ᐅ Planning a Ground-Level Patio with Slope – Any Experiences?

Hello everyone,

We have a terrace that measures 3 x 5 meters (10 x 16 feet).
If we roof the entire area, it could be 7 meters (23 feet) long, but that is not currently planned.
My question is in which direction we should create the slope. I would make it slope to the left, with a 2% gradient.
This means the slope would lead away to the left when stepping out from the patio door.
So far, so good...
The precast company requires us to install a drainage grate at least 30 cm (12 inches) wide starting from the door. This grate should have a 2% slope toward the front.
Now the question is whether the grate should also have a slope to the left.

Thank you very much for your help!

The prefabricated components company specifies this for us
What kind of company is that?
And may I ask: why a drainage channel, if everything is generously covered anyway?

Yes, I was wondering the same.
Elk.
They even included a representation in the construction plan.
Here with a setback step.

Cross-section of a foundation build-up: foundation, plinth, gravel bed, lean concrete, slab.

Build a wooden deck. That way, you can safely skip gutters and slopes.

Yep... this complete sealing of plots with stone and paving really doesn’t look good.

During heavy rain with wind from the "right" direction, slopes and gutters won’t help much either. Especially since the water in the corner can’t drain sideways if the wind comes from ENE.

And the kids can place round objects on the wooden deck without everything rolling into the garden.

In high summer, you can’t walk barefoot when the sun is shining on it. In winter... well, that’s up to everyone to decide for themselves...

Don't build a wooden deck. Looking at the wooden decks in the neighborhood, I'm glad I don't have one...

With a little maintenance, no problem.

Do you have one? If yes, please share a photo.
I could still accept hollow-chamber WPC decking, but wood needs to be sanded and oiled eventually, etc.
