Question about the building material aerated concrete and the property condition

Hello,

I have looked at various building materials and ended up with aerated concrete.

I have already gathered some information from the internet about its advantages and disadvantages.

The biggest disadvantage is probably its susceptibility to moisture and heavy loads, right? Does that mean the material tends to absorb moisture and release it poorly?

How is it during the construction phase when it suddenly rains and the material is left unprotected or partially installed?! Does that cause any problems or is rain basically not that harmful?

Is there a strong reason to question the material besides the moisture issue?

Regarding the plot of land:

Assuming I have a plot that is very flat, will be newly surveyed, etc., what needs to be done before the start of construction, meaning does the ground have to be rolled first, or do boreholes have to be made?
What costs can arise besides property acquisition tax / registrations / notary, etc., up to the start of construction?

Best regards

PS:

I have an appointment at my house bank on Monday; we will see what is financially feasible, and next Friday an appointment with an employee of IBG-Haus Gesellschaft.

Is there actually some kind of questionnaire here on the homepage or questions that one absolutely should ask?

Thanks in advance

Hi,

the idea with the questionnaire is a good one, I did something like that too when I went to the bank.

You should write down questions about special repayments, that could be important if you get money or want to repay something outside the usual schedule.

Aerated concrete is water-loving

It therefore soaks up moisture easily. I would cover the material packages and wall heads with tarpaulins. If necessary, I would work with construction dryers.

In solid construction, it is also advisable to properly dry the building before the external thermal insulation is installed.

Costs incurred
- Notary
- Permits
- Connection fees (electricity, gas, water, etc.)
- Surveying
- Soil samples
- Earthworks
- if necessary, sidewalk protection
- Building permit

Hello,

thanks already for the comments. I had Schuckhardt Massivhaus visiting us this week.

They use aerated concrete and Poroton bricks and at the same price, so I can choose.

Although he avoided my question about which Poroton brick it is.

He said Poroton has the disadvantage that when installing pipes, usually more chambers than necessary break, and this can cause thermal bridges.

Therefore, he recommends aerated concrete but also clearly said it is easier for the masons to work with.

Well, we'll see ^^
