Many homes, businesses, and industrial buildings use a french drain as the main component of their drainage system, as it has proven to be a highly-effective system. What exactly is a French drain and how does it work? We’re glad you asked! Follow along and get some answers to learn more about how a French drain can keep your home dry and safe.
The Basics of French Drains
The structure that makes up a French drain is designed to make water flow through it smoothly and effectively. The water flows eventually to a trench which is filled with gravel, and finally through a perforated pipe at the bottom. The most important part of the system is the point at which the pipe empties, which must be a calculated distance from the home to ensure the home will not be at risk of water damage.
Trench Bottom Design
The bottom of the trench drain must be designed and placed very specifically. The bottom should be sloped approximately an inch for every 8 feet in the direction in which the water should flow. This point cannot be stressed enough; it will make or break the entire system.
Deciding where to divert the water can be a difficult decision depending on the layout of your property and will certainly require a professional opinion. The best places to divert your water are typically the street, a drainage ditch, or a low-lying area of your yard/property.
Do I Need A French Drain?
If you have any moisture problems in your home, it is best to get all water as far away from your home as possible. Many families will notice telling signs such as a frequently wet lawn or water exposure in your basement. If you experience any of these issues, you should inquire about getting a French drain.
