Either way, the profile before compaction won't be the same as the profile after. Spreading dirt in the holes may look level, but the new dirt will compress more than the existing (read: already compacted) dirt. Several passes of new dirt, compaction, new dirt, compaction, etc. might get you there, but it won't be the same unless you really go to town on it.I hope!
Now on another note, can anyone generally tell me if filling low spots in a yard, will a pallet drag work to smooth the dirt before compaction? Or is it worth it to buy one of those metal chain looking drags like they use for a baseball infield (the kind with no added weights)? I want to dump dirt in the low areas with a shovel and do a rough rake and then let the drag do the rest of the work...no tedious finish hand raking if possible? I am gonna roll it with 400lbs after I drag it too.
Thanks!
At a previous job, I watched some compaction in preparation for erecting a new building. They brought in a crane of at least 100', ran a weight to the top that (based on estimated size and likely composition) must've weighed dozen tons or more, then let it freefall until impact. They did that over and over again for weeks. That was uniformly compact, or close enough for government work, anyway.
Granted, you don't need that level of uniformity (or of compaction, for that matter), but a couple of passes with a roller won't give you a long-term level surface. You need to either pound the daylights out of the new dirt, or till everything (to fluff it fairly equally) and then roll it all out (to compact it equally), to get it to be flat and level for the long term.
