Hello everyone,
I want to cover my terrace (partially roofed about 2/3) with 90x90x2 cm ceramic tiles (have it done).
Currently, there is a concrete slab with bitumen waterproofing membrane (as protection against rising moisture from below) and almost no slope.
Current condition:
The 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 bordered, meaning the ends on two sides are "open" and should connect flush with the garden.
How should the further construction proceed?
I have read that one can or should either:
Apply sloped screed and then lay terrace tiles on top with drainage mat underneath
Or
Use drainage concrete wet-in-wet with the tiles. But then you have the problem that water might accumulate on the concrete slab if water seeps through the tiles and drainage concrete?
What should be considered regarding frost protection?
How should the connection at the open ends to the garden be done?
Bullet points sealing, drainage, etc.?
Because if the ends are sealed, possible water can no longer be drained away?
Thank you all.
I hope for some expert feedback
