Avanti AV-290 Fast-Set 22oz Cartridge Case 6

AV-290 Fast-Set is a mid-range viscosity, hydrophobic polyurethane resin designed to rapidly fill large voids on the exterior of below grade structures where high water flow is present. Expands between 1,500% and 2,000% and quickly cures to form a rigid, impermeable closed-cell foam that can withstand wet/dry cycles.

Avanti AV-290 Fast Set – 22oz Cartridge

AV-290 Fast Set is a two-component, hydrophobic polyurethane foam formulated to stop high-volume water infiltration and fill large voids around below-grade concrete structures. It expands up to 2,600% and cures rapidly into a rigid, closed-cell foam that resists wet/dry cycling. Designed for use in curtain grouting, probe grouting, and pressure injection, AV-290 is solvent-free, non-toxic, and highly effective in saturated soils or areas with persistent groundwater intrusion.

This product is also available in a convenient 10 Gallon Kit bulk size.

Frequently Asked Questions:

How fast does AV-290 Fast Set cure?
The resin cures in approximately 40 seconds after injection, depending on temperature and site conditions.

What is the expansion capacity of the foam?
AV-290 expands between 1,500% and 2,600% of its original volume, effectively filling large voids and sealing leaks.

Can AV-290 be used in areas with continuous moisture?
Yes. The rigid foam withstands wet/dry cycling and is suitable for high-moisture environments.

How is AV-290 applied in the field?
It is injected using a dual-chamber cartridge or pump with a static mixer. Mixing the components at the point of injection ensures rapid reaction and expansion.
