GEOWEB® Geocells for Load Support Application

Project Name: Wawa Convenience Store at Prosperity Road

Project Location: Virginia Beach, VA

GEOWEB® Load Support System creates a vegetated access road around BMP Detention Pond

PROJECT BACKGROUND

A newly constructed Wawa Convenience Store, on the corner of General Booth Boulevard and Prosperity Road in Virginia Beach, shares a Best Management Practice (BMP) detention pond with the Prosperity at the Pines housing development. Part of the new construction project included building an access road around the BMP pond that would allow for occasional vehicular traffic to maintain the pond.

A VALUE ENGINEERED SOLUTION: VEGETATED MAINTENANCE PATH

The Wawa Development Project initially specified a concrete block matting for the maintenance path, which would be very costly and not aesthetically pleasing. Colonial Construction Materials, a local material supplier, recommended value engineering the Presto Geosystems GEOWEB® Vegetated Load Support System in lieu of the concrete block mats.

The Wawa project owners, engineers, and Colonial Construction Materials reps worked with Presto Geosystems’ engineering team to provide a customized project evaluation for the BMP vegetated access road—which was approved for use by Kimley-Horn.

The approved design for the maintenance path specified the GEOWEB GW30V6 (the mid-sized cell, 6-inches deep) filled with engineered infill—a mixture of topsoil and crushed aggregate. The engineered fill would provide load support for the maintenance equipment while supporting vegetation growth. The GEOWEB Geocell sections were connected using ATRA® Keys and secured with ATRA® Anchors.

Aesthetic Alternative to Hard Pavements

The GEOWEB Grass Porous Pavement System is designed to handle infrequent loading demands, while protecting the turf from damage and limiting concentrated rutting.

Grass-covered pavements constructed with the GEOWEB system and native granular soil are an attractive, functional, and cost-effective porous pavement system.
