Rehabbing Aging Concrete Wastewater Infrastructure

Many of the country’s wastewater and sewer facilities are approaching the 50-100 year mark, and they must be continually fixed up to remain in use for a growing population. Yet municipal wastewater treatment centers, sewage systems, and vaults withstand some of the most severely corrosive environments in the water market, in addition to needing to pass increasing Environmental Protection Agency (EPA) scrutiny.

At industrial plants, the EPA furthermore enforces requirements to ensure that industries pre-treat toxins in their wastes to safeguard local sanitary channels and wastewater treatment plants.

These extreme wastewater plants must deal with environments ran under consistent chemical direct exposure and heavy abrasion that deteriorate concrete and rust steel in clarifiers, containment pits, anaerobic digesters, manholes, tanks, and other infrastructure assets.

A variety of aspects can trigger these structures to develop substantial cracks through which wastewater can escape (exfiltration), or groundwater can get in the wastewater system (infiltration). Leaks, cracks, and damage to existent coating systems not just top the list of problems in common upkeep and brand-new construction, they can also set off serious red flags if municipalities or commercial facilities are discovered in violation of EPA guidelines.

Luckily, polyurea coatings are proving ideal for wastewater infrastructure rehabilitation by presenting reliable, versatile, abrasive, and chemical-resistant waterproofing that not only bridges existing cracks but can elongate approximately 400% without cracking. Because they set and treat rapidly, and can be set up and used in a broad range of temperatures, they likewise decrease center downtime. Polyurea coatings supply robust, flexible waterproofing to bridge fractures and protect against future wear and tear.
