<p>Planning an extension often brings up the dreaded 'Build-Over Agreement'. If you're in the Sefton area and your new walls are going anywhere near a public sewer, United Utilities will want to see exactly what’s down there. We provide CAD-ready reports and GPS mapping that architects and water authorities love. We'll find the 'invert level'—that’s just a technical way of saying the pipe's depth—to make sure your foundations don't cause a collapse later on. Why risk a massive bill when you can get a clear underground blueprint first?</p>

<p>Remember the days when finding a pipe meant digging a series of holes until you hit something? Those days are gone. We use a battery-powered transmitter called a 'sonde' that travels through your pipes while we track the signal from the surface. Combined with our high-definition CCTV survey, we can spot a root mass or a crack and tell you exactly where it is to the centimetre. It’s a non-invasive underground location method that keeps your Formby home’s garden or driveway perfectly intact while we do the detective work.</p>

<p>If you're buying a new home in Formby or Litherland, the last thing you want is a hidden drainage disaster. Our site surveys are a bit like an X-ray for the property. We've helped plenty of people avoid buying houses with collapsed lateral drains that would have cost thousands to fix. For commercial developers in the Sefton area, we map out complex drainage systems to ensure your site plans are 100% accurate from day one. As a drainage expert with NADC membership and WRC qualifications, we provide advice you can actually trust.</p>
