OverviewSpecifications

Prime Flex 920 is a single-component polyurethane injection resin used to seal gushing leaks, including wide gaps in concrete, where the structure is not subject to movement. This hydrophobic, super low viscosity polyurethane reacts with water and expands to form a closed cell, watertight, rigid foam. Due to its low viscosity, 920 is also used for permeation grouting of loose soils to consolidate soil particles and increase the load-bearing capacity. This product is independently tested and verified to meet NSF/ANSI Standard 61 for contact with potable water.

Recommended Uses:

  • Injection of gushing water leaks in below-grade structures
  • Injection of loose soils for stabilization
  • Curtain grouting manholes, pipe joints, tunnels, etc.
  • Point grouting

Typical Areas of Use:

  • Sealing leaks and wide gaps in concrete. Examples:
    • Box culverts, tunnels (subway, water, utility, etc.)
    • Manholes, sanitary and storm pipes/structures
  • Curtain grouting below-grade structures. Examples:
    • Parking decks
    • Manholes
    • Foundations and basements
  • Permeation grouting for soil stabilization. Examples:
    • Roads and highways
    • Seawalls and retaining walls
    • Sinkhole perimeters (not filling the sinkhole)

Advantages:

  • NSF/ANSI Standard 61 compliant for potable water contact
  • Cheaper and less disruptive than replacement
  • Super low viscosity: penetrates into fine areas
  • Pumped as a single component
  • Available in convenient cartridges
  • Up to 2900% expansion (unconfined)
  • Variable reaction (set) times
  • Meets Fla. DOT specification for soil injection of chemical grouts
  • Watertight on gushing leaks
