Green Roof Layers drawing

C'est ce qu'une entreprise en/au(x) United States recherchait pour leur graphic design

Hello,
I would like to have a simple drawing that represents the green roof components. You can find a lot of design online, I just want my own for my website. Here are some ideas that I like:
Feel free to let your imagination express itself.
The goal is to be very comprehensive for people that discover what a green roof is.
From the top to the bottom:
1. Vegetation (sedums)
2. Growing Media
3. Filter fabric
4. Drainage
5. Protection fabric
6. Root Barrier* (*if the waterproofing membrane doesn't include it)
7. Waterproofing membrane
8. Roof Deck

You will see in the exemples different layouts, please use the one described above.

We don't want to recognise any drainage product, so the idea would be to use one neutral, close to the exemple c.

Thank you!
