How to fix the situation if the stairs are not properly concreted?
Revision 1
Our staircase was supposed to be the centerpiece. It is concreted and we have made the coating in self-performance of the known carpenter.
Actually, according to the construction plan, the stairs should be concreted up to the upper floor. Unfortunately, the last step was "forgotten" and now we have as the last step concrete, polystyrene, screed and tile with underfloor heating. The construction company thinks that was just so handhabe of the concreter and is fine. Since we wanted to make the stair covering itself, we must take care that the conclusion is beautiful. We find absolutely no way to make this end of the stairs rudimentary beautiful, let alone stable. The tiler of the house company would not help us because he could never give a guarantee on the conclusion.
What to do? We want to make the stairs below still with concrete optic plaster under the steps.
