Utility Tracing

Utilities Tracing


Underground utility tracing and mapping is carried out as a means of producing detailed underground services drawings. Geophysical techniques including electromagnetic detection & ground penetrating radar are used to prove the position and depth of services. Collaboration with our topographic surveyors is common place during utility surveys as a means of combining topo & tracing data to produce drawings.


Specialist ferroscan & concrete imaging surveys are also carried out to detail rebar type, size & spacing within concrete structures. These are primarily undertaken to identify suitable drilling locations and verify the structural integrity of concrete formations. Voids and other anomalies can also be detected using GPR to further assist in the investigation of existing structures.


Other specialist geophysics surveys can be carried out for purposes such as geological investigations, environmental hazard detection, structural assessments & brownfield / landfill site characterizations.
