Drain Mapping Locating in Godmanchester, Cambridgeshire

The old way of finding a pipe involved digging 'trial holes' and crossing your fingers. We think that is a bit primitive, not to mention messy. Instead, we use what is known as Sonde and Trace technology. We'll pop a small transmitter (the sonde) into your pipework, which sends a signal back to a receiver on the surface. This allows us to trace the exact route and depth of your drains through concrete, soil, and even deep foundations. It is entirely non-invasive, meaning your patio or driveway stays exactly as it is while we work. We can even identify invert levels and directions of flow, giving your architect or builder everything they need to draft up those plans with total confidence.

If you are building within three metres of a public sewer in the Cambridgeshire area, you'll likely need a Build-Over Agreement from Anglian Water. They are quite strict about this, and for good reason—nobody wants a collapsed sewer under their new kitchen. To get that legal green light, you will often need a professional drainage survey and a schematic drawing showing where the pipes are located. Our team specialises in providing the high-definition CCTV drain surveys and sewer mapping required for these applications. We will map out the connections and provide the technical data needed to satisfy the water authority and local building control, making the whole planning process a lot smoother for you.

Have you ever wondered where a particular gully leads, or why a certain patch of ground stays damp? Sometimes, a standard camera survey is not enough to solve the mystery. That is when we break out the specialist tools like dye testing and sonar tracing. By using non-toxic, brightly coloured dyes, we can track exactly where water is flowing and identify hidden cross-connections in your system. It is a simple but brilliant way to map out complex networks in older Godmanchester properties. When combined with our underground pipe tracing, you get a complete picture of your drainage infrastructure, identifying everything from hidden manholes to abandoned Victorian pipes that aren't on any official records.
