How to Install a French Drain: pricing, tools, setting elevations. 4k video

What happens here

Line the excavated trench with permeable filter fabric. This fabric allows water to pass through but prevents fine soil particles from entering and clogging the drain tile. Next, lay the corrugated, perforated drain tile into the fabric-lined trench. The video emphasizes using perforated drain tile that is flexible enough to handle angles and changes in grade. Once the drain tile is in place, cover it with a layer of washed rock (clean aggregate). The more rock and fabric used, the more effective and longer-lasting the system will be.

Goal: Construct the core drainage system within the trench.

Tools and materials

  • Corrugated Perforated Drain Tile — Collecting and channeling water within the trench
  • Grade Pole — Verifying elevations while laying components
  • Permeable Filter Fabric — Lining the trench to prevent soil fines from clogging the drain tile
  • Shovel — Distributing rock and managing fabric
  • Washed Rock — Encasing the drain tile to create the drainage zone

where a big portion of the problem on this jobsite came from which was subsurface water we wanted to be more aggressive with capturing that subsurface water and getting it to go down into the storm sewer drain so this system is going to be deeper than your standard French drain just at the outlet now the rest of our real French drain is almost 200 feet away so we had to account for that elevation pitch when we were setting our French drain field and I want to reinforce that so that if you guys are out there looking and doing your own French drain system you don't follow this video exactly you want to go about 12 inches deep with your French drain now another question that's come up is how much do a charge for a French drain on a project like this will typically get anywhere from $25 per linear foot up to around $40 per linear foot and that does not include regrading the yard re-sodding or anything else what that does include it includes the drain tile filter fabric rock hauling away the excavation spoils which is part of the project and then putting everything back in place including the labor to do that but any other landscaping that happens to be a part of this project would be charged separately hope that helps
