The detection of gas was very quick and obviously the leak was close by. We were given a spot to dig but even after opening quite a long trench we found no pipe or substantial water ingress into the trench. I have returned today and opened a longer trench at right angles and now found the leak. The leak was actually 2.1 meteres from the indicated spot. Without LDS we would not have had a hope in hell so glad we used the service. The area above the leak is gravel but unbeknown to me the gravel sits on 3 inches or so of rough concrete so I think the gas was running under the concrete and then under some slaps before exiting from the weakest point where the slabs butt the house wall.
