If you're looking to add a bit more space to your home, you've probably already run into the term Build-Over Agreement. United Utilities are quite rightly protective of their sewers, and they'll want to know exactly where your drains sit before you start digging foundations. We've helped dozens of homeowners across Knowsley navigate this process. By using radio-frequency sondes, we can trace the exact route and depth of your pipes. We'll provide you with the invert levels and precise locations your architect needs for those CAD drawings, ensuring your plans get the green light without any nasty surprises mid-build.

There's nothing more frustrating than a contractor telling you they think a problem is somewhere under your lawn and then digging five different holes to find it. We hate seeing gardens in Kirkby get torn up unnecessarily. Our non-invasive mapping technology means we can pinpoint a collapsed pipe or a massive root intrusion to the nearest centimetre without lifting a single spade. It's a much cleaner, faster, and more affordable way to work. Why pay for hours of manual digging when we can find the issue in minutes using our sonar tracing gear?

From small domestic repairs to large-scale commercial site surveys across the Knowsley area, we provide the technical detail that professionals trust. We aren't just blokes with a camera; we're proud NADC members with WRC qualifications. This means our reports aren't just doodles on a page—they're accurate records that meet building regulations and local authority standards. If you're a developer or a homebuyer, having a professional drain map gives you the peace of mind that there are no hidden drainage disasters waiting to swallow your budget.
