Avanti AV-202-NTP Multigrout – Hydrophilic Polyurethane Injection Grout

Avanti AV-202-NTP Multigrout is a single-component, moisture-activated polyurethane injection resin engineered to seal large cracks and joints in concrete structures. This high-performance hydrophilic grout reacts with water to form a tough, flexible foam or gel that adheres to wet surfaces and expands 400% – 600% for superior water sealing. AV-202-NTP is highly effective in preventing water infiltration in applications such as manholes, pipe penetrations, tunnels, and other infrastructure requiring long-lasting leak protection. It is solvent-free, non-corrosive, and ideal for high-volume water flow conditions.

Frequently Asked Questions:

What is the difference between AV-202-NTP and AV-202 Multigrout?
AV-202-NTP offers the same sealing performance but is **not certified for potable water applications**. It is ideal for industrial and infrastructure waterproofing needs.

What are the typical applications for AV-202-NTP Multigrout?
It is used for sealing water leaks in tunnels, manholes, pipe penetrations, and other concrete structures with high water flow.

How does AV-202-NTP Multigrout work?
This polyurethane resin reacts with water to expand and create a tight, waterproof seal that adheres to surrounding surfaces.

How should AV-202-NTP Multigrout be stored?
Store in a dry atmosphere at 45°F – 95°F (7°C – 35°C) in a tightly sealed container to prevent premature activation from moisture.
