Mar Mac SurSeal...

External Frame/Chimney Seal...

SurSeal is a high-performance watertight seal between the manhole casting and concrete cone. Our state-of-the-art technology 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.

	Easy-installation
	No primers, torches or special tools needed
	Simple readjustment to accommodate grade changes

How does it work?

The top band of the gasket is designed to add 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. Our high-performance seal requires no primers torches or special tools to create a watertight barrier.

The securing band adds additional compression instantly filling any minor voids or irregularities.
