About this fill dirt

Screened fill dirt free of debris, for raising low ground and backfilling. Structural material, place it in lifts and compact as you go.

I contacted Mulch Mound for #57 river rocks and it was easy and fast to get a delivery right before the holiday weekend. Stone was delivered as promised and place exactly where I asked. Excellent service! I will be ordering mulch next!

Fill dirt is sold by the cubic yard, and one yard covers about 54 square feet at a 6 inch depth. Most jobs run a 6 to 12 inch fill depth, so a small low spot might only need a yard or two, while backfilling around a foundation or pool wall can run into double digits. Measure the area you are filling and the depth you need, then work backward from the 54 square foot figure to land on a yard count.

A yard is approximately 27 cubic feet. As a general guideline, one yard of material can cover an area of about 100-160 square feet at a 2-3 inch depth.

Most fill dirt jobs finish with a cap of topsoil once the fill is compacted, especially if grass, beds, or anything else needs to grow on top. If the area holds water after Charleston's heavier rains, a layer of drainage gravel under the fill can help before you build up. None of this is required, but it is how most local jobs actually get finished.

Mulch Mound Pro Tip

Fill dirt has to go down in 6 to 8 inch lifts, each one compacted before the next goes on, or you will be watching your yard settle unevenly for years. This matters more in Charleston than in drier climates, since sandy loam plus heavy seasonal rain can wash out loose, uncompacted fill fast. Rent a plate compactor for anything beyond a small patch job, it is worth the half day rental.

Mulch Mound Pro Tip

The most common mistake we see is people trying to grow grass or plants straight into fill dirt. It is subsoil, stripped of the organic matter and structure that plants need, so it will not support healthy root growth on its own. Always cap fill with 4 to 6 inches of actual topsoil once your grade is set and compacted, then seed or plant into that layer instead.

Mulch Mound Pro Tip

If you are filling a large low spot or backfilling a long foundation run, order fill dirt for the bulk of the depth and save topsoil for just the top few inches. Fill dirt costs less per yard than topsoil since it is not screened for growing quality, so this split gets your grade right without paying premium material prices for structural volume you will bury anyway.

Grading and Filling in Charleston

Charleston sits low, about 20 feet of elevation, and a lot of lots here have soft spots or old fill that settles unevenly over sandy loam. Fill dirt is what people use to bring a yard up to grade before pool decks, sheds, or new topsoil go in, and it is common around here to raise beds away from standing water after heavy rain. Because the native soil already drains fast, structural fill placed and compacted correctly stays put better than it would in heavier clay. This is not a growing medium, it is the base you build on before anything green goes on top.

What Clean Fill Is

Clean fill is screened subsoil free of debris, roots, and contaminants. It is made for volume and grade, and it compacts predictably, which is exactly what you want under slabs, in trenches, and behind walls.

Fill Dirt vs Topsoil

Fill dirt builds the shape of the ground, topsoil grows things on top of it. Bring the grade up with fill, then cap it with 4 to 6 inches of topsoil anywhere grass or plants are going in.

Compact in Lifts

Place fill in layers of 4 to 6 inches and compact each one before adding the next. Dumping the full depth at once leaves voids that settle later, and settling is the one problem fill is supposed to solve.

Frequently Asked Questions

Click a question to see the answer

Answer

What exactly is fill dirt and can I grow grass in it?

Fill dirt is subsoil pulled from excavation sites and screened of rocks and debris. It is a structural material for raising grade and backfilling, not a growing medium, so grass and plants will struggle in it directly. Cap it with 4 to 6 inches of topsoil once it is compacted if you plan to plant or seed over the area.

Answer

How many cubic yards of fill dirt do I need for my yard?

One cubic yard covers about 54 square feet at a 6 inch depth. Measure your square footage, decide your target depth between 6 and 12 inches, and scale from there. A 300 square foot low spot filled 6 inches deep runs close to 5 or 6 cubic yards.

Answer

Do I need to compact fill dirt in Charleston's soil?

Yes, always. Place it in 6 to 8 inch lifts and compact each one before adding the next, especially given how much rain this area sees seasonally. Skipping compaction means the ground keeps settling unevenly for years, which shows up as dips, cracks near foundations, or a pool deck that pulls away from the coping.

Answer

Where will the delivery truck put the fill dirt?

The truck places the load as close to your work area as driveway or curb access allows, and delivery is scheduled at checkout rather than a fixed window. Clear space beforehand for the drop and let us know ahead of time if your access is tight, narrow, or has low branches.

Answer

Should I get fill dirt or topsoil for my project?

Use fill dirt for the bulk of any grading, backfill, or low spot job where nothing needs to grow yet, since it is denser and cheaper per yard. Use topsoil only for the top few inches where you actually plan to plant or seed. Most jobs in Charleston use both, fill for structure and topsoil as the finish layer.
