Product Description
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.
