What is a French drain? There is a lot of confusion out there about French drains, their benefits, and how they work. French drains are made of a small trench filled with aggregate that helps to move surface water away from the walls of a property. Lots of people use them in their driveways or gardens when they know the areas are prone to flooding. Sometimes surface water doesn’t drain away correctly due to the lay of the land and many other factors. A French drain should ensure that never becomes a problem because it channels all the liquid away from the building. In most instances, people fill French drains with stones or other materials so they can’t see the flow of water. www.bdsdrainage.co.uk
How Does a French Drain Work? As mentioned a moment ago, French drains ensure any rainwater in outside your property will flow away from the building. The liquid runs into a gravel trench and then flows into a pipe at the bottom of the drain. The water travels through the tube and then empties somewhere safe away from the house. It’s vital that anyone who creates a French drain in their gardens makes sure the ditch slopes one inch every couple of feet. That should be enough to ensure the water moves in the right direction and never creates a flooding issue on the property. In many instances, people who build French drains will send the surface water to a low-lying part of the property, a drainage ditch, or straight into the street. Call: 02036 757 174
