Recently, I had trouble with my land constantly becoming waterlogged and as a result very swampy. I couldn’t even step on it without it getting worse.
I did some research and found that a french drain would be the perfect solution. However, my next immediate question was:
What exactly is a french drain?
A french drain is basically a pipe that lays in a sloped trench, filled with gravel or aggregate. The basic premise is that water always flows downhill and and therefore, the pipe will lead water away from your land.
I found out all this information from a great article on Valley Rise Landscapes website. They are a respected landscaping company in Preston and created a quality guide all about land drains.
You can read the article here: The definite guide to land drainage systems.
How do french drains works?
French drains essentially just provide an easy route for water to flow along. The water will run down a slope, flow through gravel or aggregate and then through the small holes in the perforated pipe, at the bottom of the trench.
The water continues to flow until it reaches a collection point which will ideally be a fair distance away from your garden.
Good collection points to get rid of your excess water could be a drainage ditch, a dry well or the street.
When you need a french drain?
If you have a problem with surface water, such as a waterlogged garden or piece of land, you could definitely benefit from having a french drain installed.
If you’re building a retaining wall on a hillside
If you’re building a retaining wall, make sure to add a french drain behind the blocks or stones.
If you fail to do this, water flowing down the hill will eventually start to build up against the wall.
If you need help with building a retaining wall or installing a french drain or land drainage system. Check out Valley Rise Landscapes, after reading a couple of their articles and viewing their work, I advise you to give them a try if you live around Lancashire.
