Biloxi Utility Locating Projects that Penhall Worked On

Ground penetrating radar used by private utility locator to determine multiple layers and thickness of each layer

utility locating to determine asphalt, concrete, and sand layersRecently, Penhall Technologies was hired at a job site in Pascagoula, MS. The job consisted of performing GPR (ground penetrating radar) scanning for an engineering company. The analyst used the GSSI 400 MHz antenna and utility cart (as pictured). The purpose of the scanning was that the company needed to understand what utilities were under asphalt, concrete, and sand layers in a 100 x 10 foot area about eight to ten feet deep. Our expert analysts were able to approximate the thickness of each asphalt, concrete, and sand layer. This is because the moisture levels were controlled and the spacing of the rebar allowed the analysts to gather sufficient information. After the analyst completed the scanning , he generated a report of the findings for the engineering company. This serves as reference when doing any kind of excavating in the scanned areas.

Locate utilities using GPR scanning for military base

locate utilities at military base A general contracting company hired Penhall Technologies to perform ground penetrating radar scanning . The job location was at a local military base. Our analyst used the GSSI 400 MHz antenna (pictured) and a utility scan cart to locate the underground utilities that were about 3 feet deep in a 240 x 90 foot area. After scanning, the analyst marked the utilities found with the designated color.

Locate underground utilities before starting a home project

A home owner in Biloxi contacted Penhall Technologies to do a private utility scan for a driveway extension. The customer’s driveway had become cracked and uneven. For this reason, they wanted to demo the old slabs and extend the driveway around the side of the garage. Our analyst located the utilities using an RD 7100 hundred wand and transmitter. Some of the utilities were able to have currents induced on to them from where they entered the residence, which allowed our analyst to get good strong signals on the utilities giving him accurate locations. He found three utility lines running through the area in question. The client was able to have them relocated before beginning excavation of the site.
