Key Benefits

Provides watertightness, while having the flexibility to allow differential movement of the manhole sections caused by ground movement and frost lift.

Reduces excess clearwater entry into sanitary sewer systems by stopping manhole joint leakage, thereby providing more system capacity and reducing treatment and pumping costs.

Mechanically installed to the inside of existing manholes, no unknown qualities of chemical grout or chipping and patching to wonder about.

Reusable-can be removed and used elsewhere if needed.

Constructed of the same high quality materials as our Internal and External Chimney Seal for a long service life.

Materials conform to the physical requirements of ASTM C-923, ASTM A-240 Type 304, & ASTM A-479 Type 304.

Available in 42", 48", and 60" diameters.
