Membrane is placed over packed soil
(thelemmy.club)
Step by step :)
I now have one last water evacuation to place where the exterior faucet is and the. I can lay the metal wire mesh.
So it's all sitting on a layer of small rock so water would drain well. And I'll be making a slope in the concrete so the water should get right at the end of the pad where I'll be making a franch drain / rock walkway to make sure nothing pools too much. Additionally my roof is overhanging quite a bit so the ~40cm are most of the time dry when it rains anyway unless rains gets sideways twice every 5 years or so.
That membrane is water permeable?
As much as the concrete I will pour… but the sides where water can seep through will have a permeable layer. Between the walls and the pad. And the layer below the membrane sure is permeable.
