The Problem and Flex-Seal Solution
An inexpensive and permanent method of sealing the grade adjustment ring area and joint sections in a manhole or catch
basin from the inside of the structure. This state-of-the-art method is packaged in a kit that anyone who is trained and
certified can install it.
The Manhole Problem
Engineers, contractors, maintenance staff, and rehabilitation experts know that over time their fine work from design to field
installation will fall victim to acids, salt, and ground movement, etc. Manhole structures will leak at the joints and at the grade
adjustment rings resulting in excess ground water infiltration. This will increase treatment processing costs and erosion in and around
the structure.
The Manhole Solution
Flex-Seal Utility Sealant® is an aromatic urethane rubber. Urethanes are noted for extreme toughness, elongation, abrasion resistance,
acidic resistance, and longevity. Sealing Systems, Inc. process allows a fast and simple method of sealing the adjustment ring area
and joint sections on any concrete structure. When properly installed, the adjustment ring areas and joint sections will not allow
infiltration and will not deteriorate from hydrogen sulfide or road salt.
