Hello everyone,

I have a topic again where I’m stuck and hope to benefit from your collective knowledge. Of course, I’ve already done some research online, but I’m still not sure about the right approach.
Our landscaper is unfortunately taking a long time to prepare the quote. So, I thought I might try to install the splatter protection myself.
Our house has a basement. Recently, an external thermal insulation composite system (ETICS) was installed, ending roughly at the top edge of the basement windows. The lowest insulation panels are wedge-shaped, getting narrower toward the bottom. The landscaper said he would use a drainage membrane (dimpled membrane) there.

Question 1: What is the purpose of the drainage membrane? My understanding is that it protects the ETICS from damage by stones?

Question 2: Is the drainage membrane attached to the house somehow? My idea was to extend it slightly lower than the ETICS so that it stays in place due to soil pressure. Does that work? Will a few centimeters be enough?

I only need splatter protection on two sides of the house. On one side, there is already a concrete edge. After installing the drainage membrane, I would fill it with soil, then lay landscaping fabric on top, followed by gravel. On the other side, a new edge needs to be built. For this, I’d like to use existing paving stones.

Question 3: How do I build an edge with paving stones for the splatter protection? Probably best with concrete. How do I do that?

The garages also need splatter protection. There is no ETICS here, and so far, there has been little to no splatter protection. For about 50-60 years, soil has been directly against the garage foundations (or in one garage, there is some very thin insulation attached).

Question 4: Should a drainage membrane be installed at the garages? I don’t see a reason, since there hasn’t been one before.

Well, this turned out to be quite a long message. Oh yes, I’ve also attached photos.

3.+4. With a bit of imagination, you might see the wedge-shaped insulation here.

Thanks in advance to everyone who has read this far!

Good point, I hadn’t noticed that. And where there is no insulation, like in the garage?

No idea. Probably less is enough...

I read earlier on a blog that the person only used 5cm (2 inches) of gravel. I was just concerned about how much I need to excavate, and I’ve easily got that covered 😀

Update: We tried working on the garage and reused some existing bricks. I haven’t bought any gravel yet; I read that it’s better to order it than to buy it at a hardware store.
We still haven’t agreed on an edging stone for the house. I don’t like the standard ones, but I can also understand my husband’s point that the paving stones are too elaborate.
