Rear wall brick - damaged and cracked

Hello,

I just inspected the finished masonry work at the construction site (belonging to my mother). Since I am a layperson in this field, I wanted to ask whether the things I noticed are relevant. Please do not answer too roughly. I have already tried to educate myself via Google but basically couldn’t find anything about this. My mother does not have an independent inspector from DEKRA and I’m just asking because it struck me as noticeable.

1.) The rear wall bricks with many cavities are clearly broken in some places, both from the outside and inside, and show visible holes of up to 3x4 cm. (severely indented, broken) up to the first inner stone ribs, which also seem to be damaged.

If these holes and breaks are later "filled with putty," can this negatively affect stability and/or thermal insulation?

2.) In some places there are gaps of up to 2.5 cm wide between the rear wall bricks, not filled with cement and in some places already filled. Does this pose any disadvantages regarding stability and/or thermal insulation? Because as I see it, these bricks should all "interlock" due to their shape?

3.) Impact drilling should not be used with these bricks, but what about nails?

4.) In front of the house lies a "Delta-MS" foundation protection / clean layer. Does this mat go under the screed, which has not yet been laid? Or was it even forgotten?

I’m also asking these questions out of curiosity and so that I can have a say in the conversation with the site manager tomorrow or the day after. :)

Thanks in advance!

It looks like this in about 20 places, and sometimes the gaps between the individual bricks are 2-3 cm wide and either already plastered over or not.

The construction manager said today, "everything will just be plastered over."

I’ll do my best :D

Please convince your mother to involve an independent inspector. Not because the shown pictures would indicate poor workmanship; on the contrary. But so that your questions can be answered in a personal conversation. And by the way, it’s not a bad idea to hire an independent expert as a construction supervisor.

Anyone building with perforated bricks must know that dimensional tolerances of up to 1 cm arise during the firing process, which are later compensated with the plaster. Furthermore, perforated bricks are somewhat more sensitive in handling, tending more to dents and cracks during processing. All no problem and perfectly fine!

Building a house does not mean dying for beauty, but receiving a building free of defects ;)

Rhenish regards

Thanks first of all for the reassuring answer :)

Of course, an independent expert like DEKRA sounds good, as I wouldn’t have to constantly google and ask in forums. Is someone like that paid by the hour? What extra money should be roughly set aside for just over 3 months of construction time? (I’ve already heard amounts between 5,000-10,000 euros) Because the budget is already almost exhausted due to problems with excavation. "Mitteln" was the solution afterwards and much more had to be removed and later also more filled in :S
