Underground Utility Detection and Mapping Surveys

Underground Utility Detection

Underground services and their locations can be a critical factor in any development – the cost and time scale factors in re-routing services or having non-existent services supplied can be the deciding factor on the viability of a scheme. We have many years of experience and some of the best modern equipment to map these services without having to excavate.

Radio Detection

By using the latest Radio Detection (CAT type) equipment along with signal generators and plans supplied by the utility companies we can locate metal objects to provide details of the service locations and, if required, an estimate of depth.

  • Can only trace metallic services unless a trace wire has been buried with non-metallic services.
  • Difficult to distinguish between services unless a positive trace signal can be applied at a stop valve or similar and even then signal can be transferred into adjacent pipes or cables.
  • Difficult to resolve signals within 1m of buildings, walls, parked cars etc.

Ground Penetrating Radar (GPR)

If pipes are made of non-metallic materials such as plastic or asbestos cement we use Ground Penetrating Radar which indicates the presence of services and voids by timing the radar signal reflected from the ground

  • Depth penetration limited to 3m and resolution is poor below 1.5m.
  • Resolution in made up ground, waterlogged ground or that which has been previously disturbed may be poor.
  • Unable to distinguish between services other than by size.
  • Unable to be used on very rough ground, in dense vegetation or close to obstructions.
