I didnt know where to ask this question so I thought I would try here
Anyway I have river rock backfilled all around the foundation perimeter and over the french drain ect...and my next step would be to put some dirt over the river rock which would be protected/separated with landscaping material and then sod. My question is why not lay the landscaping material down and then something like foam board or bubble wrap (under concrete type) and then continue filling with river rock lets say 2 feet wide around the house ?
Is this a bad idea ? Less moisture against the house and less grass against the house. The rock is currently sloped away from the house for proper drainage.
