DESCRIPTION
AV-202 Multigrout is a single component, moisture activated MDI/TDI blended polyurethane injection resin. Designed for sealing active water leaks in large cracks or joints in concrete structures, it can absorb up to 12 times its weight in water creating a tough, impermeable foam or gel with superb adhesive qualities. Certified for use in potable water.
APPLICATION
- Large cracks or joints in concrete, or used in conjunction with AV-215 Resin Rod or AV-219 Oakum systems
- Designed for applications where high-volume water flow is an active or potential problem and a high viscosity chemistry is required
- Used successfully in manhole sealing and pipe penetrations
- Excellent choice for moving cracks and joints
FEATURES AND BENEFITS
- ANSI/NSF 61 Potable Water Systems UL Certified
- 100% solids
- Expands 400% – 600%
- Solvent-free and non-corrosive
- Forms a resilient, flexible foam with superb adhesive properties
- Can accept up to 12X its weight in water
- Thickest resin on the market
- May be used in underwater applications
GROUTING TECHNIQUES
- Expanded Gasket Placement Technique (EGP)
- Variable Pressure Application Technique (V-PAT) – Crack Injection
HOW IT WORKS
AV-202 can be applied via two techniques: EGP or V-PAT. The resin reacts to moisture to form a resilient, flexible seal accomplished by three mechanisms: the resin seeks out water in the space and adheres to the surface, then begins to expand forming a tight compressive seal, while the network of compressed grout material within all the cracks forms a mechanical lock.
RATIOS*
Preferred ratio is 1:1 (water to resin), however no pre-mixing is required. Pumped as a single component and is effective at ratios up to 12:1 with water.

PERFORMANCE
Flush equipment with AV-208 before and after use to remove moisture and clean equipment. For best results, use between 60 degrees Fahrenheit – 90 degrees Fahrenheit (16 degrees Celsius – 32 degrees Celsius). Performance will be influenced by site conditions. If site temperatures are low, use a heat source to warm to ~72 degrees Fahrenheit (22 degrees Celsius) and apply. Do not use open flame as a heat source.
CLEANING PRODUCTS
- AV-208 Acetone, Technical Grade (CAS No. 67-64-1) – removes moisture from equipment (see Performance section).
- AV-284 Pump Wash (Proprietary Blend) – removes uncured resin from pump and hose.
- AV-222 Cleaner (Proprietary Blend) – removes cured resin from equipment.
STORAGE
Store in temperatures within or near 60 degrees Fahrenheit – 100 degrees Fahrenheit (16 degrees Celsius – 38 degrees Celsius) in a dry atmosphere.
SAFETY
Always use OSHA-approved personal protective equipment (PPE). Refer to the MSDS for complete safety precautions. The MSDS is available by request.
