ᐅ Basement and aerated concrete blocks – does it work?!

Hello everyone,

I am planning the construction of a house with a partially basemented area. The house is built on a slight slope, and the rear half directly adjoins the soil. This means the earth is exerting pressure on the house, and rainwater will likely flow toward the building.

So far, I have spoken with structural shell contractors who work with Poroton masonry. Without exception, they all immediately said that the area in contact with the soil should be formed with cast concrete. That seemed reasonable to me as well.

Recently, I visited someone who plans to build their entire house using a Ytong kit, and their colleague mentioned that it is also possible to build this area with Ytong blocks or that there are solutions available for that.

In general, my question is: What do you think about basements made from Ytong blocks? Are there specific Ytong systems designed for basement construction? Or should this approach be approached with caution?

What is interesting is that this colleague is a certified structural engineer and will definitely handle the structural calculations himself (we have done the plans with an architect who is supporting us through the building permit / planning permission process).

Best regards
