ᐅ Question about aerated concrete and site conditions

Hello,

I have looked into various building materials and ended up focusing on aerated concrete.

I have already gathered some information online about its advantages and disadvantages.

The biggest drawback seems to be its susceptibility to moisture and heavy loads, right? Does that mean the material tends to absorb moisture easily and releases it poorly?

How is this during the construction phase when it suddenly rains, since the material is left exposed or partly installed? Does this cause any problems, or is rain generally not that harmful?

Is there any strong reason to question the use of this material besides the moisture issue?

Regarding the plot of land:

Assuming I have a very flat plot there, which will be newly surveyed, etc., what needs to be done before construction starts? For example, should the soil be compacted, or do boreholes need to be made?

What kind of costs can arise up to the start of construction, excluding land transfer tax, registrations, notary fees, and so on?

Best regards

PS:

I have an appointment with my house bank on Monday to see what is financially feasible, and next Friday a meeting with a representative from the IBG-Haus company.

Is there a kind of checklist available here on the website or specific questions that should definitely be asked?

Thanks in advance

Hi,

the idea of a list of questions is a good one, I did something similar when I went to the bank.

You should write down questions about prepayments, as that could be important if you get some money or want to make an extra repayment.

Aerated concrete is moisture-absorbent

It tends to soak up water easily. I would cover the material packages and wall tops with tarps. If necessary, I would use construction dryers.

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

Costs incurred
- Notary
- Permits (building permit / planning permission)
- Connection fees (electricity, gas, water, etc.)
- Surveying
- Soil testing
- Earthworks
- If needed, sidewalk protection
- Building permit

Hello,

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

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

However, he avoided answering my question about which Poroton brick it is.

He said that Poroton has the disadvantage that when installing pipes, more chambers than necessary often break, which can lead to thermal bridges.

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

Well, we’ll see ^^
