Manhole Rehabilitation

Chemical Grout

AV-100®

AV-100® Chemical Grout, also known as Acrylamide Grout, has a successful track record spanning over 50 years in controlling groundwater and stopping infiltration. Renowned for its exceptional strength and durability, AV-100 is the go-to solution for mitigating water infiltration in a wide range of underground structures, including manholes, mainlines, laterals, lateral connections, tunnels, and mines. It accomplishes this by establishing a durable and efficient water barrier on the exterior of the structure.

AV-275 Soilgrout

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-202® Multigrout

AV-202® Multigrout is a single component, moisture activated MDI/TDI blended polyurethane injection resin. Designed for sealing active water leaks in large cracks or joints in concrete structures, it can absorb up to 10 times its weight in water, creating a tough and impermeable with superb adhesive qualities at a 1:1 water to resin ratio, or gel at a 10:1 water to resin ratio.

AV-290 Fast-Set

AV-290 Fast-Set is a mid-range viscosity, dual component, hydrophobic MDI-based polyurethane resin designed to rapidly fill large voids on the exterior of below grade structures where high water flow is present. Expanding between 1,500% and 2,000%, the fast-setting resin cures to form a rigid, impermeable closed-cell foam that can withstand wet/dry cycles. AV-290 does not require any water to react.
