Heather Gardens Association of Aurora, Colorado

When Heather Gardens Association of Aurora, Colorado needed to add a guard rail to the edge of a parking garage without hitting any post tensioned cables or rebar they contacted GPRS, Inc of Denver, CO. The guard rail was to be anchored to the side of the structure at 4 inches below the surface. Thus they contacted ground penetrating radar specialists, GPRS. This is an ideal application for ground penetrating radar as PT Cable and rebar locating are GPR specialties. GPRS, Inc. from Denver, CO took the call and mobilized to the site.

On site GPRS was able to identify all of the post tensioning cables and rebar quickly and accurately. The cables were found to be at a depth of 4 inches below the surface, exactly the depth that the bolts for the guard rail would be inserted. GPRS was able to prevent penetration into the PT-Cables. They marked all of the cables on the surface with depth indications to the top of the rebar or cable. GPRS then collaborated with Heather Gardens as to the best places to install the rail to avoid striking a cable. The project was a success and radar once again proved its usefulness on concrete for locating rebars and post tensioned cables.
