Proper commercial site grading and backfill requires a clear understanding of the civil engineer's grading plan, access to the right equipment for the scope of work, and a disciplined approach to compaction testing and quality control at every lift. Grading has to achieve the design elevations within tight tolerances — typically within a tenth of a foot — so that concrete forms set on top of the graded surface come out at the right finished elevation without costly adjustments. Backfill material has to be placed in controlled lifts — typically no more than eight to twelve inches per lift depending on the compaction equipment being used — and each lift has to be compacted to the specified density before the next one goes down. Skipping lifts, using the wrong fill material, or failing to test compaction are the mistakes that show up later as settled slabs and cracked flatwork. Solorio's Construction integrates site grading and backfill directly into our commercial concrete scopes — serving clients across Athens, Dalton, Augusta, Chattanooga, Birmingham, Greenville, Greer, Clemson, and right here in Gainesville — so the earthwork and the concrete are coordinated by one experienced crew from start to finish. When the site has to be right before the concrete goes down, this is the team that makes it happen.
