COATINGSPRO MAY 2015 73 using geotextile fabric and polyurea to get the pipe stands totally covered and tie those in to both the pipe stands and concrete. We had to abrasive blast all the pipe stands, too, and coat all those so the fabric encapsulated around the pipe stands would adhere." Another major challenge to the project was the weather. "It's outdoor coating, so we're very weather dependent," Hofman said. "If the ground is wet and the geotextile gets wet, we can't perform any work." A few times, coming storm clouds raised the crew's blood pressure. " We d id have a couple of c lose encounters w ith some rain," Hof f man said. " T he stor ms were coming up to a point where they were w ithin 5 mi les [8 k m] of our location, and we wou ld have had to cut out the ex isting geother ma l fabr ic a lready laid dow n and lay dow n more fabr ic or wait for it to dr y out." But waiting for the fabric to dry would likely be a losing proposition. "Because you've already built this wall trenched in 10 inches [25 cm] to the ground, if water were to get inside the containment, it would hold the water; it wouldn't drain of," Hofman said. T he combination of weather and abrasive blasting that was ta k ing mu ltiple days made Hof f man wor r ied about f lash r usting. So what d id he do to prevent it? "Prayed," he joked. "It 's outdoor coating , so you can't control it. You just have to go w ith the weather and schedu le the best you can. A nd if you k now a lot about the oi l industr y, they don't like waiting on any thing." Luckily, they did not have to wait long. Te crew fnished the job within a month with excellent results.

CP the metal and then continued spraying over the 1-foot [ 30 cm] textile fabric." "Imagine a wall, and you've got fabric going up 1 foot [30 cm] at the bottom of the wall that's draped over onto the ground. We sprayed the wall itself, rolled the fabric up, and it bonds the wall to the fabric. Ten we sprayed from the foor all the way up to the top of the wall." Te crew used 3M half-face masks with organic flters for the spray application, and they always wear fre-retardant clothing when on locations, Hofman said. Tey also wore steel- toed shoes, goggles, safety glasses, and ear plugs along with H 2 S monitors. Containment Predicament T he job required a lot of tricky navigation around 112 total pipe stands. "W hen you're doing the geotextile fabric and have all those pipe stands, we had to cut all the fabric at diferent angles, much like laying concrete down," Hofman said. "A lso, we're "You have containment in case there was ever a failure with those pumps," said Aaron Hoffman, technical sales director for Lewis Concrete Restoration Corporation, which has been in the water/wastewater coatings/lining market for 20 years. Luckily the weather didn't cause any trouble for the crew. "It's outdoor coating, so we're very weather dependent," Hoffman said. "If the ground is wet and the geotextile gets wet, we can't perform any work." With the secondar y containment completed, the oil facility was now able to be sure that the saltwater produced with the oil gathering was disposed of properly and not contaminating the ground.
