Sonde Drain Tracing Services

Need to find the exact route of a drain underground? We provide professional sonde drain tracing to locate pipe runs, identify direction of flow, and help pinpoint blockages, defects and inspection chambers without unnecessary digging.

What Is Sonde Drain Tracing?

Sonde tracing is a method used to locate drains underground by pushing a specialist sonde or camera through the pipe and tracing its position from above ground using locating equipment.

This allows us to map out the approximate route of the drain, locate hidden chambers, and identify where problems may be sitting below the surface.

When Drain Tracing Helps

  • Locating hidden or buried drainage runs
  • Finding inspection chambers
  • Identifying direction of flow
  • Pinpointing blockages or defects
  • Planning excavations and repairs
  • Pre-purchase investigations
  • Confirming drain layouts before building work

Why Drain Tracing Is Useful

Not all drains run where you expect them to. On many properties, especially older homes and altered buildings, underground drainage can take unusual routes or disappear below extensions, driveways, patios or landscaped areas.

Sonde tracing helps us understand where the line runs so repairs, surveys or excavations can be carried out more accurately and with less disruption.

It can also save time and money by reducing guesswork and helping identify the most suitable place to investigate further.

How We Carry It Out

  • Access the drainage system via a chamber, gully or SVP where suitable
  • Insert tracing equipment or CCTV sonde into the pipe
  • Track the signal from above ground
  • Mark the approximate route of the drain
  • Identify possible chamber locations, defects or problem areas

Pricing

Drain tracing visit: From £150

Pricing depends on access, site conditions, and whether tracing is being carried out alongside unblocking or CCTV survey work.

If tracing is required as part of a larger investigation, we can advise on the most cost-effective option when booking.

Can Drain Tracing Be Combined With CCTV?

Yes. In many cases, sonde tracing is most useful when combined with a CCTV inspection. This allows us to see the condition of the drain internally while also identifying where the camera head or sonde is sitting underground.

This is especially useful when trying to locate cracked sections, root ingress, collapses, hidden chambers or the best area for excavation.
