AV-275 Soilgrout

AV-275 Soilgrout™ is a low viscosity, moisture-activated, MDI-based polyurethane. The water/moisture activation is a two-step chemical reaction and is catalyzed by mixing AV-276 Soilcat™ with AV-275. Injected as a single component, AV-275 is designed to react quickly with moisture to bind together and waterproof loose granular soils and fill voids. AV-275 must be injected into a confined soil. AV-275 permeates well, and cures to a dense, impermeable rigid soil/grout matrix, withstands wet/dry cycles.

AV-276 Soilcat is the catalyst designed exclusively for use with AV-275 Soilgrout. Typically, one container of AV-276 is used per pail of AV-275. Depending on the desired reaction time, AV-276 may be doubled.

AV-275 Soilgrout is tested and certified for NSF/ANSI/CAN 61 - Drinking Water System Components.

APPLICATIONS, FEATURES, AND BENEFITS OF AV-275:

Fills voids on the exterior of below-grade structures
Stops high flows in below-grade structures
Stabilizes soil to prevent soil erosion, sink holes, sinking foundations, and infiltration of water and silty soils
Tested and certified by WQA against NSF/ANSI/CAN 61 Drinking Water System Component
Low viscosity allows for excellent permeation
Free rise expands up to 3,000%
Pumped as a single component (pre-mixed with AV-276)
Controllable reaction time by adjusting AV-276 volume
Withstands wet/dry cycles
Should always be injected into confined soil
