One component, non-phthalate, non-solvent, VOC free, low viscosity and hydrophilic polyurethane injection system ideally for foundations, dynamic cracks and joints in concrete structures, tunnels, and masonry structures. Reaction with water yields a flexible closed cell polyurethane foam. To be injected with one-component pump.

HOW DOES HYDROFOAM WORKS?

HYDROFOAM is designed for injection of joints or repairing leaks in concrete structures. In contact with water, it forms a flexible gasket in the crack or joint. The system isideal for dynamic movement more than 10%. The resin expands and cures to a resilient, flexible closed-cell foam when in contact with water. Hydrofoam is designed to  withstand wet-dry cycles and thermal movements. Used as 1K system for injection into wet conditions or 2K system in a 1:1 ratio with water as a second component for injection into dry conditions.

APPLICATION

  • Ideal for sealing between foundation and structure interface.
  • For sealing of dynamic cracks and joints.
  • For sealing tunnel segment joints/ tunnel eye.
  • Curtain grouting behind concrete/ tunnel segments.
  • Used as a 1-component or 2-component

HYDROFOAM is meant to be used as a ONE·PASS method, the tough flexible foam is generally unaffected by corrosive environment. HYDROFOAM is a next generation 1 component injection resin with enhance permanent leak sealing and waterproofing performance.

 

OPERATIONAL DATA

HYDROFOAM can be used as a 1-component system for injecting into wet conditions; or as a 2-component system with a 1:1 ratio water for injecting into dry environment. Pumps should be cleaned with MEK, Acetone, or any solvent cleaning agent for cleaning of polyurethane injection pumps.

PACKAGING

  • 20 kg plastic jerry can
  • 1 pallet= 48 cans

STORAGE

 

HYDROFOAM is sensitive to humidity. Store away from frost and heat in a dry area. Optimal storage temperature is between S°C and 30°C. Open cans should be finished as soon as possible. Shelf life is 1 year.
