I can't find the designation for my floor structure, so I'd appreciate some clarification. I'm about to install underfloor heating and therefore need to understand the function and load-bearing capacity of the bottom slab.
The house is a link house from the 1960s with a crawl space.
1. Top slab 8-9cm where the floors are currently located.
2. Intermediate layer that looks like crushed lightweight concrete. 13 cm. This is where all the piping runs.
3. Bottom slab heavily reinforced, looks like cast concrete blocks from what I can see from the crawl space. 5cm.
Is this a floating floor and if so, why is the bottom slab thinner than the top slab?
