We are installing paver for the backyard. The based rocked are already laid on the ground by the contractor. I asked the contractor to leave a foot of open space around the house for planting (small shrubs or flowers). The structure on the right side of the pic is the garage. The foundation is exposed right now. If I fill the trench with gardening soil leveling to the paver (3” above the based rock), will I create moisture issue for the walls?

If yes, in order to resolve this issue, should I dig deeper, and then fill in the gardening soil. So that the top of the filled soil will be couple inches lower than the paver.

Please help, your opinion is very valuable to us.Thanks!
