Paver clinker sealing grade

Hello everyone, I would like to know what level of sealing normal paving bricks have? Do paving bricks belong to partially sealed surfaces and have a sealing level of 0.7 or even 0.5? The [Baunutzungsverordnung 1990] applies

The Baunutzungsverordnung has nothing to do with sealing. Normally, when it comes to paving, it’s about the joints – something like that is stated in the development plan, how your municipality would like it. Brick alone doesn't help, it doesn't allow infiltration. Or what exactly do you want to know?

There is nothing stated in the development plan.

So it varies from municipality to municipality.
Would have to inquire with the municipality then.

Thought there was a general regulation for something like that.

The decisive factor is indeed the current development plan. If there is nothing stated there, you can do anything.
