I am doing an extension. Today, I poured a concrete slab and then built up a foundation wall with lecablocks. I am building a crawl space. Now I plan to plaster the surface (slamma) to prevent water from penetrating the lecablocks. Then my plan was to place external insulation around the entire wall. There is also insulation under the concrete slab. How should I proceed? Should I attach, for example, minerit baseboards 8mm as an external cladding that also serves as protection? Or are there any other suggestions? I would like the outer wall insulated to really frost-protect the foundation.
