Drain Mapping Locating in Cambridge, Cambridgeshire

We don't just guess where pipes might be based on where your sinks are. We use something called 'Sonde and Trace' technology to get a pinpoint accurate reading. Essentially, we send a small transmitter (the sonde) through your pipes, and our engineers use a receiver on the surface to track its exact path and depth. It works through concrete, deep soil, and even under thick floorboards. This means we can map out your entire network without moving a single spadeful of dirt. It is clean, fast, and gives your architect the exact invert levels they need to keep your project moving forward.

Are you planning to build within three metres of a public sewer? In the Cambridgeshire area, you'll likely need a Build-Over Agreement from Anglian Water before you can even lay the first brick. They won't just take your word for where the pipes are; they require professional evidence. We provide the high-definition CCTV surveys and schematic drawings that prove your new foundations won't crush a vital pipe. By getting your drain mapping done early, you avoid those stressful delays where a building inspector halts work because of an unexpected lateral drain or a hidden junction.

It is surprising how many inspection chambers get buried under layers of tarmac or fancy new patios over the years. If you suddenly have a blockage and your manhole is hidden, you're in for a rough time. We use our locating gear to find these 'lost' access points quickly. Whether it is for a quick repair or a full-scale commercial utility survey, knowing where your access points are saves hours of searching. It also prevents you from having to rip up your beautiful landscaping just to find a lid. We've helped dozens of neighbours across Cambridge find hidden infrastructure they didn't even know existed.

As a local team based in the area, we have worked on everything from narrow city-centre terraces to sprawling new developments in Ely and Soham. We aren't just 'blokes with a van'; we are Construction Line Silver accredited and hold £10 million in public liability insurance. We take the technical side of drainage seriously so you don't have to worry about the 'what ifs'. Whether it is a simple dye test to see where a pipe connects or a complex site map for a developer, Roberts Drainage Ltd provides a clear, honest picture of your underground assets.
