SurSeal is a high-performance watertight seal between the manhole casting and concrete cone. SurSeal combines all of the advantages of a mechanical seal with the assurance of a pliable gasket in a product that's cost-effective and easy to use.
SurSeal Chimney Seals are easily installed, without the needs for torches, primers or specialized
SurSealChimey seals work because the top band of the gasket adds compression to the inner rubber gasket material, uniformly filling the annular space between the frame and the cone. The resulting seal forms a watertight barrier around the top, bottom and outer edges of the frame's base flange. Our unique "C"-shape band mechanically locks the seal on the manhole casting for lasting performance, while adding additional compression instantly filling any minor voids or irregularities.
