AV-275 Soilgrout is a low viscosity, moisture activated, MDI-based polyurethane resin whose chemical reaction 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 forms a dense, impermeable, rigid soil/grout matrix, withstands wet/dry cycles and permeates well.
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.
• 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
AV-275 Soilgrout is tested and certified for NSF/ANSI/CAN 61 - Drinking Water System Components.
