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. 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.
