A very firm subsoil or depressions in the ground prevent rainwater from draining away. Puddles form on the lawn that drains slowly. It doesn’t get the lawn roots at all. In most cases, the problem can be solved with drainage.
Water cannot drain
The cause of a wet lawn is that the rainwater cannot run off because the soil is too compacted.
Even in uneven gardens, there are puddles on the lawn because the water collects in the depressions and seeps into the ground there only slowly.
Before planting a lawn, you should level the area and fill in any depressions. On slopes, make sure that the rainwater flows outdoors or is collected in a septic tank.
Lay the drainage yourself
Laying drainage yourself to drain the lawn is not as easy as most home gardeners think. Get advice from an experienced garden technician or hire a company that does the drainage professionally.
It is important that the pipes are laid with a gradient of around three percent so that the water can drain off and the lawn can dry. Otherwise, it can back up and lead to further flooding.
Depending on the scope, you will need a small excavator for the earthworks and the introduction of gravel, fleece, and pipes.
You need this for drainage
- drainage pipes
- purge pipes
- If necessary, a small excavator
- septic tank
The drainage pipes have slits at the top through which the water enters the pipes. To prevent the pipes from clogging, they are placed in a bed of gravel at least 15 cm (5.8 inches) thick and covered with fleece.
They should be buried at least 50 to 60 cm (19-23 inches) deep and covered with soil
Mark the route of the pipes so you don’t accidentally damage them later when digging.
When draining the lawn, do not direct the water onto the street or even into the city sewer. In most communities, this is not allowed. To be on the safe side, find out beforehand what conditions you have to comply with when installing a drainage system.
