Hello to all the builders in this forum.
For some time now, I have been following the various posts about building here with great interest.
Now I want to make use of the nice weather to start several outdoor projects at my home.
Currently, my entrance area has an old granite slab with an outdated pattern. I would like to replace it with a concrete platform including a coating (gravel gray). In theory, I imagined pouring a concrete foundation and then covering it with a coating or slabs. However, I have several questions concerning the execution.
Question 1
How deep should a foundation for such a platform be? (I have read about 80cm (31 inches) due to the frost line)
Question 2
Does the foundation need to be filled with gravel or aggregate and reinforced with reinforcing mesh?
Question 3
Should there be a slope of 2 degrees to allow water to drain away toward the front door?
Question 4
How should the edge at the door be finished? There should be a watertight transition between the door and the platform.
(ETICS panels, protective coating, drainage membranes)????
Question 5
Is it absolutely necessary to install a screed reinforcement mesh and a drainage pipe within it?
What do you think? I would be very grateful for your opinions, ideas, and creative suggestions.

trendyandi27 Apr 2020 11:41I have also been working on our entrance platform recently... Here is the current status:
I actually have a question about this as well. Our neighbors also had a platform poured.
The structure was as follows:
normal soil
then 30-40cm (12-16 inches) of sand
about 20cm (8 inches) of concrete with steel mesh.
Now, what I find curious is that the steel mesh was actually partially drilled into the brickwork. There was also no damp-proof membrane or anything similar between the front door and the concrete.
No machinery was used, at most a hand tamper. Now I wonder if the entire platform might settle over time and then pull on the brickwork, since the steel mesh was incorporated there.

the part then hangs on the facing brickNon-expert answer:
That sounds about right, yes.
However, there are (probably) many construction defects that go unnoticed because they don’t cause any problematic consequences...

Place boundary stones all around and fill with gravel, then add some crushed stone, and finally lay the porcelain stoneware tiles on top.

Set boundary stones all around and fill with gravel, then add some crushed stone, and finally place the porcelain tiles on top. As you can see in the picture, I have finished the edging and the "crushed stone base" at the platform. Once our paving stones for the driveway arrive, both the driveway and the platform will be paved... Until then, I have laid wooden boards on the platform.
