Concrete Cloth™ Slope Protection – Cumberland County, OH



The North Carolina Dept. of Transportation (NCDOT) Bridge Maintenance Division 6 had a major erosion problem at the bridge piles underneath I-95 at Highway 87 in Cumberland County, NC. The bridge deck above was leaking water at the joint, cascading down and eroding the slope that protects the concrete bridge piles. The NCDOT was constantly repairing this area so it decided to use Concrete Cloth GCCM to prevent further erosion and limit maintenance.


Traditionally, a thin, poured concrete slab called slope paving, or riprap placed on top of a geotextile to protect the existing slope would have been installed. Vegetating the slope was not an option because of the the low sunlight conditions.


NCDOT chose to install Concrete Cloth GCCM as an alternate to riprap. Using Concrete Cloth GCCM allowed the NCDOT to utilize its own maintenance crew and avoid having to use any large equipment to protect the slope. The Concrete Cloth GCCM was keyed into an anchor trench on the perimeter of the slope protection and staked down with 12” pins with washers around the circumference of the piers. Concrete Cloth GCCM was easy to cut with simple hand tools around the circular piles. This area was later grouted. The installation was completed in approximately two hours.
