Manhole-Joint Seal Cut Sheet


WA-MH-JW Joint Wraps have a mastic base layer that adheres aggressively to concrete, and continues to “cold flow” at typical ground temperatures. Back filling actually increasing its bonding capability.




- The seal wraps bonding ability is further enhanced by compression bands. Tensioning ratchets allow the installer to position the wrap before back filling. Backfilling further compress the mastic under surface.

- A woven polypropylene internally laminated layer of high shear strength, increases puncture and shear resistance.

- Flexibility of the joint wrap will accommodate some settlement at the joint gap.

- WA-MH-JW exceeds ASTM C 877 (TYPE II) for RCP and structures.
