A French drain, also known as an interior drain or weeping tile, is designed to redirect excess water away from your home’s foundation. From the video, ‘HOW A FRENCH DRAIN WORKS,’ you will find clear, easy-to-understand explanations of how this drainage system functions and the most common types used today.
French drains are trenches filled with gravel and sometimes perforated pipe. Water that would otherwise become trapped around or near a home’s foundation, causing damage from moisture and pooling, is diverted into the trench through a series of pipes. These drain tiles usually end at a discharge point.
Typically, an uphill area where gravity can help move the water away from your home.
That may be through a sewer system or an infiltration basin, where the water can soak into the ground and make its way back to groundwater. When it rains, the excess water has no choice but to make its way toward your home’s foundation. If there is nothing in place to move the water away, it will pool around your foundation and cause damage.
French drain companies help redirect this excess water away from your home and toward the discharge area. French drains can be installed to manage surface runoff or under-slab waterproofing, as long as the gravel is covered with a filter fabric and perforated pipe is used in an arrangement that allows it to drain from the wetter area to a dry one. French drains can also help you avoid handling problems by preventing structural damage from excess water and pooling.
