Drain Mapping
Our drain mapping process uses a combination of dye testing, sonde tracing, CCTV verification, and GPS plotting to trace underground drainage networks, pipe connections, and flow direction. This method is ideal for sites with limited documentation or complex drainage systems.
We provide clear, GPS-referenced maps, CAD and PDF layouts, and asset schedules that detail invert levels, pipe sizes, and connectivity notes. Whether you're validating data, planning excavation, or preparing adoption submissions, we ensure you know exactly what's underground.
