Ground Penetrating Radar Survey (GPR)

Ground Penetrating Radar Survey (GPRS) provides a safe and non-invasive method of conducting speculative searches with the need for unnecessary disruption and excavation.

Principle
Radar survey work by launching pulses of energy into the soil or ground. These pulses are reflected by any subsurface objects that may present. It detects non-metallic utilities such as PVC Water and Gas pipes. Asbestos pipework and Fibre-optic cables. These utilities are not normally detectable by using other survey methods.

Our Ground Penetrating Radar Equipment
