About this fill dirt

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.

Wonderful experience! They put the mulch exactly where we wanted. This mulch spread very easily and didn’t have the usual “mulch smell.” We will definitely use again!

One cubic yard covers about 54 square feet at a 6 inch depth, which is the shallow end of the typical 6 to 12 inch install range for fill dirt. For a job like raising a 200 square foot low spot near Lake Merritt to 6 inches, figure around 3.7 cubic yards, and double that if you're going closer to 12 inches. Measure the actual low area, not the whole yard, since fill is usually targeted rather than spread everywhere.

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 few inches of topsoil capping the fill once it's compacted, especially if lawn or planting beds are going back in. If you're backfilling around a pool or foundation, a layer of gravel or crushed rock at the base can help with drainage before the fill goes in. Mulch shows up later, once the topsoil and plantings are settled.

Mulch Mound Pro Tip

Place fill dirt in 6 to 8 inch lifts and compact each one before adding the next, rather than dumping the full depth at once. Oakland's clay loam already holds water and settles unevenly, so an uncompacted fill layer will keep sinking for a year or two, especially after the winter rains between December and February. A plate compactor rented for an afternoon saves you from redoing the grade later.

Mulch Mound Pro Tip

The most common mistake with fill dirt is treating it like topsoil and planting straight into it. It has no nutrient value and compacts hard, which is exactly what you want for a stable base but not for roots. Always cap with 4 to 6 inches of real topsoil before seeding lawn or setting in plants, otherwise everything struggles no matter how much fertilizer you add.

Mulch Mound Pro Tip

Order fill dirt to match your actual grading need rather than rounding up heavily, since at 1.3 tons per cubic yard, extra material means extra weight sitting in your yard or driveway. If you're both raising grade and topping with topsoil, order them as separate deliveries timed a few days apart so you're not compacting fill and spreading topsoil on the same day.

Grading and Filling in Oakland

Oakland sits on clay loam that already drains slowly, so a lot of fill jobs here are about correcting low spots that pond water after winter rain between December and February. This fill dirt is a structural subsoil, not a growing medium, which is exactly what you want when you are raising grade or backfilling against a foundation near the flats. Because Oakland's clay loam compacts unevenly on its own, this screened fill gives you a more predictable base to build on. If the final surface needs to grow anything, plan on capping it with actual topsoil.

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.

Frequently Asked Questions

Click a question to see the answer

Answer

Is fill dirt the same thing as topsoil for my yard in Oakland?

No, fill dirt is subsoil meant for structural jobs like raising grade or backfilling, not for growing anything. It has none of the organic matter topsoil has. If you're leveling a low spot and want grass or plants on top, you'll need fill dirt to build up the grade and then a topsoil cap on top of that.

Answer

How many cubic yards of fill dirt do I need to raise a low corner of my yard?

One cubic yard covers about 54 square feet at 6 inches deep. Measure the square footage of the low area, decide how many inches you're raising it, and scale from there. A 300 square foot spot raised 6 inches needs roughly 5.5 cubic yards, more if you're going deeper toward the 12 inch end of typical fill depths.

Answer

Do I need to compact fill dirt myself after delivery?

Yes, compaction is on you and it matters. Spread the fill in 6 to 8 inch lifts and compact each layer, especially in Oakland's clay loam, which already settles unevenly on its own. Skipping compaction means the ground keeps sinking for months or years, which is a bigger headache than renting a compactor for a day.

Answer

Where does the truck put the fill dirt when it delivers?

The load gets dumped at a single accessible spot, usually a driveway or curbside area, since fill dirt is heavy and isn't carried into backyards. Clear the drop zone ahead of time and think about how you'll move it from there to a backyard job, whether that's wheelbarrows or a rented cart, especially around tighter Oakland lots.

Answer

Should I use fill dirt or a different material for backfilling around my foundation or pool?

Fill dirt is the right call for foundation and pool backfill because it's a structural material meant to be compacted in place, not a growing medium. Gravel or crushed rock is sometimes layered in first for drainage, but the bulk backfill itself should be fill dirt, compacted in lifts as it goes in.
