Correct execution of exterior wall to ground slab

Hello everyone,

since quite a few things have already gone wrong with our new building, I would like to ask for advice/info regarding the execution of insulation/sealing between the exterior wall and the base slab.
Construction:
- Frost skirt, on which the base slab is poured
- Inner wall 1st and 2nd course on horizontal barrier
- 16 cm insulation
- Brick veneer
On the internet, I found the attached drawing, which (except for the frost skirt) matches our construction.
The following questions:
1. Is the depicted construction correct or are there better options?
2. A perimeter insulation is installed in front of the end of the base slab – how deep should this be applied? Is it sufficient to reach the bottom edge of the base slab or how deep and what thickness?
3. How and how deep should the end of the base slab be sealed, and what is best to use (sealing slurry, torch-on membrane, etc.)?

Unfortunately, our architect is leaving us "hanging" with these detailed questions.

Thank you to everyone who takes the trouble to read my text and possibly respond.

Best regards
Ralf

Good evening,

I cannot impress with deep expertise, only with how we handle it in the company.

To my knowledge, facing bricks do not belong on the floor slab but on the foundation. Below them, masking is applied as shown in the drawing. I have never heard of water-repellent mortar nor that it is used. Otherwise, I don't find it wrong. Open butt joints must be placed at the top for drainage, but usually, joint ventilators are installed to prevent too many creatures from getting in. Placing some at the bottom is also not wrong.
