ᐅ Is Reactive Waterproofing Better than Thick Bitumen Coating?

Hi,

I am planning to reseal the exterior basement wall, which is about 5 meters long (16 feet). Now I am considering which option to choose: reactive sealing or bituminous thick coating. Are there any practical experience reports on this? Reactive sealing is said to have advantages in application, but is it really recommended? For example, WeberSuperflex d24 or Mem Express dicht.

Bitumen, on the other hand, has a proven long-term track record.

Modern engineered materials versus materials used for centuries.
Both, however, ultimately achieve the same result.

However, if I have read correctly, reactive (fire protection) is not approved according to the relevant DIN standard.

No, reactive sealing complies with the standards and is even mandatory for monolithic buildings (base), since plaster does not adhere to PMBC.

So, can I use Weber reactive waterproofing or Remmers without any concerns and not worry that it will perform worse in the long term compared to the well-known traditional bitumen?

You can do both. First apply the mineral-based layer, then the base coat plaster on top, and finally the PMBC on the parts in contact with the ground (which you don’t see). That’s how it was done in my case.
