Leaky roofs can be a hassle to deal with, but imagine the difficulty in addressing a leaking roof the size of one and a half football fields. Add to that situation a water treatment facility, and you have a major headache. Because water treatment plants are responsible for decontaminating their city’s water, it’s particularly important that outside water not infiltrate the facility. So, installing a new roofing system was of the utmost importance when the Midland (MI) Waste Water Treatment Plant management recognized that its aging ballasted roof was failing.
The facility’s existing ballasted roofing system consisted of EPDM rubber that had river rocks placed on top of it. As the system’s name implies, the rocks functioned as a ballast to keep the EPDM in place. Over time, however, the rubber had stretched and moved andstarted to pull apart, which ultimately led to the leakage problems the facility was dealing with at the time. The plant contacted SPRAYtight, Inc. to help them attain a watertight, seamless roofing system that would no longer pose a threat to the facility’s sensitive environment.
