Use the dirt for inner layers but try to use some quality soil for the outermost layer. If you just don't have any good soil to use try growing things like comfrey & buckwheat & legumes & other things like that which will eventually improve the soil if they are chopped & dropped in place. Earthworms, manures & compost will help too.
Argue for your limitations and they are yours forever.
