Hello everyone,
this is about the method our house builder is using to create a waterproof basement. To be honest, I have never heard of this before, and there is very little information available online about it... and what there is mostly relates to commercial or office buildings.
The method is called "fresh concrete composite membrane" (FBVK #waterproof) with double-layer exterior walls 20cm (8 inches) thick.
One step down would be the "WU-basement" with double-layer exterior walls 24cm (9.5 inches), joint flashing. Of course, this option is also cheaper (approx. 3,000 €).
The plan is to set up a home office in the basement. Therefore, we would prefer it to be "properly sealed," ideally without high humidity caused by water-resistant concrete.
A soil report is not available yet!
Are you familiar with the first method? Have you had any experience with it or any opinions?
It would also be interesting to know whether insulation is possible at all if there is a "membrane" facing the soil on the outside.

Bergblume6 Jul 2024 19:54Hello, we are currently facing the same decision with Schwörerhaus. Are you satisfied with your basement? Did you choose the waterproof concrete (WU) version or the fair-faced concrete (FBVB) option? Do you have living spaces in the waterproof (WU) basement as well? Is a ventilation system needed there because of moisture?
