ᐅ Upper floor without screed – concrete subfloor only

Hello,

I have visited several developer-built houses and noticed that they construct the upper floor without a screed layer. Friends and acquaintances also sometimes do not have screed on their upper floors. The insulation for, for example, laminate flooring is placed directly on the concrete, with the laminate installed on top.

How should this be approached, considering that developers build the upper floor without screed? Should one be cautious, or is this common practice nowadays?

I would guess that there is some kind of rigid impact sound insulation with the floor covering on top – pipes then run underneath, embedded in a bound screed or similar (?). Heating could be, for example, a wall heating system or an air-to-air heat pump.

Hi,

the houses do not have underfloor heating, and the electrical wiring and related installations are embedded within the concrete. This seems to be an increasingly common practice to save construction costs. Although I cannot imagine that the screed itself is particularly expensive. The concrete is also prepared to be level enough to allow for the installation of impact sound insulation and other floor coverings.

Are the water pipes embedded in the concrete?

Well, they will probably be installed in service shafts and boxes...

However, I would not build without a screed...

But it used to be the same... many older buildings also do not have screed...

How do you install electrical wiring, underfloor heating, and similar systems? Do you mill them into the concrete ceiling?

Regarding the electrical cables: On the upper floor, I have (almost) no cables lying on the floor – and I haven’t milled any chases across the floor for them.

And then where are the cables laid? You probably have wireless power or something like that^^
