GeoSpray® Culvert Invert Protection – Butler County, OH

WATER/WASTEWATER   STRUCTURAL STRENGTHENING

PROJECT OVERVIEW

The Ohio Department of Transportation’s (ODOT) Office of Hydraulic Engineering had interest in utilizing Concrete Cloth GCCM in a culvert lining/protection demonstration project. Concrete Cloth material would be used as a substitute to the ODOT standard practice of field paving an invert with 3-inchthick reinforced concrete. The Administrator for the Office of Hydraulic Engineering, Jeff Syar, led the efforts to locate a suitable project candidate.

A 114” x 77” corrugated metal arch culvert under SR 732 located south of Oxford, Ohio, was selected as a possible candidate. Contractor R.B. Jergens was under contract with the ODOT District 8 office to field-pave the invert. An inspection of the culvert by Milliken Infrastructure and District 8 personnel revealed that the minor deterioration and pitting of the invert made the culvert an excellent choice for Concrete Cloth lining.

SOLUTION

The District 8 office executed a change order to substitute the field paving with Concrete Cloth. Approximately 1000 square feet of CC8 fabric was placed in the lower third of the culvert along the entire 62-foot length. The lining process took place in May of 2016 and was completed in one week’s time by R.B. Jergens.

RESULTS

An inspection in 2017 revealed the Concrete Cloth lining is performing well. District 8 Culvert Engineer, Jeff Meyer expressed his satisfaction with the installation as well as performance of the lining, and will consider use on future projects.
