Purethane^® coatings hold up well under the adverse conditions presented by sewage collection and treatment systems. It is widely used to line existing manholes over brick and concrete as well as steel and as coating for sewage treatment plants.

Purethane^® solves the deterioration problem caused by hydrogen sulfide and microbiologically induced corrosion (MIC) in sewers, manholes and sewage treatment plants. Applied to existing structures deteriorated by hydrogen sulfide gases, the remaining concrete is protected from further corrosion. Deteriorating sewer trunk lines can be reclaimed by lining with Purethane^® .

Purethane^® will provide a lasting protective system to new concrete structures and concrete pipe. Typical structures include Bar Screen Area, Grit Chambers, Primary Clarifiers , Aeration Tanks, Digester Roofs, Gas Holders,  Sludge Processing, Waste Tanks And Ponds.

Purethane^® 386/9000 is approved by the Los Angeles Bureau of Engineering for coating of sewage treatment systems.

The U.S Environmental Protections Agency, in a 1978 study, found that Purethane^® 386/9000 alone, of all materials tested showed “no defects” in all tests for materials for Oxygenated Wastewater Treatment Plant construction.
