Injected as a single component, catalyzed AV-275 Soilgrout is a moisture activated MDI-based polyurethane resin. The chemical reaction of this product is catalyzed by using AV-276 Soilcat and uses moisture as an initiator. AV-275 was designed to bind together and waterproof loose granular soils. AV-275 Soilgrout withstands wet/dry cycles, permeates well, and reacts quickly with water to form a dense, impermeable semi-rigid foam.
AV-275 Soilgrout is tested and certified by the Water Quality Association (WQA) against NSF/ANSI 61 – Drinking Water System Components.
