Injected as a single component, catalyzed Avanti AV-275 SoilgroutTM 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 rigid foam.
Applications 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.
Low viscosity allows for excellent permeation. Expands up to 3,000%. No VOC. Pumped as a single component. Controllable reaction time by adjusting AV-276 volume. Withstands wet/dry cycles.
Requires applicator gun. See datasheet for full specifications.
