Avanti 254 Grout Gelseal

Avanti 254 Grout Gelseal (SS AVANTI 254) – AV-254 Gelseal is a single-component, moisture-activated prepolymer injection resin designed for soil permeation and stabilization. Once injected into the soil, it reacts with water to form a solid, impermeable barrier that effectively blocks water infiltration and reinforces the surrounding ground structure.

Applications:

• Seals water infiltration in manholes, storm vaults, tunnels, mines, and other underground structures by stabilizing the external substrate
• Improves ground conditions and slope stability to prevent erosion, landslides, or soil movement
• Used for permeation grouting of non-cohesive soils to enhance water control and soil strength

Features & Benefits:

• One 5-gallon unit yields up to 45 gallons of active solution
• Solvent-free and non-toxic formulation
• Compatible with multiple grouting techniques, including probe and curtain grouting

How It Works:

AV-254 is applied using a multi-component variable ratio pump with one container for AV-254 and one for water. At an 8:1 water-to-resin ratio, it forms a strong gel/soil matrix; at a 1:1 ratio, it creates a more resilient foam. Cured gel properties can be modified with optional additives.

Optional Additives:

• AV-105 Gel Guard – lowers the freezing point
• AV-257 Icoset – increases gel strength
• AV-203 Multicat – accelerates cream and gel time
