SafeGround’s radiosonde survey traces non-metallic pipes, drains, sewers, culverts and conduits.

The radiosonde device is a self-contained transmitter that can be propelled along the length of pipes.

Our operators on the surface follow the movement of the radiosonde using a RD8000 receiver. If required, optional ground penetrating radar can provide a more accurate indication of depth.

The location of the pipe can be traced, marked out on site using paint and mapped onto a CAD plan. The maximum depth that can be determined is up to 10m, subject to ground conditions. Lengths up to 200m can be examined.

If the purpose of the procedure is to find a collapse, the movement of the radiosonde will stop at the point of blockage and radiate a signal.
