My wife wants a patio from our walkout basement. It would be roughly 20x30, run under an existing porch that's 11'ft of the ground. I also have a septic tank that would be covered by whatever base I choose to use. The lid of the tank is about 1/2''in below grade. I feel that I have a few viable options, decomposed granite, pea gravel, or pavers. I suppose I'd use treated timber to outline the space and fill with rock or pavers, and put down a barrier below the rock or pavers to keep grass and weeds out.
