Avanti manufactures professional-grade injection grouts used to stop water infiltration, stabilize soil, and restore concrete in infrastructure and environmental containment projects. Their polyurethane grouts, including AV-202 Multigrout, expand on contact with water and are NSF 61 certified for use in potable water systems. Contractors rely on Avanti products to seal pipe penetrations, utility vaults, below-grade walls, and manholes in both active leak and dry conditions. Single- and multi-component systems are available for a range of field conditions, from saturated soils to confined spaces.
