Description

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. Free rise expands up to 2,600%,, 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.
