Manholes
Manhole rehabilitation now easier than ever
The United States Environmental Protection Agency estimates that there are 26 million manholes in the United States alone. These manholes vary in size, shape and construction, but one thing that many of them have in common is that they are beginning to deteriorate. For a long time, this was a major problem for cash-strapped municipalities. When you add in the headache of rerouting traffic and the service disruptions caused by manhole replacement projects, it is easy to understand why they were often put on the backburner.
Fortunately, advancements in polyurea technology mean that manhole rehabilitation is not only possible, it is also easier than ever to prolong the life of aging sewer infrastructure. This is increasingly important, because if left unaddressed, manhole inflow and infiltration, corrosion and deterioration can lead to major challenges down the road.
Manhole rehabilitation without traffic or service disruptions
OBIC’s line of manhole lining systems and sewer lining coatings are made of a flexible polymer that is spray applied and cures in minutes. That means your next manhole rehabilitation project will require minimal traffic or service disruptions. Additionally, unlike the alternative rigid products, OBIC’s manhole lining system will not crack under the pressure of heavy traffic or extreme temperature changes.
No two manhole rehabilitation projects are the same
At OBIC, consistency is a word we say frequently. After all, our customers depend on consistent quality and services for all of their wastewater rehabilitation needs. What keeps our jobs interesting is that, though our products are predictably effective and long-lasting, no two manhole rehabilitation projects are ever the same.
Designed to be flexible enough to withstand the demands of the host structure, OBIC’s manhole rehabilitation products are designed to extend the life of the manhole by 50 years or longer. We are so confident in our products, that they also come with a 10-year warranty when installed by a certified OBIC installer.

Schedule a customized product demonstration
OBIC manhole rehabilitation lining systems offer a high-quality, cost-effective alternative to the replacement of the structure. Product demonstrations can be conducted in an optional lunch and learn format, and we encourage you to invite anyone interested in learning more about OBIC products. All we need from you is a location and a manhole no deeper than 8-9’ for the demonstration. We will provide the refreshments.
