Underground utility locating services for landscaping

A landscaping company hired us for our underground utility locating service. The client was installing irrigation lines in the outfield of 6 softball fields, and needed to locate any utilities to perform the installation safely. Our analyst used the RD7100 and GSSI Utility cart with the SIR 4000. He found and marked both irrigation and power lines with paint and flags.

GPR and Radio Detection used to identify conduit and utilities underneath slab

concrete scanning to find conduit and utilities under slabPenhall Technologies was contacted to scan 4 trenches for shallow conduits and utilities prior to saw cutting. The contractor had noted electrical conduits along with drain lines running just under the concrete slab. Penhall Technologies was able to scan each trench line and mark out on the conduits and utilities with spray paint. Also, the analyst scanned with a utility wand capable of locating live electric and low voltage lines. By scanning the concrete prior to saw cutting, the contractor could safely cut the slab without the risk of damage. GPR uses no radiation making it safe for use in high traffic areas such as malls, hospitals and universities.
