ᐅ Base plaster waterproofing: what was used and who installed it?

Hello everyone,
we are building with a general contractor. Today, I was “surprised” to learn that the base plaster waterproofing is our responsibility.
My landscaper says that the exterior plasterer should do it. He can then guarantee the entire scope of his work. In an emergency, the landscaper can also do it.
The landscaper’s quote (about 2000€) is almost twice as expensive as the plasterer’s (1000€). The landscaper seems a bit more reliable to me.
Question:
- Who did it for you?
- With what material (black bitumen, mineral cement, etc.)?
- What is your experience? Is this work so risky (in terms of warranty) that no one wanted to take it on? I don’t want to take unnecessary risks over 1000€.
Thank you for your answers.

As far as I know, the dimpled membrane only distributes the load of the backfilled stones. I’m not exactly sure what you mean.
I wish you good weather for your project next week! I mean position 2 in the image Sockel2 attached.

Actually, the dimpled membrane has nothing to do with waterproofing. According to the sketch in the image Sockel2, you actually have to seal continuously from position 1 to position 2.
In my case (see image SockelBild), it will be about 1m (3 feet) high. The slight difference is that below the exterior plaster there is still a plaster edge. In my case, the second dimpled membrane will overlap that.
I plan to fully waterproof area 1.
Area 2 is questionable.
What do you think?
Thanks for your answers and I wish you a pleasant evening.

fach1werk22 Nov 2020 22:14I can’t help with that. In our case, the dimpled membrane was installed as a single layer. I applied coating up to the chamfered insulation boards, that is, up to the ground slab. If a professional is doing the work, include Heinz von Heiden’s specifications as part of the contract. If your contractor doesn’t follow them, at least you have a solid basis to hold them accountable.

Gabriele Many thanks again for your help and experience. I wouldn’t have done it without you.
Today I started. Haven’t made much progress yet because I was waiting for the weather.
One question: what did you use to mask off the façade and base area? I used crepe tape, and it doesn’t stick well.
What do you mean by “yellow fineliner”?
Thanks and have a nice evening.

Yellow fine liner is painter's slang for yellow masking tape. I like to use the one from kip; the one from Tesa is also fine. It is a smooth masking tape. It does not damage surfaces, peel off paint, or leave adhesive residue, even after several weeks. Don’t use cheap tape; it’s not good. On base plaster, it doesn’t stick very strongly, but it held well enough. You can find it at a paint supply store.
If you want to mark something and have the line remain invisible afterwards, you can also find chalk markers where artist’s paints are sold. These are very easy to use and washable. They are like colored pencils, a pigment core wrapped in wood.

Yellow fine liner tape is painter’s slang for yellow masking tape. I usually prefer the one from kip; the Tesa one is okay as well. It’s a smooth masking tape. It doesn’t damage surfaces, doesn’t pull off paint, and doesn’t leave adhesive residue, even after several weeks. Don’t use anything cheap, it’s no good. It doesn’t stick particularly well on base coat plaster but holds sufficiently. You can find it at paint supply stores. If you want to mark something and the mark should be invisible afterwards, where you find artist’s paints, you can also get chalk markers, which are very easy to use for marking. They can be washed off. They’re like colored pencils, a core wrapped in wood.

GabrieleHello Gabriele, I bought painter’s tape from Tesa and it holds well. Before that, I used 3M (also a well-known brand, right?). However, the master painter recommends the Storch brand. Unfortunately, he only has the small width options (15/20mm).
I need your help again. How would you handle the slope in perimeter insulation? The plasterer sawed it and applied putty today (see photo). Is that enough? Is reinforcement not needed in this sloped area, like it is in the base area?
Thank you for your help.
