GeoSpray® Geopolymer: CMP Culvert Repair

Project Overview
The North Carolina Department of Transportation (NCDOT) was looking for an initial challenging project to complete in North Carolina with GeoSpray mortar. Along the banks of the Roanoke River in the city of Weldon, NC, the NCDOT was faced with significant issues of culvert failure and bank erosion that were beginning to threaten private homes. A 108-inch diameter CMP pipe approximately 85 feet in length connects incoming streams to the Roanoke River. The pipe is buried 25 feet below ground under the only access road to a commercial water treatment plant and a cotton and soy bean farm. The NCDOT had already repaired and stabilized the bank on the river side of the culvert with a steel embankment and was now confronted with the problem of extending the life of the failing culvert.
