Properly establish the slope of the terrace

Angled C does not bother us, the terrace, including the covered area, has a depth of 4.80m. We have already tried placing our garden furniture. In the covered area, we would work with 0% slope to avoid any edge.

We also have a depth of 4.60 m, we sometimes sit with 12 people at the table, as a shade provider we have an electric sun sail above it

Ah interesting, do you have an edge at the floor-to-ceiling window due to the slope?

Yes, 2cm at the right door, with you the highest point would be under the porch roof. Definitely lay with a slope everywhere, the water must run away from the house during driving rain. The doors and windows are not submarine windows. If water stands on the outside, it will also run inside.

Definitely lay it everywhere with a slope, the water must run away from the house during heavy rain.

That is nonsense. The water – even during heavy rain – runs away between the decking boards. Below that, it of course has to be drained. Try to see how much water remains on a horizontal board. There are no puddles.

That is nonsense. The water - even in heavy rain - goes away between the planks.

Ahem, we have a closed deck, so seals between the planks.
Because no dirt gets in there,
no weeds come out, nothing disappears that falls down
