Just wanted to hear opinions and answers. Here is the situation. You have done perfect prep and are ready to lay sod and along one side is the concrete driveway and sidewalk. According to what I understand the dirt should be 1-1 1/2" (depending on the thickness you supplier cuts the sod) below the top surface of the concrete. This allows a uniform and level surface from driveway to turf when the sod is put down. I mean it could even be a little above to allow for a little settling and compaction. Lately around my area I have seen MANY sod installs where the entire soil surface of the sod (not the existing soil) is above the level of driveways, sidewalks, etc... Isn't this wrong or am I reading the wrong information.
