Epoxy Coatings Retention Pit July 28, 2021 by Administrator Retention Pit, MidWest – An engineer for a chemical plant in the Midwest was looking for a solution for somewhat of a fast track project that needed to be completed. The contractor had 2 weeks to place new concrete that could be coated after just a few days with a chemically resistant coating for a retention pit. – The concrete was enhanced with Vapor Lock 20/20 and under proper controlled ambient conditions, the contractor was able to install IMCO TECHNOLOGIES 700 series IMKOTE well ahead of the standard “28 days” required for unenhanced concrete.In fact, enhancing their concrete with Vapor Lock 20/20 kept them not only on, but ahead of schedule they were able to get this project completed a couple of days early.
