ᐅ Screed / Moisture Measurement / Underfloor Heating / Expansion Joints

Hello forum community,

Since I couldn’t find any answers using the search function or by browsing the forum, and found only sporadic information online, I decided to create a new topic.

I am in the process of buying a condominium and have a few questions regarding the title topic.

The apartment has underfloor heating installed, but it is not yet connected. The building was constructed in 2014, so the screed (I’m not exactly sure what type) has been in place for several months. In the middle of the living/dining room, there is a hole with plastic rods that, I was told, is for measuring moisture later on.

As a non-expert, I asked: Shouldn’t the underfloor heating be run at high temperatures for several weeks to dry the screed, to prevent any cracks once the floor covering is installed?

I was told that there are expansion joints around the edges, so that won’t happen.

Is it possible for the screed to be dry after the “colder season,” even though the apartment has never been heated?

What is correct or incorrect about this statement?

Thank you in advance for your help.

Best regards,
Jerome

You can have the screed heated using a portable heater, which any heating company can provide. This way, you can perform both functional heating and surface drying heating. You just need to keep an eye on the electricity costs.

Ours were exactly 800 € (about $860),...
The floor is already dry – I would first carry out a moisture measurement and then decide on the next steps.
