Hello,
we plan to start building the terrace next week. We are getting 1.2 x 1.2 m (4 x 4 feet) ceramic tiles. The terrace will measure 9 x 4.2 m (30 x 14 feet).
Both the living room and the kitchen have sliding doors that provide level access to the terrace. There will be a small step of 2 cm (0.8 inches) once the tiles are installed. The terrace faces west.
The DIN standard requires a drainage channel in front of the sliding doors. I would prefer to omit this. What slope should the terrace have? 1% or 2%? I’m leaning towards 1%. The rest of the property is on level ground, with no slope.

This was an example for the "stable" drainage channel; you then click on the grate, and the price will appear below in the display.

A 1% slope without a channel turns your living room into a perfect infinity pool leading to the terrace during heavy rain. 😀

I see negligence in the entire setup, including the missing joints on the 120 x 120 cm (47 x 47 inches) tiles.
