French drains, despite their title, were originated in America and essentially work by offering invasive groundwater using a path of least resistance by way of which it can be diverted away from construction or low-lying part of the yard.
These days, French drains are usually utilized to combat flooding problems brought on by surface and/or groundwater a homeowner may be having, particularly affecting their yard, basement or foundation.
The simple layout, a gravel-filled trench, is easy but for it to keep on working through the long haul, it is important that it be well implemented.
Flooding problems are generally related to sloping ground, non-porous clayey soil, or a combination of both. By way of instance, if your house is built on a slope with your neighbors’ house occupying a great deal higher up the slope, heavy rain can precipitate an accumulation of groundwater rushing from their property and on your own.
If your soil is unable to absorb all of that water, you might well experience damage to your home’s foundation, or leakage into a crawlspace or basement under the ground floor of the home.
A linear French drain is an easy, cost-effective remedy to such an issue. In this scenario, it serves as a moat that protects your property by intercepting the groundwater hurrying down the slope and directing it around and away from the house’s foundation. So, let us get down to the nitty-gritty both of how to construct a French drain, and how it works.
