How Do OBIC Products Address Needs of Culvert Lining, Manhole Lining, and Water/Sewer Lining?

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 jobs are ever the same.

A municipal and industrial water and wastewater systems maintenance company, OBIC specializes in providing an alternative approach to everything from wastewater structure rehabilitation to potable water tank rehabilitation. Made of a flexible polymer that is environmentally friendly, OBIC coating systems are spray applied, making them ideal for structures of all shapes and sizes. Additionally, unlike alternative rigid products, OBIC’s flexible polymers won’t crack under the pressure of temperature changes or heavy traffic.


Manhole Rehabilitation

The United States Environmental Protection Agency estimates that there are 26 million manholes in the U.S. These manholes vary in age, construction and deterioration. Some examples of this variation include


  • Precast concrete
  • Cast-in-place concrete
  • Brick
  • Concrete block
  • Stone

Size and shape

  • Various diameters: 3’, 4’, 6’, 7’, 8’
  • Various depths: some more than 100’ deep
  • Various shapes: round, oblong, rectangle, bell-shaped, offset cones, eccentric cones


  • With and without steps
  • Pipe protrusions
  • Drop bowls
  • With and without benches
  • Surcharged manholes
  • Gravity flow manholes

Wastewater Treatment Plants

The American Society of Civil Engineers reports there are 14,748 wastewater treatment plants in the U.S. Although there are dozens of different designs for wastewater structures, each one shares the following characteristics, and most will benefit from coating/lining to extend useful life.

  • Headworks
  • Grit chamber
  • Screening system
  • Aeration or oxidation basin
  • Primary, secondary and perhaps tertiary clarifiers
  • A filter system
  • Digesters
  • Chlorine contact chamber
  • Biosolids storage

Lift Stations

Depending on typography, lift stations are necessary to supplement gravity sewer systems. Examples of variations that OBIC installers have encountered include

  • Precast concrete
  • Poured-in-place concrete
  • Concrete block
  • Brick
  • Steel
  • Hundreds of different sizes, shapes and depths


Stormwater Systems

The American Society of Civil Engineers reports that there were 1,600 communities with a stormwater system separate from the wastewater system. These structures, especially in northern areas of the country, become eroded by road salt or ice-melting chemicals. Stormwater systems, other than the obvious concrete or corrugated steel culverts, utilize

  • Concrete catch basins
  • Curb inlets
  • Sometimes include manholes that are the same as a wastewater manhole

Drinking Water

The American Society of Civil Engineers estimates 155,000 active public drinking water systems. These systems all have

  • Concrete or steel storage tanks
  • Precast concrete
  • Fiberglass or steel pump stations

Thousands of configurations all with one solution

There are thousands of different configurations, sizes, shapes and materials of construction. That is why OBIC products were designed with the understanding that no two jobs are the same.

Every product that OBIC offers is backed by our commitment to providing high quality, cost-effective water and wastewater rehabilitation solutions. Our products are backed by a team of chemists who employ rigorous testing that ensures consistency and quality. Additionally, third-party testing has proven that OBIC products are physically stronger than similar products available on the market.
