The Problem & Infi-Shield Solution
The Problem
With the growth of sanitary and storm water sewers, concrete structures have become an accepted industry standard. They serve both to contain water within, and also to exclude unwanted water from entering. Routine maintenance cost to repair, upgrade, and extend systems is an ongoing expense. Construction methods have remained basically the same, with little progress made in countering the hostile, deteriorating forces attacking the structures. While the use of concrete products remains popular, the industry is slowly changing and adopting new ideas.
What to Fix
To maintain internal integrity, products to improve the joint seals between concrete sections, manholes, and adjustment rings, have been introduced - with mixed success. Butyl and rubber are commonly used in joint seals, whereas, mortar is used in adjustment rings to keep ground water from infiltrating. But, as mortar breaks up, the never ending maintenance cycle repeats. Therefore, if we could guard mortar from attack, and delay breakup, we could maintain structural integrity and extend the useful service life of the system.
What Happens
In a manhole or catch basin, the deterioration of mortar is affected by a variety of forces - freeze thaw cycles, exposure to water, acidic soils, chemicals, ground faults, traffic - creating soil movement and general exposure problems. In due time, as the mortar seal on the structure is breached, infiltration of ground water and siltation increases, adding both to the accelerating deterioration of the structure and to additional processing expense for the treatment facility. Until recently, no effective method existed for protection against this attack.|
The Solution
An external sealing system was developed by Sealing Systems, Inc., creating a protective rubber jacket, sealing the casting to the structure. This effectively eliminates infiltration and siltation through the adjustment rings, reducing the hydraulic loads on piping, pumping stations, and waste water treatment facilities. In addition, frequent and costly repair and maintenance is reduced, eliminating the sinking earth around manholes and catch basins. Expensive curb replacement, pavement, landscaping, and siltation clean-up is eliminated.
