Water Cutoff | AzoGrout 443-C and AzoGrout 424

Both AzoGrout 443-C and AzoGrout 424 are waterstop grouts.

Azo-Grout 443-C

AzoGrout 443-C is single component, hydrophobic polyurethane grout used for underground concrete repair and waterproofing. The low-viscosity material penetrates cracks in rock and concrete and cures quickly to form a semi-rigid foam barrier that stops flowing leaks and repels water.  AzoGrout 443-C is approved for contact with potable water by the Water Quality Association. Use with Azo-Cat 23 to accelerate reaction time.

Applications

Underground Waterstop

  • Dams
  • Tunnels
  • Subways
  • Mines
  • Underground pipes

AzoGout 424

AzoGrout 424, designed to stop water infiltration in concrete structures, is a hydrophobic polyurethane that forms a resilient, flexible foam when it reacts with water. It can expand to up to 750% of its original volume.  AzoGrout 424 is approved for contact with potable water.  Use with AzoCat 24 to accelerate reaction time.
