French Drain Planner

Plan the trench before digging. French Drain Planner turns run length, trench width, high and low depth, pipe, gravel, fabric, waste, and local prices into a material takeoff with pipe sections, couplers, gravel, fabric, fall, and rough cost. Use it to: - plan a trench in imperial or metric units - calculate pipe feet, pipe sections, couplers, gravel volume, and fabric length - include pipe overage, gravel cover, fabric overlap, waste, and local prices - review shallow or steep fall status and an optional phone angle note - save repeat drain routes on the device and share the current takeoff with its inputs This is a material-planning estimate, not drainage-performance certification. It does not locate utilities, approve outlet routing, provide permit or engineering guidance, or guarantee water removal. Confirm site conditions, utility locating, local requirements, product specifications, and safe digging practices before work. The core workflow works offline.
