Tucson Prviate Utility Locating Projects that Penhall Worked On

Locate gas lines for private residential property before installing new patio

locate gas utility at private residencePenhall Technologies was hired by a Tucson, AZ homeowner as his private utility locator. When the client booked the locating service, he mentioned that he needed to locate a gas line in his backyard prior to installing a new flagstone patio. Our analyst arrived at the client’s home and used the GSSI GPR 400MHz antenna. This equipment resembles a cart, and it is ideal for tracing underground utilities. The analyst proceeded to trace and mark the gas line, ensuring safety for our client’s family and home.

Before boring, ensure safety by locating utilities and underground storage tanks

Penhall Technologies was hired before boring ten locations by a client in Tucson, AZ. Our GPR analysts detected the locations of large, underground storage tanks using the GSSI 400MHz antenna. Besides locating underground utility lines, the equipment is excellent at picking up underground storage tanks and voids. The analysts located and marked the location of the tanks, which  allowed the customer to safely and confidently proceed with the boring.

Identify all underground utilities before digging trenches

locating utilities before trenchingPenhall Technologies was hired at a job site in Oro Valley, AZ. We often get jobs outside of our area of Tucson. This is not a problem to our analysts, they are ready to deliver accurate services in any area. For this particular site, our analyst used the Radio Detection 7100 (pictured) to identify all underground utilities. This equipment is used for locating utilities. However, it doesnt use GPR, it uses electromagnetic fields to locate any underground lines. The client mentioned that he wanted to bring a private utility locator prior to  digging trenches for new plumbing. All utilities located were marked and a written field report was provided to the customer for documentation and reference when trenching.
