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

What they say

Hide

backyard and this is where we wanted to make sure that we were getting our elevations set for that French drain but our outlet to this French drain is 200 feet away and so this French drain is set at the right elevation at about 12 inches below grade but as we come closer to that Street that's where you see that we had to deepen it to make sure that everything was still flowing downhill I know I've said it I just want to make sure that we're in graining how important it is to make sure that you don't have any unevenness in that elevation change [Music] so once we've got our French drain installed now we've got to make sure that we get the grades to flow into it and that remove means removing the excess soil that's on the yard and creating a gentle swale down to the French drain we don't actually want a trench going to the French drain we want the French drain to be invisible but we do want to direct and guide all the water down into that area and so that means we're going to end up regretting this backyard cutting down all of the grades to make sure that we have all of their elevation set not just in the drain itself but the surface elevations set as well so everything flows to where our drain tile is buried because if it doesn't then we're going to get pooling spots in different locations all right we're back
