Hello everyone,
We currently have the following "project":
A terrace roof was built, and on the west side of the terrace there was previously a brick wall about 2m (6.5 ft) high, serving as a privacy screen and windbreak, on a strip foundation made of concrete.
We demolished the brick wall, then the terrace roof installer put up the terrace roof. Now we are preparing the strip foundation so that the installer can use it as a base for a glass wall that still needs to be installed. A rail with a total of four grooves will be mounted on it, in which four sliding tempered safety glass (ESG) panels will run. I think you know what I mean.
Now to the actual question: How should the strip foundation be "prepared"? The terrace roof installer only needs a flat, level, and load-bearing surface.
So far, after removing the bricks, I chipped off a mortar layer on the strip foundation down to the actual concrete beneath.
Then I shuttered the strip foundation on both sides with boards so that the top edges of the shuttering boards are perfectly level. After that, I applied a cement slurry to the concrete surface, then immediately applied a cement mortar on top and screeded it off against the shuttering boards. This is the current state.
My idea for the next steps would be:
First, apply two coats of waterproofing slurry on the cement mortar to protect against rising moisture.
After that, cover it with porcelain stoneware tiles fixed with a flexible tile adhesive (PCI Flexmörtel S1 or S2). On the right and left edges, the tiles would be framed with stainless steel tile strips as finishing profiles. Finally, grout the joints. Since this is just one tile wide, the base is 25 cm (10 inches) wide and 3.75 m (12 ft) long.
The terrace roof installer can then place the rail on top but will have to drill through the tiles. Installing the tiles afterward will not work because the rail for the four glass panels is positioned close to one edge of the strip foundation, leaving only a few centimeters of substrate for the tiles.
Do you think this will work? Or is porcelain stoneware not the right choice? What else should I use, and how should I bond it to the substrate?
Putting the rail directly on the base looks a bit "rough" and shabby. Thick concrete slabs would certainly be more durable but also look unattractive.
