Avanti AV-290 Fast-Set 10 Gallon Kit
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.
- Fill large voids below-grade
- Stops high volume leaks
- Does not require exposure to water

Avanti AV-290 Fast Set – 10 Gallon Kit
The AV-290 Fast Set 10 Gallon Kit is a high-performance, dual-component polyurethane resin system built for large-scale leak sealing and void filling. When injected, the material reacts within seconds to create a dense, closed-cell foam that resists moisture intrusion and structural movement. With an expansion rate of up to 2,600%, this hydrophobic formulation is ideal for demanding infrastructure applications such as curtain wall grouting, pressure injection, and subgrade stabilization.
This product is also available in a convenient 22oz Cartridge size.
Key Features:
- Two-component resin activates instantly upon mixing
- Expands up to 2,600% for complete void fill
- Creates a durable, rigid, closed-cell foam
- Maintains performance during wet/dry cycling
- Non-toxic and solvent-free
- Designed for heavy-duty leak mitigation and structural repair
Applications:
- Bulk filling of subsurface voids and cavities
- Mitigation of high-flow water leaks in below-grade structures
- Grouting behind tunnel liners and retaining walls
- Curtain wall injection for soil stabilization
- Large-scale infrastructure or utility system waterproofing
- Probe or pressure grouting for slab and foundation repair

Frequently Asked Questions:
What is included in the 10 Gallon Kit?
The kit includes 5 gallons each of Part A and Part B polyurethane components, shipped in separate pails for field mixing.
How is AV-290 applied?
AV-290 is typically injected using a static mixer and dual-component pump. The two parts react immediately upon mixing to form the expanding foam.
Is this product suitable for use in saturated soils?
Yes. Its hydrophobic chemistry and fast cure make it effective in fully saturated or submerged conditions.
What temperature range is recommended for installation?
For best results, AV-290 should be used between 60°F and 90°F. Material should be pre-warmed in cold conditions.
