AV-260 Fusion Grout
AV-260 Fusion Grout™ is a moisture activated MDI-based polyurethane resin. The water/moisture activation is a twostep chemical reaction and is catalyzed by mixing AV-261 Fusion AC™ with AV-260. Injected as a single component, AV-260 is designed to react quickly with moisture to seal active and potential water leaks in cracks or small annular spaces that are susceptible to wet/dry cycles and where flexibility is needed. AV-260 should always be injected into small, narrow, confined spaces to provide restricted expansion of the grout. AV-260 cures flexible and impermeable.
AV-261 Fusion AC is the catalyst designed exclusively for AV-260. Typically, one container of AV-261 is used per pail of AV-260 Depending on the desired reaction time, AV-261 may be doubled.
APPLICATIONS, FEATURES, AND BENEFITS OF AV-260:
- 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
- Free rise expands 1,500% – 2,500%
- Controllable reaction time by adjusting AV-261 Fusion AC volume
- Withstands wet/dry cycles
- Unique hydrophobic that cures flexible and closed cell
- Should always be injected into small, narrow, confined spaces to provide restricted expansion
