    most gardening is done in the top most soil in raised beds and that usually has added soil and compost too. Any contaminants would be deeper.

    Your soil is fine. The problem with building rubble is the bits of concrete and stones. Concrete changes the acidity of your soil. Just pick out bits of concrete and stones and any other rubbish you find and it should be fine.

        just get as much as you can out bit by bit, concentrate on the small bits first as they have greatest surface area to interact with water and your soil

          I’d have to get the grass torn up first and don’t think I’ll be able to alone. When I first came here I put weed mat down and then creeping grass came in from under a neighbours fence and took over, grew right through it
