How can I effectively use gravel around my house for drainage purposes?

To effectively use gravel for drainage around your house, first dig a trench along the area you want to drain. Fill the trench with a layer of gravel, ensuring it is level and compacted. Place a perforated pipe on top of the gravel to help water flow away from the area. Cover the pipe with more gravel and top it off with a layer of soil or mulch. This setup will allow water to drain efficiently and prevent flooding around your house.
