Video: Locating PEX tubes with GPR

Using ground penetrating radar (GPR) to scan a concrete slab and locate radiant floor heat PEX tubing. Results are marked directly on the concrete with this real-time 2D method. Rebar is also marked to help with drilling.

GPR is ideal for locating PEX tubes in concrete regardless if they are filled with air or water. X-ray technologies aren’t feasible for these slab-on-grade challenges. Accurate results with GPR for PEX are dependent on operator expertise and equipment quality. Concrete GPR LLC technicians have over a decade of experience, and use the most current digital GPR equipment available.

Locate PEX Tubing in Concrete

Locating PEX tubes in concrete is just another day at the office for us. On this project, we marked up the location of all PEX tubing in an 18′ x 60′ area. The tube layout is great. It wraps around some existing equipment from the original installation with unusual bends and whorls. Everything went great […]

Backfill Mystery

We were called to ensure the area was clear of high voltage conduits prior to excavation. With our expertise and cutting edge GPR imaging equipment, it should have been a quick one-and-done. Years of experience, however, has taught us to never underestimate a project, especially a very old concrete slab. The good news: there weren’t any […]
