Hello everyone,
I was recommended to come here by a colleague from the Bauexpertenforum:
Topic Terrace CORRECT Construction?:
I want to cover my terrace (partially covered about 2/3) with 90x90x2 cm ceramic tiles (have it done).
Currently, there is a concrete slab with a bitumen waterproofing membrane (as protection against rising moisture from below) and practically no slope.
Current condition:
Terrace has a maximum build-up height of about 15 cm including tiles up to the top edge of the sliding door.
The length from the house wall to the garden is about 5 meters. (because of slope)
The terrace is not edged, meaning the ends on two sides are "open" and should be flush with the garden.
How should the further construction proceed?
I have read that you can or should either:
- apply a sloped screed and then lay terrace tiles on it with drainage mat underneath
Or
- pour drainage concrete wet-on-wet with the tiles.
But then you have the problem that water may collect on the concrete slab, should some seep through the tiles and the drainage concrete?
What should be considered regarding frost protection?
How should the connection at the open ends to the garden be made?
Bullet points waterproofing, drainage, etc...?
Because if the ends are sealed, possible water can no longer drain away?
Thank you all.
I hope for some expert feedback.
