GC Mapping provides professional and responsive underground utility marking. We provide level B loacting servicing and also trace storm structures to blind junction boxes. We can locate PVC for septic lines and roof drains where accessible. Sketches are always provided depicting utilities found.

​

*Level B: dispense paint and/or wire flags (surface marking) along traceable utilites.

​

*GPR (ground penetrating radar) equipment allows GCM to identify the depth of buried pipes in proper soil conditions
