Drainage is buried forever after backfilling. Capture GPS-tagged evidence of runs, chambers, and connections while they're still visible.
Photograph drainage runs, bedding materials, and fall gradients before backfilling. GPS coordinates prove which run belongs to which plot.
Document inspection chamber construction, benching, cover levels, and connections with geotagged photos linked to the correct plot.
Drainage positions are buried and invisible after backfilling. GPS coordinates on every photo provide permanent location verification for your NHBC inspector.
Drainage works happen in open ground, often before site infrastructure is complete. ProPlot works without signal — capture everything offline.
Generate drainage evidence reports for any plot — all photos, GPS data, and annotations ready for NHBC or building control in one tap.
See which plots have complete drainage evidence and which are awaiting documentation. Never miss a drainage inspection.
Drainage is a key NHBC inspection stage because it's permanently buried after backfilling. If defects surface after completion — collapsed runs, incorrect falls, or failed connections — the only evidence of original installation is your photographic record. GPS-tagged photos prove what was installed and where.
Key items include pipe runs showing fall direction, bedding and surround materials, inspection chamber construction and benching, connection points to mains, soakaway construction, and gully positions. ProPlot helps you track which items have been captured for each plot.
Yes. ProPlot's audit system lets you attach notes and reference numbers to geotagged photos. You can reference CCTV survey reports alongside your photographic evidence for a complete drainage documentation package.
GPS coordinates are captured at ground level when you photograph the open trench — before backfilling. The coordinates mark the surface position of the drainage run, providing sufficient accuracy for inspection and warranty purposes.
