Client project involved significant ground modifications and piling work. Requirement therefore to obtain accurate position and depth measurements of underground features that cannot be located by signal connection or induction.

NB Solution

NB Surveys uses state of the art ground penetrating radar equipment (GPR)


The GPR detects anomalies in the sub-surface structure, and although commonly used for underground pipe and utility detection, it is also an aid to the location of foundations, voids, and archaeological features. It provides easy to interpret results, which simultaneously indicate the position and depth of metallic and non-metallic targets. By systematically covering the area in question with a series of scans, the linear route of any utility becomes clear.


  • Eliminate risk of damaging utilities during excavation
  • Safer site work
  • Design foundations and piling operations with confidence
  • Reduced contingency requirement
  • Reduced Costs
