GeoSpray® Mortar: Culvert Lining
December 27, 2018
The town of Cary, North Carolina, is an affluent municipality located southwest of Raleigh. The town is near the center of the Triangle region, a commuter area consisting of three major universities: Duke, UNC and NC State as well as the technology hub located in Research Triangle Park. The housing development of Preston is located adjacent to the Prestonwood Country Club, where housing values range between $300,000 and $1M. Bridle Creek Dr. is the main entrance to the community, and the golf course with Bridle Creek crossing though a triplet of 52”-54” CMP culverts. In 2016, a section of one of these culverts collapsed, creating a sinkhole on the side of the road. The collapse was quickly repaired with a new section of CMP, but the community was concerned that the remaining CMP sections were showing corrosion in the invert and it would be only a matter of time before a more serious collapse occurred.
