Blackhawk Hawk-Seal
Butyl Rubber Sealant
| 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. Hawk-Seal 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, Hawk-Seal provides a special high-tack feature only found in butyl. |
