Solid construction method with expanded clay.

Hello,

can someone share their experiences with the mentioned construction method?
What are the disadvantages of this construction method?
There is not really much to find about this, only positive aspects are always mentioned, even in various forums there is little information about it.

Regards C.

Lightweight expanded clay aggregate is not at all a "construction method", but a wall building material (stone) that, similar to pumice or aerated concrete, is suitable for monolithic walls and is sometimes offered as a "stone" and sometimes as a wall panel.

Please explain the context or background of your question. Your thread history suggests you have received shell construction offers and now want to know if another stone would be cheaper? - for that I have the rather well-known mantra here: do not use any stone your builder is not accustomed to.

The background of my question is definitely not about whether costs can be saved with the "construction method". It is simply about whether anyone in this forum has experience with this "building material" or maybe knows something about it. We want to build, yes we have received offers. Now, however, a much cheaper building plot has been found in a different catchment area. There is a construction company here that offers conventional brick-by-brick building and the variant with clay aggregate prefabricated walls. When you look at various websites, clay aggregate has many advantages, but where are the disadvantages, not much can be found about that! And please stop accusing people of wanting to save money when a simple question is posted!

Then build with lightweight expanded clay concrete or not with this company. I live in the heart of a pumice region, hardly anyone builds with lightweight expanded clay concrete here (because the two are too similar and we have pumice here like sand on the sea or coffee in Brazil). Regarding similar pumice, I can tell you that I have been living happily in that material for five decades (in several houses).
