San Diego Utility Locating Projects that Penhall Worked On

Locate underground lines before core drilling

Penhall Technologies was hired to locate post tension cables in preparation for core drilling two holes on a roof. At the site, the analyst noticed the roof had a rubber like layer. He asked the client if the area could have the rubber layer cut away. After cutting the area, there was foam underneath. The analyst started to scan and found that the area was congested with post tension cable. The contractor then proceeded to map out another area to scan. The analyst marked all subsurface objects found. Out of the three proposed areas, the client used our scan site markings to pick the best two. The client performed the core drilling successfully.

Penhall locates utilities in an 8 mile path for Camp Pendleton

locate private utilities in San Diego CARecently, a general contractor  hired Penhall Technologies to locate all utilities in the dig parameters of an 8 mile path on the grounds of a Marine Corps base Camp Pendleton. The general contractor is installing a communications duct bank and wanted to know the location of all of the utilities prior to trenching for the  lines. Penhall came in after a previous locating company had been called out. Penhall located a total of 16 lines, unmarked by the previous company, preventing catastrophic damage to high profile utilities and saving valuable time. We used the SIR 4000 with a 400Mz antenna and the Electromagnetic Detection RD8000 unit to direct connect onto all the utilities in direct conflict with the clients dig parameters.
