reacts fully.
• Only catalyze resin intended for use within a few hours.
• Flush the pump at the end of the day to prevent resin curing inside, which can damage the pump.

PUInjectGrout reacts with water to form a flexible polyurethane foam with the following properties:

• Absorbs movement in cracks due to its flexibility.
• Penetrates deep into fine cracks.
• Reacts with water, producing carbon dioxide gas that creates swelling pressure, expanding the resin into a foam that seals water penetration.
• Free expansion: 2700%.
• Chemically resistant to water, weak acids, alkali, and most organic solvents.
• Excellent adhesion to mineral construction materials (concrete, cement, brick), metal, and certain plastics.
