Avanti AV-202 Multigrout – 5 Gallon

Avanti AV-202 Multigrout is a hydrophilic polyurethane injection resin used to stop active water infiltration in large concrete cracks and joints. This moisture-activated, single-component system forms a flexible, adhesive foam that fills voids and forms watertight seals. Capable of absorbing up to 12 times its volume in water and expanding 400–600%, AV-202 is a proven solution for infrastructure, utilities, and below-grade waterproofing. It meets NSF/ANSI 61 standards for use with potable water and performs in both wet and submerged conditions.

Key Features:

Hydrophilic formulation reacts with water to seal active leaks
Foam expansion up to 600% for deep penetration
Certified for potable water systems (NSF/ANSI 61)
Non-corrosive, solvent-free, and 100% solids
Adheres well to concrete, even in moving joints
Can be used in underwater or high-moisture applications

Applications:

Sealing active water intrusion in concrete joints and cracks
Waterproofing for manholes, tunnels, and vaults
Subsurface pipe penetrations and underground structures
Grouting around oakum or resin rods in leak-prone areas
Infrastructure repairs in water utility and transportation sectors

Frequently Asked Questions:

How does AV-202 Multigrout function in wet environments?
The hydrophilic resin reacts with moisture and expands into a compressive, water-blocking foam. It works in fully submerged and saturated conditions.

What is the preferred mix ratio for injection?
Although it’s pumped as a single component, it reacts effectively with water at ratios up to 12:1. No pre-mixing is needed.

Is it safe for use in drinking water systems?
Yes. AV-202 is NSF/ANSI 61 certified for use in potable water system components.

What temperature range is recommended for application?
For best results, apply between 60°F and 90°F. Cold temperatures may thicken the resin and slow reactivity.
