Sonde Tracing

Home / Services / Drainage / Sonde Tracing

Chelmer are able to map your underground drainage runs using a SONDE transmitter. This device is able to detect all non-metallic drainage runs and ducts.

The SONDE can be attached to our CCTV camera equipment and we are therefore able to trace pipes and locate with accuracy the exact position of any defective sections.

If a fault such as a collapse or blockage is encountered, we are able to accurately record the depth and location of each fault, allowing accurate pricing and efficient repairs.

Sonde tracing is often an invaluable tool for ‘blind’ drainage systems where there is no apparent access into the system, i.e. via a manhole.

Often, rainwater systems are ‘blind’ and Chelmer are able to map/investigate the layout of such systems using our Sonde tracing techniques in conjunction with a CCTV camera.
