Blackhawk™ Hawk-Seal
Butyl Rubber Sealant
| Blackhawk Hawk-Seal is a high-tack butyl rubber compound, used to seal the joints of underground concrete structures such as box culverts, manholes, concrete pipe, septic tanks, utility boxes and vaults. It comes in roll form and functions as a seal against infiltration and exfiltration. The high grade butyl content allows for year-round, consistent sealability. Composed of no asphalt, Blackhawk Hawk-Seal provides a special high-tack feature only found in butyl. |
