We are in the process of quite substantial work in our hallway. Among other things, the existing staircase will be replaced with one that has tiles.
I can start with a picture to show how the final result should look:
Only the lower part is relevant right now, disregard the upper staircase.
The staircase currently looks like this:
To lay tiles, I have understood that it is strongly recommended that they are attached to a "dead" material such as concrete or lecablock. Therefore, I have sketched a staircase built of lecablock and two cast concrete landings. The problem is that I have no sense of how the landings and steps should be dimensioned to hold well. I found a thread here on the forum where steps were discussed, and the original poster was advised to go with 6cm thick steps with reinforcement near the bottom of the casting. I think my staircase has a bit width, so maybe it's reasonable to add a few more centimeters?
It would look best if I cast the entire width, which is about 2 meters, and then the space under the staircase can be used for storage, but there's really nothing stopping me from placing support in the middle.
A simple drawing showing the staircase from the side. The lowest two steps will be lecablock. Step 3, as well as the landing, I am thinking of as concrete. Support pillars are not drawn in; I am thinking of either casting these in circular pipes or building with lecablock.
