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 best digital GPR equipment available.
