Locate water lines for private residential property to avoid damage when digging

Locate water lines at a private residence from the basement to the courtyardFor a private property in Durham, NC, Penhall Technologies was asked to locate water lines from the basement to the courtyard.  Our analyst scanned approximately 30 linear feet to locate the lines, which helped the homeowners avoid damaging any pipes when digging for a small renovation.

Scan to identify bonding and grounding loops for pool at apartment complesOur local GPR analyst scanned at an apartment complex in Durham to locate the bonding and grounding loops for a pool.  When the pool was installed, the contractor did not have the proper inspection, so the complex managers asked us to come in and locate the loops to prove that they were present. The customer passed inspection without any costly removal and reinstallation.

Penhall uses Radiodetection (RD) technology to successfully locate conduit lines despite saturation in soil

Radiodetection RD used to locate underground conduit power linesPenhall Technologies was hired to perform utility locating for a large solar company in Snow Camp, North Carolina. The job site was located on a solar energy farm, where hundreds of energy-producing panels fed into 4 transformer units via underground conduits. Concerns arose when the concrete slabs that supported these transformers had begun to sink. They required multiple access points underneath the slabs where they could stabilize the foundations, which meant digging into conduit filled earth. To ensure their safety and minimize the risk of damaging power lines, they contacted Penhall to pinpoint where the conduits were running. The initial attempt at locating these hazards using the SIR 4000 utility cart was ineffective, as rainfall from the previous week left the soil too saturated for the GPR signal to penetrate the ground. However, another piece of equipment, the RD 1700, was successful in detecting conduit lines by identifying peaks of electrical current coming from below. Despite the setback brought on by the weather, we were still successfully able to call this job a success.

Locate and mark utilities to ensure safety when performing a building demolition

locate utilities to safely perform demolitionPenhall Technologies was recently given the opportunity to complete utility locating for a construction firm in Clayton, NC at a site located on a junk yard. Their construction plans included the demolition of two buildings on the property and the addition of a new one. Before beginning their work, the client was concerned about striking any private utility lines leading into or running along the existing buildings. Additionally, the construction of a new structure would require electricians to tie into a main power line. Penhall was effectively able to locate subsurface hazards near the current buildings, as well as the proper electrical line to be tied into. This contractor may now rest assured that their project will continue on time, and that safety risks will be diminished.
