FRENCH DRAIN PROJECT PLANNER
From trench geometry to a drain material order.
Subtract the pipe from the gravel volume, round pipe to purchasable stock lengths, estimate couplers and full-wrap fabric, see total slope drop, check gravel on hand, work backward from a budget, or compare gravel suppliers.

WHY THIS PLANNER IS DIFFERENT
Pipe stock and fabric are purchase quantities too.
French-drain calculators often stop at gravel volume. This planner also handles exact pipe displacement, whole pipe sections, couplers, full-wrap fabric, slope drop, budget length and gravel supplier quotes.
Plan the full material orderEstimate gravel, tons, bags, pipe stock, couplers, fabric and entered slope drop.Use gravel you already haveConvert tons, yards or bags into the maximum drain run your material can support.Plan from a budgetSearch whole-foot lengths using discrete pipe sections plus gravel and fabric costs.Compare gravel suppliersNormalize per-ton and per-yard quotes to the exact entered trench requirement.
