A French drain (also known by other names including trench drain, blind drain, rubble drain, and rock drain) is a trench filled with gravel or rock, or both, with or without a perforated pipe that redirects surface water and groundwater away from an area. The perforated pipe is called a weeping tile (also called a drain tile or perimeter tile).
