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.

• 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

Injected as a single component, catalyzed AV-248 Flexseal is a moisture activated MDI-based polyurethane resin. The chemical reaction is catalyzed by using AV-249 Flexseal AC and uses moisture as an initiator. Like other hydrophobics, AV-248 Flexseal withstands wet/dry cycles and reacts with moisture; but unlike other hydrophobics, it forms a resilient, impermeable flexible foam. This high quality resin is designed for sealing active and potential water leaks in various cracks, and annular spaces where flexibility is needed but is susceptible to wet/dry cycles. Avanti’s AV-248 is one of the most versatile products on the market.

• For use above or below grade in humid or arid atmospheres
• Fills various cracks and pipe penetrations
• Stops leaks in concrete structures
• Designed for tunnels, mines, dams, reservoirs, block walls and
• structures that may shift

AV-330 Safeguard is a 100% MDI-based, single component, mid-range viscosity, moisture activated polyurethane injection resin. This high quality water-activated resin is designed for sealing active leaks in below grade structures. It is a mid-range viscosity grout that permeates well in various cracks and joints, but offers added safety in confined spaces or where there is poor ventilation. It cures to become a resilient and flexible, yet tough, closed-cell foam. Certified for use in potable water.

• Areas with poor ventilation or confined spaces (utility vaults, sub-grade pump houses, lift stations, mines, tunnels, and basements)
• Medium cracks or joints in concrete structures
• Great for manholes and pipe penetrations

AV-333 Injectaflex is a single component, mid-range viscosity, moisture activated polyurethane injection resin. This high quality resin is designed for sealing active water leaks in various cracks or joints in below-grade structures. AV-333 does have the added benefit of containing dimethyl ketone (acetone) – a highly hygroscopic chemical able to attract surrounding atmospheric moisture and dissolve FOG (fats, oils, and greases) on contact to ensure good adhesion on various surfaces. It cures to form a resilient and flexible, yet tough, closed-cell foam. Certified for use in potable water.

• Midsize cracks or joints in concrete
• Stops infiltration in manholes, basements, retaining walls, etc.
• Use for applications that involve plastics
• Great for applications that are exposed to FOG
