Hello,
we are currently building as well. In the next few weeks, the screed will be installed.
Our builder now wants to place three construction dryers in the house for two months afterwards. However, we would prefer to avoid this and get rid of the moisture by ventilating. The builder advises against this.
Can anyone give us advice on whether construction dryers are really necessary or if it is possible to manage the moisture without them?
Thank you in advance for your opinions.
Best regards,
steffi23

Christian AHS14 Dec 2013 13:44Hello everyone,
our screed has now been in place for 4 1/2 weeks.
Because the utility provider was unable to install the supply lines into the house due to illness, we have only been heating since last Friday (so eight days so far) using a "HotBoy" connected via bypass to the heating circuit with a 22kV instantaneous water heater—you can almost hear the money flying away.
However, we are now at around 20°C (68°F) inside the house and I’m hoping the chimney sweep will inspect and approve the gas boiler on Monday or Tuesday so we can switch to normal heating operation.
Currently, we ventilate three times a day—morning and evening by me, and at midday by my wife.
This definitely helps—as you can see from the condensation at the opened fogged-up windows, showing what is condensing or now escaping.
I’m curious whether we’ll be able to install the floor coverings in calendar week 10/2014.
How is it behaving in the garage? The protective foil in front was severely shredded after one week due to the storm—but for about three weeks now, there have been no dark stains on it.
My plan here is to lay battens and then place moving boxes and packaged new furniture on top so air can circulate underneath—is that a good idea, or would it be counterproductive given the remaining moisture?
Best regards,
Chris

Christian AHS27 Dec 2013 22:12Hello everyone,
The screed has now been there for six weeks and has only been effectively heated for about four weeks (due to a delay with the utility provider for the house connections caused by illness), without underfloor heating.
I find it a bit insufficient that the heating is only reaching about 19°C (66°F) inside the house – shouldn’t it be much warmer? We are ventilating twice a day during the holidays.
I also placed chemical room dehumidifiers (up to 80 cubic meters) in each of the upper rooms and have collected around four liters of moisture so far. I am considering renting an electric dehumidifier, something roughly the size of a “backpack for outdoor use” or “refrigerator-sized.”
Today, I bought a simple residual moisture meter from the hardware store. It shows 0.5% at the screed in the basement, 0.6% on the ground floor, and 0.7% on the upper floor.
As far as I understand, this is only an indication, and an accurate measurement can only be obtained if “core drilling” is performed at several points in the screed and the core samples are analyzed, is that correct?
Regards,
Chris

That is correct. For underfloor heating, these spots are marked in advance. A small rod is inserted there to avoid drilling into any pipes.

From my personal experience, I can only recommend renting and setting up (several) dehumidifiers at this time of year. The screed heating program of your underfloor heating goes through several phases, so it will get even warmer (you will feel like you are standing in a sauna). A hygrometer is also a good investment; according to our building expert, you should always try to keep the relative humidity below 50% when ventilating, if possible.
