This video covers the last few months of work. During this time, we excavated the material at the entrance to the apartment and poured the slab in the same place. The process was complicated by the hole for the coal that goes into the boiler room, as I had to concrete it in advance. The concrete slab is of course waterproofed from below. We also poured a wall in the kitchen, which was open from the start of construction. It didn't go exactly as planned here, as the form was not supported strongly enough and it tilted slightly during the pouring. It will be possible to hide the defect by grinding and plastering.
