Washout! Is there a good way to backfill under a concrete driveway?
I just purchased a home, and we discovered some water damage to the fill under the driveway and front walk. The driveway still has intact slabs, but a little freezing and thawing and I will have gravel instead. I was thinking about trying to shove paver sand under the slabs, and into the gaps along the sides. I was just wondering if anyone had a better idea, or suggestions on how to get the sand underneath and compacted enough to make a difference this winter.
