PROJECT BACKGROUND

In Portsmouth, New Hampshire, the AC Hotel installed two new concrete pump stations that needed to be lined with a protective coating. A&W Coatings was contracted to apply Warren Environmental’s (Warren) 301-14 high-performance epoxy coating throughout both pump stations. This job was to be performed on the same day the stations were backfilled. 

A&W’s crew faced multiple challenges throughout the project. The first obstacle was working simultaneously with the installation contractor. A&W had to wait for the contractor to complete filling at least one pump station with concrete before they could apply Warren’s epoxy. Additionally, the work areas were in tight alleys, making movement difficult.  

Once the concrete dried, A&W water blasted the surfaces using between 4,000 and 6,000 pounds per square inch (psi), followed by acid etching. Our crew spray-applied 150 mils of Warren’s 301-14 epoxy to each pump station for a total of 304 square feet.  

With Warren’s epoxy coating the pump stations, these newly installed assets will be safe from corrosion and other environmental damage for many decades to come.
