▌Underground services surveys

Underground services surveys are carried out using Radiodetection C.A.T. & Genny equipment; (C.A.T: Cable Avoidance Tool).

Drainage runs can be traced by using a sonde transmitter on a reel; which is fed from the surface, along the pipe runs. The transmitted signal is traced from above ground using a detector. Cover & invert levels and pipe sizes can be provided. We are also able to trace other below ground services, e.g., cables, metal pipes etc., and can give depth information for the features detected, if required.

Measurements are carried out from the surface. Survey work is carried out in accordance with our company health & safety policy and safe system of working documents.

This equipment is usually sufficient to give a good indication of buried services, particularly when combined with utility companies’ records information, (that can be added to the survey drawings as a diagrammatic representation).

We are also able to meet the utility companies’ representatives on site to gain additional information, if required.

However, non-metallic services (e.g. plastic pipes etc.,), or underground void areas cannot be detected by this equipment. In certain cases, highly specialised equipment may be required. McLaughlin Ireland do not carry out CCTV / video underground pipe condition surveys. Also, we do not carry out electro-magnetic surveys or ground penetrating radar surveys. If you require these services, we are able to advise of specialist companies.
