Three core services across San Luis Obispo County: underground utility locating (including private utility locating and marking), ground penetrating radar (GPR) for concrete scanning and subsurface imaging, and CCTV drain inspection with sewer camera and sonde locating.
Private utility locating is the process of detecting and marking buried lines that 811 / DigAlert doesn't cover — the private utilities on your property such as lines past the meter, power to detached structures, irrigation, propane, and private sewer laterals.
No. 811 / DigAlert only notifies public utility owners to mark lines in the public right-of-way. Private lines on your property are the owner's responsibility — that gap is exactly what we fill.
GPR images the inside of concrete and soil without damaging either. It locates rebar, post-tension cables, conduit, and voids before cutting or coring, and can find non-metallic pipe such as PVC that electromagnetic locating can't detect on its own.
A CCTV drain inspection sends a waterproof video camera through a sewer lateral or drain line to show the real condition inside the pipe — blockages, root intrusion, cracks, offsets, and bellies — without digging. A sonde in the camera head lets us mark the problem location from the surface.
