Hello everyone,
we currently have the following "project":
A terrace roof was constructed, on the west side of the terrace there was previously an approximately 2m high brick wall, serving as a privacy screen / windbreak, on a strip concrete foundation.
We demolished the brick wall, then the terrace roof builder came and installed the terrace roof. Now we are in the process of preparing the strip foundation so that the terrace roof builder can use it as a base for a glass wall that still needs to be installed. A rail with a total of 4 grooves will be mounted on it, in which a total of 4 sliding ESG glass elements will run. I think you know what I mean.
Now to the actual question: How should the strip foundation be "prepared"? The terrace roof builder only needs a straight, level and load-bearing base.
So far, after the bricks were removed, I have knocked off a layer of mortar on the strip foundation down to the actual concrete underneath.
Then I shuttered the strip foundation on the right and left with boards so that the upper edges of the formwork boards are exactly level. Then I smeared the concrete surface with cement water and immediately afterwards applied cement mortar and screeded it over the formwork boards. That is the current status.
My idea for the next steps would be:
First, apply two coats of waterproof slurry on the cement mortar against rising moisture.
Then cover with porcelain stoneware tiles using a flexible adhesive (PCI Flexmörtel S1 or S2), edged on the right and left by stainless steel tile trims as a finish. And finally grout. After all, it is only one tile wide, the base is 25 cm wide and 3.75 m long.
The terrace roof builder can then lay his rail, but of course will then have to drill through the tiles again. Installing the tiles afterwards will not work, since the rail for the 4 glass elements will be placed quite far on one edge of the strip foundation and then I would only have a few centimeters of base left for the tiles.
Do you think this will work like this? Or is porcelain stoneware not suitable? Otherwise, what should I use and how do I "bond" it with the base?
Rail directly on the base looks a bit "raw" and shabby. Large concrete slabs would certainly be more durable but would also look bad.
