Planziegel - Butt joint technology with fabric tape?

Evening,

I was at a shell construction site with the family today. A single-family house is being built there with Poroton bricks. The exterior walls were more or less finished.

I noticed that at the spots where the interior walls are to be built, every 2-3 rows about 15-20 cm long (and about 5-6 cm wide) plastic mesh strips were sticking out of the wall. I thought steel bands are normally used there?! Is that allowed? Unfortunately, I couldn't find anything on the internet.

Thank you for the question, I have not encountered that either. It's a pity that you did not attach any pictures.

Simply consult the processing instructions of the manufacturer.
