Montgomery Utility Locating Projects that Penhall Worked On

Locate all utilities to ensure safety when excavating

Locating all utilities before excavationA customer in Montgomery, AL recently hired Penhall Technologies as his private utility locator. The client needed to identify subsurface utilities such as water, gas, sewer, and electrical before excavation could begin on a new construction project. Penhall Technologies’ GPR analysts arrived at the job site, and used two utility locating equipment (as pictured). They used GPR with the GSSI 400MHz antenna, and used the RD7100 with radio detection technology. Analysts always have both equipment on hand to  locate and mark identified utilities to maximum accuracy.

Detect subsurface utilities and storage tanks for a gas station

Detect subsurface utilities and storage tanksPenhall Technologies was hired to locate underground utilities at a local gas station in Montgomery, AL. The service was done prior to an installation of a new perimeter fence. By conducting the utility locating, the project remained on schedule. Ultimately, the gas station only had to be closed for 12 hours during non-business hours.

Ground penetrating radar used to locate and mark electrical and gas lines

Before trenching began, the homeowners called Penhall Technologies to perform underground utility locating on a 20’x30′ area. The analyst marked water and electrical lines and provided the homeowner a written field report to share with the pool company. This ensures safety for the client and those working on his project.
