Start with what you have noticed
A buried leak can discharge into the ground with very little surface evidence. Where water does appear, it may have travelled away from the damaged pipe. A planned investigation helps avoid opening a driveway or garden in the wrong place.
Build a picture of the buried route
The engineer assesses accessible connection points, possible pipe routes and the behaviour of the supply. Listening or tracer testing may help narrow the search, depending on pipe material, depth and surrounding conditions. We compare the results before proposing an access area and explaining the excavation needed for repair.
Signs that can prompt an investigation
- Wet soil that does not dry out
- Supply water disappearing below paving
- A suspected pipe leak beneath concrete
- Unexplained consumption on an outside supply
Planning the visit
Mention gates, parking, private lanes and any known buried services. Existing drawings can help. Leave the surface intact until the investigation supports a reason to open it.
What to be aware of
A method that may help
Tracer gas detection
Trace escaping gas from suitably prepared water pipework when other clues are limited. The engineer selects the appropriate combination for the property.
