what is a french drain system？
A French drain is a trench filled with a perforated pipe and gravel that allows water to drain naturally from your yard. Depending on the size of your yard and the scale of your drainage issue, you can purchase the pipes and equipment to create a French drain yourself.
Similarly,What is the difference between a French drain and a regular drain?
You'll find that the primary difference between the two systems is that French drains deal with water that gradually seeps below the ground, while surface drains redirect water that's accumulating above ground. Always consider the purpose of the drain because making the best choice is important.
Furthermore,Why would someone install a French drain?
If you are facing recurrent drainage issues on your property, you may need a French drain to effectively remove that excess water and get it away from your foundation. Avoiding damage to your property, particularly your foundation and basement, is the main purpose of a French drain.
Subsequently,When should you use a French drain?
French Drains are primarily used to drain groundwater from gardens and around the foundations of buildings. French drains are designed to move water that is trapped in the ground away or towards an area. They are best used in soil that is prone to frequent saturation from rain or flooding.
Furthermore,What is a French drain and how does it work?
French drains provide an easy channel for water to flow through. Water runs into a gravel-filled trench, then into perforated pipe at the bottom of the trench. Water travels freely through the pipe, which empties a safe distance from the house.
Over time, a French drain may become clogged. Tiny soil and clay granules slip through the pores of the landscape fabric and gradually build up inside the pipe. Another common cause of French drain clogs is root intrusion from grass, shrubs, and trees.
The main difference between the two is that French drains capture and remove groundwater while trench drains quickly remove surface water before it can saturate the ground. Here's a closer look at each type of drain.
A properly designed French drain system does not require an outlet. The water will simply soak into the soil as it flows along the perforated pipe. In fact, a French drain doesn't require an inlet on just one end either.
Officially a French drain is a gravel drain with no pipe. The water just collects in and travels through in a gravel or stone filled channel that starts from the surface or just below it.
According to Fixr, the average French drain costs $4,500. An exterior drain located fairly close to the surface could cost as little as $1,000, or $25 per linear foot on average. Drains installed under your basement floor could cost $2,000 or more. Expect to pay $60 to $70 per linear foot for installation.
The two ends of a French drain system are: The drain field, or high end, where excess ground water enters the drain pipes. The drain exit, or lowest point, where water leaves the system.
How Close Should a French Drain be to the House? A good rule of thumb is to install french drains 3 feet from the house. Make sure to measure around the porch, patio and deck.
When enough sand, clay or silt gets past the fabric, the gravel spaces fill and the effectiveness of the french drain ends. This is why most experts state that a French drain is not a long-term solution to a drainage problem: You have to dig it up and reinstall it every eight to 10 years.
