What is the French Drain Used For?
Not only is this type of drain aesthetically much more attractive than a typical drainage system but its main benefit is specifically to usher water away from your home. It's capable preventing terrible erosion issues and practically any other cause of rising damp problems from occurring through the exterior of your home's walls. The French Drain has been around for decades and was originally invented in the 1850s. Needless to say, a system this attractive hasn't had any trouble sticking around for this long.
Perhaps the most obvious benefits is that like any drain, the French drain works to remove water and get moisture away from your home or building. However, this type of drain is designed specifically to work on structures that are built at the bottom or on the sides of hills. This can become extremely valuable when it comes to creating a place to keep your home dry and your foundation safe, especially in a wet country like England!
Do I Have Any Options
Sure you do! Unlike typical drainage that causes you to collect rain in a few specific areas around your yard or house, a French drain can be set up so it transfers water from an area you don’t want moisture to an area that needs more moisture. If for example you would like to transport water from your home down to your garden, you could very easily and economically do this with a French drain set up.
Worried About Efficiency?
These types of drains were created using the main principles of physics so if you decide that you would like to surround your entire property with them, they'll still work perfectly, and as such, they become much more economically feasible and cost efficient when compared to other drainage systems.
For people with complicated irrigation problems, or who might be working with a tight budget, French drains are phenomenal when it comes to choosing and creating the best and most attractive options for drainage within a tight financial outlook.
The biggest benefit of this type of drain is that the installation that takes place with the materials is lightning fast. It won’t take months or even weeks to install and you won’t need to uproot your entire house or backyard to add them in. If you need an effective drainage system quickly, they work wonders when it comes to getting the job done and keeping your house and foundation dry in just a matter of a days' time.
If you do live at or near the bottom of a hill, or even around an elevation change of any kind, chances are that you are having some kind of water accumulate in parts of your home that you shouldn’t have. By adding French Drains you’ll find out how much piece of mind you’ve restored, and how much money you are able to save. Simply re-channeling water and avoid run off right into your home or other building can make a world of difference. By adding this drainage system before you know it, water breaking down your walls will be the last thing on your mind.
The Tech Specs
A French drain is also known as weeping tile or a blind drain. Essentially, it is a trench filled with gravel or rock that contains a perforated pipe that redirects surface water and groundwater away from a particular area. A French drain is designed to have perforated hollow pipes along the bottom to quickly vent water that trickles down through the upper gravel. The most common features of these systems include lightweight gravel, such as pea-shingle, as a substitute that is wrapped around perforated corrugated pipe.
French drains are mainly used to prevent ground and surface water from damaging your homes foundation. French drains are also often placed behind retaining walls to relieve ground water pressure from building up.
French drains are often installed around the foundation of
your home foundation in a few different ways:
- They are buried around the foundation wall on the external side of the foundation, and
- They are installed underneath the basement floor on the inside perimeter of your basement.
In most homes, an external French drain is installed around the foundation walls before the foundation soil is backfilled. It is then laid on the bottom of the excavated area, and a layer of stone is laid on top. In some cases, a filter fabric is then laid on top of the stone to keep the more fine sediments and particles from penetrating. Once the drain has been installed, the area is then backfilled as well. The system is then left alone unless any type of clogging occurs.
Most commonly, this is done in response to basement that's become soaked or right before performing a basement finishing. To install a French Drain, the perimeter of the basement floor is jack hammered down to the footing and then the concrete is removed
after. A layer of stone is then placed, and a perforated drain pipe is laid on top of it. Water is then allowed to be collected from the basement's walls, floors, and joints into the system. A pump must also be installed in order to remove water from the house and away from the foundation.
