Inorganic subsoil for filling holes, raising low ground, and backfill. Small rocks and bits of stick or root are normal in the mix, this is structural material and not a growing medium. Do not use it to level a lawn surface or fill flower beds, put topsoil over it for anything you want to plant. Place it in lifts and compact as you go.
We had a great experience today. This was our first time using Mulch Mound, and I found the price competitive and the online ordering very easy. We are impressed with the quality of the mulch, too! It is covering well - a great value!

How Much Fill Dirt Do I Need?
One cubic yard of fill dirt covers about 54 square feet at a 6 inch depth, so a 10 by 10 low spot at 6 inches runs close to two yards, and a foundation backfill job can run higher depending on depth. Fill dirt is sold by the cubic yard, and it should go down in 6 to 8 inch lifts with compaction between each, not dumped in one deep pour. Measure the actual low area and target depth first, then work backward from there rather than guessing. Estimate fill dirt with our free topsoil calculator
What is a Yard?
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 jobs finish with a cap of topsoil, usually 4 to 6 inches, once the fill is compacted and graded to the shape you want. If the area is going to see grass or planting, screened topsoil on top gives roots something to actually grow in. Some backfill jobs around pools or foundations also call for gravel underneath for drainage before the fill goes in.
Clay loam like what we have around Winston-Salem does not forgive a rushed fill job. Compact every 6 to 8 inch lift with a plate compactor before adding the next, even if it feels slow. Skipping this step is the number one reason people call us back a year later asking why their yard has a dip again, the ground was never actually stable, it just looked stable on delivery day.
Mulch Mound Pro Tip
Do not cap fill dirt with topsoil and seed the same week if you can help it. Give compacted fill a rain cycle or two to settle first, especially with our clay content, then check for low spots before you put topsoil down. Capping too early just buries the settling problem instead of fixing it, and you will see it resurface by next spring.
Mulch Mound Pro Tip
If you are backfilling around a foundation or pool, order a little gravel alongside your fill dirt for the base layer, it drains better than clay ever will and keeps water from sitting against the structure. Combining the two in one delivery is more efficient than two separate trips, and it solves the drainage problem before it becomes a callback.
Grading and Filling in Winston-Salem
Winston-Salem sits on clay loam that already holds water and compacts slowly on its own, so when you add fill you have to be deliberate about it or you end up with soft spots that sink for years. At 970 feet elevation with rolling terrain around the Twin City, drainage direction matters as much as the fill itself, water needs somewhere to go once you raise the grade. This dirt is a structural material, not something to plant into, it is meant to build the shape of the ground back up before topsoil or sod goes on top. Most calls we get here are foundation backfill, pool surrounds, and low yards that pond every spring.
What Fill Dirt Is
Fill dirt is inorganic subsoil sold for volume and grade, not for growing. Small rocks and bits of stick or root are normal in the mix. 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.

Answer
Can I use fill dirt to level my whole backyard in Winston-Salem?
Yes, fill dirt is exactly what you want for raising low grade across a yard. Just plan to compact it in 6 to 8 inch lifts as you go rather than dumping it all at once, and cap with topsoil if you want grass to grow on top. Our clay loam holds moisture, so proper compaction matters more here than in sandier soil.
Answer
How many cubic yards do I need to backfill around a pool?
It depends on the gap width and depth, but as a reference, one cubic yard covers 54 square feet at 6 inches deep. Measure the perimeter gap, multiply by depth in feet, divide by 27, and round up since compaction will settle the material lower than it looks on delivery.
Answer
When is the best time to bring in fill dirt here?
Fill dirt work is really about the job, not the season, so it can go down anytime the ground is not frozen or saturated. That said, working before our first frost around late October or after last frost in mid April avoids fighting wet clay, which compacts poorly when soaked.
Answer
Will the truck be able to access my property for delivery?
Delivery trucks need a clear path, usually a driveway or street frontage wide enough for a dump truck, and the material gets tipped in one pile at that spot. If your access is tight or on a slope, let us know details at checkout so delivery can be planned accordingly.
Answer
Should I get fill dirt or topsoil for my low spot?
Fill dirt is for bulk raising and structural backfill, it is subsoil, not something to grow in. Topsoil goes on top afterward, usually 4 to 6 inches, once your fill is compacted and graded, so anything planted has real growing medium instead of subsoil.
