Dallas Concrete Scanning Projects that Penhall Worked On

GPR used in private residence to locate a leaking pipe

Recently, a private homeowner hired Penhall Technologies to scan his driveway to map out the extents of a void he’d discovered. The homeowner needed to have as much information as possible in order to decide how best to solve this issue. Our Dallas based analyst was able to use a GSSI Mini XT to quickly establish and mark the extents of the void, and identify the leaking pipe that was causing it.  This kept the homeowner from having to remove more of the driveway slab than was absolutely necessary, thus saving time and money.  The project goes to show that no job is too big, or too small for Penhall Technologies to complete.

Locate electrical conduit through under side of a concrete ceiling

scanning ceiling under side of concrete for electrical conduitPenhall Technologies was recently hired at a location in Dallas, TX. The client requested for the analyst to use ground penetrating radar (GPR) to scan nine 3′ x3′ areas along the ceiling of the building. The analyst used the GSSI mini XT to locate the electrical conduit in the concrete. Then, he properly marked the nine areas.

Locate post tension cable using GPR

Concrete scanning to find and locate post tension cablePenhall Technolgies was hired at a jobsite in Fort Worth, TX. Once the analyst arrived on site, he performed a concrete scanning service of three areas for openings. The areas consisted of measurements of 8′ x 8′ x 8”, 10′ x 20′, and 10’x 25′ x 8″. Additionally, the analyst scanned a 5′ x 5′ x 6″ thick area on a gym floor. The client was trying to confirm if the pattern on the floor was post tension cable. After scanning, the analyst marked the post tension cable with chalk.

Ground penetrating radar used to locate conduit in concrete slab

GPR scanning to locate and mark conduit in concrete slabFor this project, Penhall Technologies’ analyst traveled up to Pryor, OK. Sometimes, a request to perform concrete scanning in a different state comes in. This is not a problem for our analysts, they make sure to complete the scanning service in a timely and accurate manner.  This project was no exception. After arriving on site, the analysts used GPR to thoroughly scan the area. They located conduit on the concrete slab.
