If you're dreaming of a bigger kitchen or a sunroom, the first thing your architect or the folks at United Utilities will ask for is a drain map. You can't just build over a sewer without a formal 'Build-Over Agreement,' and they won't sign that off if you're just guessing where the pipes are. We've seen projects in Sefton grind to a halt because a builder hit a lateral drain that wasn't on the old plans. We provide the CAD-ready drawings and accurate invert levels (that’s just the depth of the pipe) that keep the planners happy and your project on track. It's about getting it right the first time so you aren't dealing with a collapsed drain underneath your brand-new floorboards a year from now.

You might be imagining us turning up with shovels and making a mess, but it's actually much more high-tech than that. We use something called a 'Sonde'—a tiny, battery-powered transmitter that we pop into the drain. As it travels through the pipe, we use a handheld receiver on the surface to pick up the radio signal. It's incredibly accurate; we can pinpoint the location to within a few centimetres. By pairing this with our CCTV drain surveys, we don't just find the pipe; we see exactly what state it's in. If there’s a root mass or a crack, we’ll find the 'X' that marks the spot, meaning if we ever do have to dig, we only dig once, in the exact right place.

For our commercial clients and developers across Sefton, having an underground blueprint is vital for health and safety and asset management. If you're managing a large site, the last thing you want is a contractor hitting a main sewer line because it wasn't on the map. Our team provides comprehensive site surveys, including GPS mapping and detailed condition reports. We're fully NADC certified and WRC qualified, so you know the data we hand over is up to industry standards. From simple pipe tracing to complex sonar mapping of an entire network, we've got the tools and the local knowledge to get the job done quickly and professionally.
