We bought a townhouse in Cologne from Interhomes 5 years ago. Now it has come to light that the company forgot the dimpled membrane in the floor, so that moisture is getting into the baseboards. All buyers in the row are of the opinion that this is a defect and must be remedied by the company as part of the warranty service. Interhomes, on the other hand, believes that the buyers themselves should have installed this membrane when they built the terraces. Can someone perhaps give us tips on how to proceed? How can you tell from a finished building that this membrane is missing? Doesn't a house have to be handed over "waterproof"?

Hello,

Not from the finished building, the answer is in the construction description!

Kind regards

Morning! I have my doubts. The dimpled membrane costs practically nothing – and you can't regulate every little detail.

However, it can be assumed that a dimpled membrane is not part of the house but part of the exterior facilities – and if these were not part of the contract, then the matter is settled.

Regards, Tom.

Hmm, as a layperson I would see it that way too. There are dozens of standards, VDA guidelines, "generally accepted rules of technology" in construction that cover almost everything and are often referenced. This topic is not described there?

Hi...

I believed that the [Noppenbahn] is merely a mechanical backfill protection and has nothing to do with waterproofing.
We have a concrete (prefabricated parts) basement with [WDVS] and in the ground-contacting area the [Noppenbahn].

Best regards

Good morning,


I agree with you that not every last detail needs to be specified in a BB; otherwise, it would probably be equivalent to a tender. Nevertheless, I do not consider the indication of the separation of the basement from the soil (e.g. rising damp) to be a "little detail." Following this argument, a BB could also consist of just 2 pages; namely the essential requirements for building construction. The rest results automatically from the applicable technical regulations.


No.

**Dimpled membranes have their fixed place in house construction and have nothing to do with outdoor facilities. They primarily serve as protection of insulated underground components against, for example, rising damp and also as protection against damage from backfilling. Outdoor facilities are actually "only" outdoor facilities: internal access, paths, terraces, garden facilities.
