Has What It Takes Above The city of North Lauderdale, Fla., hired local coatings applicator ZTI to coat the interior of its 25-year-old tank. Holding 32,000 gallons (121,133 L) of water meant it was going to be a big job! T he cit y of Nor t h Lauderdale, Fla., has a lot to celebrate in 2013. It 's t he cit y's 50t h a nniversa r y, and, to commemorate, it's celebrating 50 fun things to do throughout the year. North Lauderdale is holding severa l f ishing derbies, ack nowledging residents who have lived in town for more than 30 years, and hosting a golf tournament, just to name a few of the events. But there's one thing notably missing from this list. At over halfway through its 50th year as a city, North Lauderdale could also be celebrating the rehabilitation that was completed on its Water Facilities Public Works Plant. With their water sourced from the Biscayne Aquifer, the 42,000 residents of North Lauderdale aren't immune to water rules. Not only does the city have year-round water restrictions, but it also has guidelines for storing water during storms. Now, at the start of the 2013 hurricane season, it's important that the residents of North Lauderdale have enough drinkable water to supply each By stePhAnie MArie ChiZik Photos Courtesy of Zti, llC house member with 1 to 2 gallons (4–8 L) per day. Without the help of Zack Tanner, president of ZTI, LLC, and his coatings crew, this may not have been possible. honeyCoMB hoMe The 25-year-old tank at the Water Facilities Public Works Plant badly needed repairs. The concrete tank, which holds 32,000 gallons (121,133 L) of water, was deteriorating. It needed to be abrasive-blasted, repaired, and then coated. And everything needed to adhere to the strict guidelines regarding potable water tanks so that the city of North Lauderdale could continue to have safe drinking water. For Tanner and his crew, led on site by business partner Joseph Keough, their role started after the city was done abrasive-blasting the 3,000 square feet (279 m²) of concrete. Unfortunately, this is where the ZTI crew encountered its two glitches of the project. The abrasive-blasting left the tank with an extreme amount of bugholes, which created honeycombing. This poor condition was a complete surprise to the coatings crew, although what else could they do but dive right in and start fixing it? Over two and a half days, the six-man crew began by working to add a skim, or parge, coat to the tank. This was done to give the substrate a smooth surface. July 2013 g www.coatingspromag.com 63
