SCS in conjunction with HDR worked with this particular hatchery that underwent a complete renovation of their facility. The project scope included the concrete rehabilitation and coating of the six raceways in the newly eclosed building. The coating specified for this project was PPC Coatings Polymorphic Polymers. This is a highly modified, rapid curing thermoset resin that can be applied to new and old concrete, steel, and fiberglass structures that require long lasting protection in severe corrosive and abrasive environments.
Some of the unique features of this resin follows:
After the concrete surfaces were abrasive cleaned and profiled, the coating was applied in 3 stages. First all the surfaces received a prime application of the resin. Next the surfaces received an intermediate build application to fill small voids and imperfections in the concrete. Finally a pigmented top coat of the resin was applied to smooth all raceway surfaces.
