Our Tracing Service

Using specialist Sonde equipment, we are able to carry out our drainage and ducting inspections and surveys with the utmost precision. This addition to a camera survey allows us to find the precise depths of drains up to 9 meters underground, and facilitates the accurate tracing of drains and ducting. This allows us to mark their exact locations on the surface and is especially helpful when planning construction works. The Sonde equipment enables us to mark precisely in the drain where the problems are, this helps with the efficiency of any repair work we may carry out.

Fixed Price Drain Tracing

Often, drain surveys are required to diagnose problems within the drains, or as a means to ascertain where drainage runs lay on a property. The Sonde service enhances the accuracy of CCTV camera surveys, and this is why these are quoted on an individual basis. We can provide a range of different styles and types of plan to suit your requirements. If you need detailed engineering drawings or an illustrative diagram of depth, we can provide exactly what you require. Prices for our Sonde service start from £150. You can contact us via telephone, email, online chat or submit a request us to call you back.


Our Range Of Techniques

The Sonde is a specialist piece of equipment that transmits high frequencies, facilitating the accurate tracing of drains, sewers, and ducting. The Sonde accurately pinpoints where damage in the drains is in relation to the surface. As an attachment to our CCTV camera equipment, it is the perfect addition to a CCTV inspection if more precise details are required, such as the depths of particular drains, where they correspond to on the surface, or where digging is required for drain repair work.
