Beulah Rd, VA
Concrete Clothâ„¢: Culvert Repair

Project Overview

As a result of periodic culvert inspections, the Virginia
Department of Transportation (VDOT) identified the existing
triple barrel steel plate culvert as requiring some action. Since
the roadway above the existing culvert had just been repaved
and new guardrail had been installed, VDOT wanted to avoid
total replacement at this time. The worst corrosion of the steel
was in the invert. In addition, the roadway had been widened
in the past and newer pipe was added outside of the original
culvert. Corrosion of the culvert was seen at the flow line and
the shape of the culvert appeared to be in its original geometry.
The roadway embankment was stable and there were no signs
of soil movement or cracking.

Solution 

Due to the access limitations, the VDOT maintenance crew
chose to install the Concrete Cloth™ GCCM perpendicular to
the direction of flow. This allowed the maintenance crew to
carry smaller pieces rather than installing long pieces parallel
to the flow. Water from streams was diverted through another
barrel and Concrete Cloth GCCM was installed in the dry area.
A power-actuated fastening system was chosen to secure the
Concrete Cloth GCCM to the existing plate structure because of
the thickness of the plate. This method led to a rapid installation
and the un-hydrated Concrete Cloth GCCM was installed in less
than a day. Strips of the Concrete Cloth GCCM were lowered
from the roadway above to the berm just outside the inlet of the
culvert using an excavator. VDOT had the choice of hydrating
the Concrete Cloth GCCM by either pumping water from the
nearby stream or bringing a water truck to the site.
