AV-248 Flexseal

AV-248 Flexseal is a moisture activated, MDI-based polyurethane resin whose chemical reaction is catalyzed by mixing AV-249 Flexseal AC with AV-248. Injected as a single component, AV-248 is designed to seal active and potential water leaks in various cracks and annular space where flexibility is needed, but is susceptible to wet/dry cycles. AV-248 cures resilient, impermeable, and flexible.

AV-249 Flexseal AC is the catalyst designed exclusively for use with AV-248 Flexseal. Typically, one container of AV-249  is used per pail of AV-248. Depending on the desired reaction time, AV-249 may be doubled. 

APPLICATIONS
• 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
