Manhole Chimney & Joint Sealants

Leaks through the joint between the manhole frame and the chimney is a common source of infiltration, but are seldom included in a rehabilitation project or repaired at all. We offer easy-to-use flexible epoxies or an EPDM rubber seal that will quickly and permanently stop infiltration through the manhole chimney joint. These products can also be used for sealing joints in precast structures.
