Basement and Ytong - does it work?!

Yes, I am the one with the wooden cellar. It is wrapped in EPDM (but that really should be done by someone who knows how) and is located on a slight slope. That was the prerequisite so that the water around it has a direction to flow away.

By the way, wooden cellars are more common in America – so it's not a new invention.

And if you put aerated concrete into such a cover, that will certainly work too. The question is, what does it bring? We like our wooden cellar because we've never had moisture and it also smells so good.
Without moisture, aerated concrete works too (it is glued, right?), I already see that as an advantage.

Just ask – you do have a slope as well.

Aerated concrete is, due to structural requirements, the last choice anyway to build a basement. Then there is the water problem. It can certainly be done somehow, but why rush it?

Aerated concrete is, due to structural requirements, in any case the last choice for building a basement. Then there is the water problem. It certainly can be done somehow, but why rush it?

That's not entirely true. Aerated concrete has better compressive strength than some other stones, for example pumice.

With Ytong, you can build 3 floors on top of each other; whether there is a basement below or not does not really matter. There are different blocks with varying compressive strengths, the ones for the bottom are heavier because of higher density. Properly sealed, this is completely fine as long as there is no pressing water. In a specialist forum like this, it is better to avoid bar table slogans like "aerated concrete is the last choice anyway for building a basement due to structural requirements."

Thank you all for the responses, they have already helped me a lot.

That’s not quite right.
Aerated concrete is better in terms of compressive strength than some other stones, e.g. pumice.

It can always get worse.

The risk is still higher, the damage case “major”.

In a specialist forum like this,

This is a user forum, not a specialist forum.

One should better refrain from beer table slogans like “Aerated concrete is the last choice anyway because of the static requirements to build a basement.”

Since I apparently insulted your favorite stone, please name me an even less suitable stone than Ytong for (one-sided!) burying.
We already had pumice.

Because, as you may have read, it was not about impossibilities, but about meaningfulness.
