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

What happens here

Excavate the main trench for the French drain system. The video shows mini-excavators being used to dig a deep trench along the property line and near the house. This specific 'hybrid' drain is dug deeper than a standard French drain to capture groundwater. Operators use a grade pole and level to maintain the correct elevation and pitch for effective water flow. The trench extends from the house area towards the storm sewer connection point.

Goal: Dig trenches to the specified depth and pitch to accommodate the hybrid French drain.

Tools and materials

  • Grade Pole — Measuring and ensuring correct elevation and pitch of the trench
  • Mini Excavator Bobcat 325 — Digging the main trenches for the French drain
  • Shovel — Fine-tuning the trench bottom and moving small amounts of dirt
  • Tracked Skid Steer ASV RT-75 — Moving excavated dirt and material around the wet job site
