Question: What are French drains? When are French drains useful?
If your neighbor’s land stands at a higher elevation than yours, you may be experiencing problems with excessive moisture on your property. Water from your neighbor’s property may be running down the slope and spilling onto your property. You need better yard drainage. One option in such cases is installing French drains.
When some people speak of a “French drain,” they refer to a trench in which a drain pipe is laid, but the traditional French drain is basically a trench filled with gravel.
