Slab sheeting termination for new slab in existing crawl space
I have an existing crawl space that I will be pouring a new floor slab to convert for storage use. Climate zone 5. I am following a condition basement approach which the walls will have 2″ continuous foam and batt to R 15. The under slab will have 2″ XPS. My question is how to terminate the underslab vapor retarder which will be 10 mil sheeting. Is the attached diagram correct with turning the sheeting up and seal to the vertical stemwall XPS? If this is done, should the stemwall to underslab XPS junction be left unsealed?
