Avanti 290 Fast Set Multigrout Cartridges (12 per box)

Avanti 290 Fast Set Multigrout Cartridges (12 per box) (SS AVANTI 290) – AV-290 Fast Set is a dual-component, MDI-based polyurethane resin with mid-range viscosity, designed to quickly fill large voids outside of below-grade structures where heavy water flow is present. While effective at slowing high water flow, AV-290 should be paired with another Avanti injection resin for a complete sealing solution. This hydrophobic formula expands up to 2,600% at free rise, curing into a rigid, closed-cell material that resists moisture and withstands wet/dry cycles.

Packaging:

• Dual Chamber Cartridge (Qty: 12) – Part A: 4.2 fl. oz. (126 ml), Part B: 4.2 fl. oz. (126 ml)

Applications:

• Fills large below-grade voids fast
• Useful in pipe and tank abandonment projects
• Controls high water flows (to be used with a secondary resin)

Features & Benefits:

• Requires no water to activate
• Sets in seconds, cures rigid
• Expands 1,500%–2,600%
• Durable through wet/dry conditions
• Non-toxic formulation
• Supports multiple grouting methods: probe grouting, curtain grouting, and pressure injection

Required Components:

• AV-290 Fast Set Part A
• AV-290 Fast Set Part B

How It Works: AV-290 is injected using a static mixer that blends Part A and Part B at a 1:1 ratio at the injection site. No added water is needed, and the result is a fast-reacting, rigid grout ideal for challenging underground conditions.
