How to Install a French Drain: pricing, tools, setting elevations. 4k video
What happens here
After the main trench is backfilled, the entire yard area is meticulously regraded. This step involves cutting down existing high spots and filling in low spots to create a gentle swale that directs all surface water towards the newly installed French drain. The goal is to make the French drain 'invisible' from the surface, but ensure that all surface runoff is effectively guided into its collection area. This process often involves multiple passes with heavy machinery to achieve the desired slope and evenness.
Goal: Establish a final grade that directs surface water efficiently to the French drain.
Tools and materials
- Grade Pole — Continuously checking final surface elevations
- Rake — Smoothing out the soil for a finished look
- Shovel — Addressing small areas or hard-to-reach spots during grading
- Tracked Skid Steer ASV RT-75 — Precision grading and moving soil to create the swale and final contours
