Clean Fill Dirt #1 vs Fill Dirt #2

Clean Fill Dirt #1 is screened and debris-free; Fill Dirt #2 is unscreened. Use #1 under slabs, sheds, and pads, and #2 for raising grade and bulk fill.

The difference is one word: screened. Clean Fill Dirt #1 is screened and debris-free; Fill Dirt #2 is unscreened and may contain roots, clay chunks, and other material from the dig. Use #1 anywhere the dirt sits under something important, and #2 anywhere you just need to move grade cheaply and in bulk.

What Clean Fill Dirt #1 is

Screened fill dirt, free of debris. It compacts evenly and predictably, which is what you need under slabs, sheds, pavers, and clean pads. Because it is uniform, it settles less and compacts to a firmer finish than unscreened fill.

What Fill Dirt #2 is

Unscreened fill from excavation. It still does the job of raising grade, filling low spots, building swales, and backfilling, but it is not uniform and can contain organics that decompose. Never use it under anything structural.

How to choose

  • Under a slab, shed, or pad: Clean Fill Dirt #1, compacted in lifts.
  • Raising a yard or filling a dip: Fill Dirt #2 is fine and economical; overfill slightly where settling is acceptable.
  • Growing anything on it: whichever fill brings you to grade, then 2 to 4 inches of topsoil blend on top.

Both are delivered by the cubic yard with a 4-yard minimum. See Clean Fill Dirt #1 and Fill Dirt #2 for details, estimate your yardage with our material calculator, or request a quote.

Frequently asked questions

No. Unscreened fill can contain debris and organics that settle or decompose, which leads to voids under the slab. Use screened Clean Fill Dirt #1 and compact it in lifts for anything structural.
Not by itself. Clean fill is screened but it is not soil with organic matter and nutrients. If you want to plant, put fill down to reach grade and top it with 2 to 4 inches of topsoil.
It can, because unscreened material is less uniform and may contain pockets of organics. Compact it in lifts and overfill slightly where settling is acceptable, like swales or backfill behind walls.
Measure the area and the raise in inches, then use the yardage formula: length x width x depth-in-feet / 27. Our material calculator does this in one step.
Moderately. Fill dirt is finer than stone and holds water longer. In South Florida's rainy season, grade it so water runs away from structures and consider drainage stone where water collects.
