Avanti AV-202 NTP Multigrout 10.5oz Cartridge Case 12

Avanti AV-202-NTP Multigrout NTP 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.

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

Avanti AV-202-NTP Multigrout NTP Hydrophilic Polyurethane Grout, 10.5 oz Cartridge Case of 12

Avanti AV-202-NTP is a single-component, moisture-activated hydrophilic polyurethane for active water in large cracks and joints in concrete and brick. It is the non-potable grade of AV-202: same high-viscosity chemistry for manholes, pipe penetrations, and moving joints, not certified for drinking-water contact. It can take up to ten times its volume in water and cures to a tough, flexible seal, including underwater work.

Key Features

Non-potable version of AV-202 Multigrout; equivalent chemistry, not certified for potable water.
Single-component, moisture-activated hydrophilic polyurethane (MDI/TDI blend).
100% solids and non-corrosive.
Free-rise expansion of 300% to 600%.
Accepts up to 10 times its volume in water.
High viscosity of 3,200 to 6,000 cP at 77°F (25°C).
Cures flexible with excellent adhesive properties.
May be pumped as a single component without pre-mixing.
Grouting techniques include EGP, NPT, and V-PAT crack injection.
Optional AV-203 Multicat cream and gel-time accelerator.

Applications

Large cracks or joints in concrete and brick on non-potable structures.
High-volume water flow where a high-viscosity chemistry is required.
Manhole sealing and pipe penetrations (non-potable service).
Moving cracks and joints.
Use with AV-215 Resin Rod or AV-219 Fibrotite (oakum).
Underwater applications.

Frequently Asked Questions

When should I pick AV-202-NTP instead of AV-202 Multigrout?
Pick AV-202-NTP on industrial or other non-drinking-water structures. AV-202 Multigrout is the WQA NSF/ANSI/CAN 61 grade when potable contact is required. Same high-viscosity hydrophilic chemistry, different certification.

Can AV-202-NTP grout brick as well as concrete?
Yes. AV-202-NTP is engineered to seal active water leaks in large cracks or joints in concrete and brick structures. Moisture activates the resin so it can adhere in the pores of either substrate.

Can AV-202-NTP be used with AV-219 Fibrotite oakum?
Yes. AV-202-NTP is used in conjunction with AV-219 Fibrotite oakum or AV-215 Resin Rod for Expanded Gasket Placement. The resin wets the oakum and cures into a flexible gasket in the joint.

Does cured AV-202-NTP stay flexible?
Yes. AV-202-NTP cures flexible with excellent adhesive properties. That flexibility is why it is used on moving cracks and joints.

Is AV-202-NTP meant for high-volume water in large cracks?
Yes. AV-202-NTP is designed for applications where high-volume water flow is an active or potential problem and a high-viscosity chemistry is required. Typical viscosity is 3,200 to 6,000 cP at 77 F.

Does AV-202-NTP take on water as it cures?
Yes. AV-202-NTP can accept up to ten times its volume in water and free-rise expands 300 to 600 percent. That uptake is how it fills a wet opening and still cures to a tough, impermeable seal.
