AV-100® Chemical Grout (Acrylamide)

AV-100® Chemical Grout (Acrylamide)

With over 50 years of successful documented use, AV-100® Chemical Grout (Acrylamide) is used to stop water infiltration into manholes, mainlines, laterals and lateral connections, tunnels, mines, and other underground structures by creating an effective, long-lasting water barrier on the exterior of the structure. AV-100 Acrylamide is an ultra-low viscosity, chemically reactive gel that travels anywhere water can travel and cures in controllable set times from seconds to several hours. Once cured, it creates an effective, long-lasting water barrier while providing superb soil stabilization. 


  • Stops water infiltration into manholes, sanitary and storm sewer mainlines, joints, laterals, tunnels, mines, and various other geotechnical applications and underground structures by stabilizing external substrate
  • Ground modification/slope stability for prevention of landslides, erosion, or any place where site conditions or project requirements dictate modification of the existing soil properties
  • Controllable reaction times from seconds to hours
  • AV-100 Acrylamide has a half-life of 362 years for 20% grout concentration, as determined by U.S. Dept. of Energy
  • Higher strength compared to acrylates, greater longevity compared to silicates
  • Available for purchase as certified for NSF/ANSI/CAN 61 - Drinking Water System Components for granules or liquid

To purchase and use our acrylamide and acrylic grouts, we require that you complete the Safe Operating Practices Program - a training guide for users of any of our acrylic injection grouts.
