I’m going to hire someone to demolish and remove my concrete backyard. Do I need to leave a certain amount around the foundation? Of course this complicates it as they will have to use a concrete saw. There is one drain, should I try to keep it? Or will I no longer need it?

  1. Thanks for all the advice. Right now all the water goes into the drain (connected to waste pipe). The problem aesthetically is that I have an L-shaped backyard so I would have to leave concrete around the whole house not just where the drain is which is at the back (guess this is just what I am going to have to do). The yard is prob. about 200 sq ft.

  2. we removed cement and laid brick over sand for about 2 feet from the building, sloping away from foundation, and this worked fine. we had an engineer look at it for about $300, but his advice was pretty simple. I’d think the drain would be good to have, but depends where it is in the new landscape.

  3. when I removed the concrete from my yard, I left a 10-foot buffer from the back wall, and left the drain intact. No foundation problems so far. How deep is the yard?

  4. Can you describe the overall drainage conditions of the yard as it currently exists? During a heavy storm, what do you see happening with the water?

    If done correctly, the removal of the concrete should allow for drainage to occur naturally into the soil. But your concerns abour closer to the house are warranted. If the concrete is directing water away from the house and into the drain, the removal of the concrete may necessitate a french drain along that portion of the house, to keep the foundation from leaking (stone or more modern masonry block?). Is the runoff from the roof thoroughly collected by the gutter and drained into the sewer pipe, especially during the really heavy rains?
