Noble County, IN
Concrete Cloth™ GCCM: Culvert Invert Lining

Project Overview

The invert of a 12’ diameter CMP culvert in Noble County, IN, was experiencing minor pitting and rusting. The Noble County Highway Department needed a preventative solution to protect the invert from further abrasion and deterioration. The Highway Department wanted to make minor repairs instead of waiting for the culvert to get to a state beyond repair where replacement or major rehabilitation were the only options.  Milliken Infrastructure provided recommendations for the use of Concrete Cloth™ GCCM.  A thickness of 8 mm (CC8) was chosen for the project.  Milliken assisted with the identification of the material quantity and offered on-site installation assistance for the job.

Solution

The Highway Department attended a presentation on Concrete Cloth at the 2017 Purdue Road School and was intrigued by the application of the material. Compared to Concrete Cloth GCCM CC8, culvert replacement and concrete paving of the invert are costly options. With Concrete Cloth, the invert could be covered by county crews who received on-site installation assistance from a regional manager at Milliken Infrastructure. Before the Concrete Cloth was installed, the culvert had to be cleaned of all silt, and minimal voids in the invert had to be sealed with concrete to fill places that were rusted through completely.
