ᐅ Use Category A and Design Principle C

Hello,

I have a question about building a basement.

Is it possible to build a basement with usage class A according to design principle C, or is that generally not recommended? Or would you actually say that this is the common practice?

I mean design principle C with an additional waterproofing layer already planned.

H10 guideline – waterproof concrete structures.

Thanks for your feedback.

Does no one have an answer to the question?

Let's put design principle B aside for now; it’s too complicated and also not feasible with usage type A.
Design principle A is hardly achievable depending on the building.
So only design principle C remains.

I can’t say much more at this point since you’ve provided very little information.

What would you like to know?

The precast reinforced concrete walls are backfilled on site. So, it is not a precast basement.

Is it a single-family house measuring 10 x 10 m (33 x 33 ft)?

For the semi-prefabricated walls, a crack in the joint is unavoidable and intentional; it is sealed with a joint flashing, as specified in design principle C.

How should "C" be implemented in the floor slab? What was planned?

Exactly, a 10x10m (33x33 ft) house. A city villa.
A coated joint flashing will be installed all around. According to the supplier, this ensures exposure class A and service class 1.

So, there is a part of the slab that "protrudes," and the prefabricated walls will be placed on that. Plus reinforcement bars in the slab extend "upwards" into the prefabricated walls.

What do you mean by how "C" should be implemented in the slab?
