SurSeal

Riser ring protection for manhole chimneys.

External Manhole Frame/Chimney Seal

SurSeal is an external manhole frame/chimney seal that provides a permanent, flexible, watertight seal between the manhole casting and the concrete cone. It combines the advantages of a mechanical seal with the added assurance of a pliable gasket. Its high performance, ease of installation, and low cost, makes SurSeal the right choice.

SurSeal is easy to install and designed for simple readjustment when/if grades are required. It requires no special tools, primers, or torches for installation. The same tool used to tighten pipe to manhole connectors and flexible couplings is also used to tighten the top and bottom bands of SurSeal.

SurSeal’s top band compresses the pliable rubber gasket component, uniformly filling the annular space and forming a gasket seal to the top, bottom and the outside edges of the frame’s base flange. The band’s “C” shape mechanically locks the seal on the manhole casting. The flat bottom band compresses the pliable gasket component against the top of the concrete cone, instantly filling any minor voids or irregularities. SurSeal meets or exceeds the material requirements for ASTM D 412 (Die C), ASTM D 816 (Modified), ASTM D 624 (Die C), ASTM D 2240, ASTM D 1149, ASTM D 573, ASTM D 1204, ASTM D 746, ASTM D 471 and ASTM E 96.
