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.

sven.conzi13 Jul 2017 09:37We are building without a basement, but according to the building plan, we need to create a watertight and gas-tight concrete slab. Our expert recommended the Preprufe fresh concrete waterproofing system. The architect included it in the plans. Just try searching for Preprufe.
Hello, I am familiar with the waterproofing method using fresh concrete composite membrane, but I have no practical experience with it yet!
Why choose such a complex and expensive solution if you don’t even know what the load case is?
For the load case groundwater and usage class A, a waterproof concrete structure with an additional vapor barrier seal is perfectly suitable!
Best regards.
