Good morning,
Our driveway is approximately 10 x 5 meters (33 x 16 feet) in size. According to the development plan, we have to use permeable paving, such as drainage or eco-pavers.
We were advised to slightly slope the entire surface and to install a channel drain at one corner.
Is something like this really necessary with drainage paving? I have never consciously seen this and can't quite imagine it.
Best regards,
Katrin

Vicky Pedia20 Jan 2020 13:18I can only agree with the others. I also have a parking space with permeable paving and an additional channel. But even during heavy rain, all the water drains away. The channel is there now and provides some reassurance, but it wasn’t actually necessary.

hampshire20 Jan 2020 13:31You will need a procedure like this at the latest when an inspector comes and requests it—I have experience with this.
For our previous house, we paved the section leading to the street in such a way that a kind of wider channel was created, sloping toward a planting bed. That was enough for the city’s water management officials.
The neighbor’s 6 x 6 m (20 x 20 ft) paved parking space without drainage was not objected to.
One house over, a drainage channel had to be retrofitted for a 1 x 3 m (3 x 10 ft) area, and the connection to the soakaway had to be demonstrated.
The rule was clear, but enforcement was random.
If you want to avoid trouble: just ask.

Hello Sandocan
Permeable paving is a nice term. After a few years, nothing infiltrates anymore. It all gets clogged with dirt.
Build in a slope of 2 to 3% (2 to 3 cm per meter). At the end, either install a drainage channel or let the water flow toward the street. But always away from the house. If you get hit by a "hundred-year rain," the street will be flooded anyway. Your 50 m² (540 ft²) won't make any difference then.

Create a 2 to 3% slope. At the end, either a drainage channel or let it drain toward the street. Draining toward the street is not allowed and is at least regulated here by the building authority (building permit / planning permission). Rainwater must generally be managed on the property itself.
My pavement has been installed for 8 years now and it is not clogged. Of course, I also clean it occasionally. The main effect of infiltration actually comes from the joints and not from the pores of the stones.
