A French drain is a drainage system designed to redirect excess water away from a building or an area prone to water accumulation.
It typically consists of a trench filled with gravel or rock and a perforated pipe laid underground.
When water enters the trench, it flows into the pipe and is carried away from the problem area, preventing water damage, flooding, and soil erosion.
French drains are commonly used in landscaping, foundation protection, and waterproofing to manage water runoff effectively and keep areas dry and stable.
