Avanti Adds Grouts to Growing NSF/ANSI/CAN 61 Certified Product Line

Avanti International’s AV-150 Acrylate Gel™ and AV-278 Low Vis Hydro™ are now certified by the Water Quality Association (WQA) as tested and certified as complying with NSF/ANSI/CAN 61 - Drinking Water System Components.

Avanti’s injection grout products are used to stop leaks, stabilize soil, and control groundwater in municipal, industrial, and geotechnical applications around the world. According to Technical Director Roger Borremans, “These products join other Avanti grouts that have earned the potable water certification. The rigorous tests they are put through by WQA per the NSF/ANSI/CAN 61 standard ensures the products are safe to use near drinking water sources.” 


About the Products

  • AV-150 Acrylate Gel™ is a low viscosity, chemically activated acrylate gel. This high-solids acrylate can permeate most geologies and cures within a controllable timeframe from 20 seconds to ±5 minutes.  Once cured, it creates an effective, strong, 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.
    • High solids content grout
    • Controllable reaction times from seconds to minutes
    • Available in 44-lb. pails, 484-lb. drums, and 2,420-lb. totes
  • AV-278 Low Vis Hydro™ is a moisture activated, MDI-based polyurethane. The chemical reaction is catalyzed by mixing AV-279 Low Vis Accel with AV-278 and injecting as a single component. AV-278 uses moisture as an initiator and is designed with soil permeation in mind – it has a low viscosity that allows for soil penetration and has high expansion properties to fill voids, stop active or potential water leaks, and stabilize soils. AV-278 withstands wet/dry cycles and forms a dense, closed-cell, impermeable semi-rigid foam.
    • Fills voids on the exterior of below-grade structures
    • Stops leaks in below-grade structures 
    • Low viscosity allows for excellent permeation 
    • Free rise expands 4,000-6,000% 
    • Withstands wet/dry cycles 
    • Controllable reaction time by adjusting AV-279 catalyst volume
    • Multiple packaging variations available:
      • 8.0 fl. oz. x 2.0 fl. oz. barrier cartridges (case of 12)
      • 25.3 fl. oz. x 2.5 fl. oz. dual cartridges (case of 6)
      • 8-lb. containers
      • 44-lb. pails
      • 484-lb. drums


Avanti has a growing line of products that are NSF/ANSI/CAN 61 tested and certified including: AV-202 Multigrout, AV-248-LV Flexseal LV, AV-275 Soilgrout, AV-315 Microfoam, AV-330 Safeguard and Ultrafine SD. For more information on any of these products, visit avantigrout.com.


Regarding NSF 61, being "certified" vs. being "compliant" means two very different things. “We believe it's important that these products go through proper third-party testing to become NSF certified, not just self-claimed as compliant” says Britt N. Babcock, President of Avanti. “Completing the extensive process of third-party laboratory testing and auditing with WQA validates product safety and consistency – from raw materials to manufacturing facilities to final products. We are proud to offer NSF/ANSI/CAN 61 certified products to our customers!”
