Trying to determine some information regarding the reinforced concrete slabs (reinforced with mesh) in an apartment, by looking through the holes in the middle of the rooms for lights, I've come across the following situation:
- mesh located at 40 mm from the bottom of the ceiling in the middle of the room (visible in a plastic tube used for the light cables) and mesh located at 17 mm from the bottom of the ceiling nearer the edges.
What I'm seeing might be a different level of reinforcement?
The reinforcement is in 2 directions, but this is the information I can get from what I can see in existing holes.
- the slab height is 140 mm
