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 a bitumen waterproofing membrane (as protection against rising moisture from below) and almost no slope present.
Current condition:
The terrace has a maximum construction height of about 15 cm including the 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 the slope)
The terrace is not framed, 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 a sloped screed and then lay terrace tiles on top with a drainage mat underneath
or
- lay drainage concrete wet in wet with the tiles. But then there is the problem that water might collect on the concrete slab if some 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 made?
Bullet points sealing, drainage, etc...?
Because if the ends are sealed, any possible water can no longer be drained?
Thank you all.
I am hoping for some expert feedback.
