Hydrophobic Polyurethane Grouting System

DURAL AQUA-DAM is a hydrophobic polyurethane compound that is injected in concrete and other sound substrates to stop water from entering into occupied or unwanted places. The reaction time of the DURAL AQUA-DAM is controlled through the use of its accelerator, known as DURAL AQUACCELERATOR. DURAL AQUA-DAM forms a water tight seal within the substrate, that remains even after the water has subsided.

Features & Benefits

  • Bonds to wet and dry substrates

  • Needs very little water to react and cure
  • Very little shrinkage
  • Remains active when the water subsides
  • Excellent elongation to handle moving cracks and joints


  • Leaking cracks and joints
  • Mines & tunnels
  • Water treatment facilities
  • Sewers & manholes
  • Wastewater treatment facilities
  • Below grade walls subject to high water tables
