French drains are needed in situations where a yard is constantly soaked, or when there is a wet basement. Where there is water, it will take the easiest way to flow downhill, which is where a French drain comes in. A French drain consists of a trench that is slightly sloped, and is filled with round gravel. Inside the trench is a pipe, which serves to divert water away from the home or area of concern.

A trench is filled with gravel, allowing the water to run freely through it, and into a perforated pipe located at the end of the trench. The water is then emptied at a distance that is deemed to be safe, preventing the buildup that leads to saturation and flooding.
