Ground Penetrating Radar
WSL use the market leading IDS Detector Duo (dual frequency 250 MHz & 700 MHz) Ground Penetrating Radar (GPR), to locate buried non- metallic and metallic objects, pipes and cables.
GPR is one of the most advanced underground service locating techniques when combined with electromagnetic locating.
It is used for the location and survey of conductive and non-conductive subsurface services and structures. It is the ideal way to locate:
The GPR technology uses electromagnetic (EM) waves transmitted from an antenna (Tx) which reflects on layers and objects in the ground. These reflections are received with an antenna (Rx) and create a picture of the subsurface. As the transmitting and receiving antenna is moved along the surface, recordings are collected and displayed side by side. The result looks like a cross section also known as radar profile.
GPR can be used in a variety of media including rock, soil, ice, fresh water, concrete, pavements and structures and it can detect objects, voids, cracks and changes in the material.
