Hello all, I'm installing a 9x10 patio for a friend and had a question regarding the foundation. I live waaayyyy down in Mobile, Alabama and was wondering if any of you have any experience laying patio foundations in regions that have no freeze-thaw cycle. Our coldest month of the year is Jan, and average temps are 60/40! Is it necessary to lay a 2" sand foundation or can you use a ' skim coat' to simply level the ground in preparation for the pavers (12x12 or 16x16)? It is a very hard yard to access and I'd like to use the minimum foundation possible and still produce a professional result. We have VERY dense clay soils down here if that helps. Thanks!
