Water Problems Like Those in Flint, Michigan Could Become Widespread
Cities across the U.S. are not keeping up with infrastructure maintenance.
The water crisis in Flint, Michigan was caused by aging pipes. Eric Scorsone, an economist at Michigan State University who has followed the case, says Flint may be the “canary in the coal mine” signaling more problems to come across the country. “Flint is an extreme case,” he said in a July 29, 2015 article in The Atlantic, “but nationally there’s been a lack of investment in water infrastructure.”

PolySpray Rescues a 214ft. Culvert Under I-70
When a Northwest Ohio 11'7" x 7'5" structural plate storm culvert under I-70 needed repair and rehabilitation, replacement was not an option. The selected repair system or lining had to be applied in situ, and was required to eliminate corrosion, maintain hydraulics and preserve the existing structural integrity. ODOT decided to repair the storm culvert using PolySpray SS-100, a spray applied resin system.
The scope required the rehabilitation of approximately 214 feet of pipe arch. The contractor removed all debris, prepared the surface with an abrasive blast, and sprayed the pipe arch with PolySpray SS-100.
The rapid-setting, semi-structural, monolithic coating provides moderate structural support to host the structure, as well as excellent resistance to incidental chemical exposure. This lining system will extend the life of the pipe arch, did not impede any highway traffic, and will not hinder hydraulic performances.
