Preservation of wastewater treatment assets and the evolution of the coating options required to mitigate the severity of the exposure environment, are giving coating contractors pause to examine alternative means of application. By expanding application versatility, the coating contractor will be able to compete across the range of preservation options.
Reinforced concrete is the most common building material in water and wastewater treatment facilities. It is very common to see unprotected concrete in severely corrosive environments or corroding reinforcing steel that has been exposed due to construction defects or coating failures. The decision to coat new and existing concrete structures can be very difficult for owners due to the cost, turn-around times for putting structures back into service, and lack of confidence in certain protective coatings.
