And so when the client needed help with planning the washout pit for their oil-waste-carrying trucks, they didn't just assume that the typical HPDE solution was the right one. In fact, Rogers commented that the HPDE process is "risky at best," which meant they'd be working on a diferent solution. "With the Texas regulatory body of the Railroad Commission (RRC) handling the construction of these struc- tures, RROC felt that the best construction method was to utilize the concrete structure of the pit as the secondary level for containment and the coating as the primary portion," Rogers continued. "Tis satisfes the RRC's requirements as stated in the permitting process for these structures without the inher- ent problems presented with installing a liner underneath the concrete structure." Terefore, the coatings were crucial. For this project, the containment would need to be able to withstand truck trafc, protect against abrasive slurry, and resist chemical assault. Tey also needed to make sure to use a product that would continue to protect the concrete well into its service life because "the customer also needed a product that was impact-re- sistant, so the tools and hose connections that would be utilized [once in service] wouldn't damage the coating if dropped," Rogers explained. And on top of that, "because of the chloride content of the wastes, an additional beneft of the coating was the prevention of concrete spalling." Te coatings crew knew it would be a tall order from the start, for, as Rogers explained, "saltwater eats up concrete like nobody's business." And fnally, he said, "because the inputs to the pit are so diverse in nature, the need for a coating that could provide protection across a broad spectrum of materials Th e crew s tar ted by ab ra si ve bla s ting th e subs trate.
