Radio Detection and GPR used to locate electrical lines, grade beams, and footers

The customer was renovating an existing restaurant and needed to locate live electrical lines under the concrete slab. An RD7100 utility locating wand and transmitter were used to locate the electrical lines throughout the building.

Penhall Technologies also used ground penetrating radar to scan for grade beams and footers.
