AV 202 Multigrout
AV-202® Multigrout is a single component, moisture-activated MDI/TDI blended polyurethane injection resin. It is designed for sealing active water leaks in large cracks or joints in concrete structures. AV-202 can absorb up to 10 times its weight in water, creating a tough and impermeable with superb adhesive qualities at a 1:1 water-to-resin ratio, or gel at a 10:1 water-to-resin ratio.
Applications
- Large cracks or joints in concrete or used in conjunction with AV-219 Fibrotite™ (Oakum).
- Designed for applications where high-volume water flow is an active and/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 & Benefits
- NSF/ANSI/CAN 61 Drinking Water Systems Component Certified.
- 100% solids.
- Free rise expands 400% – 600%.
- Solvent-free and non-corrosive.
- Cures flexible with superb adhesive properties.
- Can accept up to 10X its volume in water.
- May be used in underwater applications.
- AV-202 Multigrout is available in other variations including a low viscosity (LV) and a non-potable (NTP) version.
