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.

Easy to order, great service, and great product. We enjoy the final look of a very neglected beds we inherited!

One cubic yard of fill dirt covers about 54 square feet at a 6 inch depth, and most jobs here run 6 to 12 inches depending on how much grade needs correcting. Measure the low area in square feet, decide your target depth, and order in cubic yards from there. For backfill around a foundation or pool wall, measure the void itself rather than the surface area.

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.

I recently ordered from mulch mound and was thoroughly impressed with every aspect of the experience. The entire process, from placing the order to delivery was seamless and efficient. The mulch arrived exactly on time, and the quality exceeded my expectations. The color was rich and consistent, and I received more than enough to complete my project with proper coverage and packing.

Customer service was equally outstanding. Communication was clear, and the team was responsive and professional throughout. It’s rare to find a company that delivers both a high-quality product and excellent service, but mulch mound did just that.

Highly recommended, and I wouldn’t hesitate to order from them again.

Most fill dirt jobs get capped with a layer of topsoil once the grade is set, especially if lawn or planting beds go on top. If the finished area needs to drain well against San Francisco's wet winters, a base layer of drain rock under the fill is worth considering before you backfill. Mulch comes in later, once the growing layer is placed.

Mulch Mound Pro Tip

San Francisco's clay loam already drains slowly, so if you're filling around a foundation or low yard corner, don't just dump and walk away. Place fill in 6 to 8 inch lifts and compact each one with a plate compactor before adding the next. Skipping this step is the single biggest reason people end up with a sunken patch two years later, especially on the older, uneven lots common around the city's hillside neighborhoods.

Mulch Mound Pro Tip

A common mistake is treating fill dirt like topsoil and planting directly into it. This material is subsoil, screened of debris but stripped of the organic content that plants need. Once your grade is set and compacted, cap it with 4 to 6 inches of actual topsoil before seeding lawn or adding beds. Skipping the cap means slow, patchy growth no matter how much fertilizer gets added later.

Mulch Mound Pro Tip

If you're filling a large low area, it's worth pairing fill dirt with a thin drain rock layer at the base, especially given how much rain the city sees in winter months. This keeps water from pooling against foundations or retaining walls before it can drain through the clay subsoil. It costs a bit more up front but avoids redoing the grading work after the first heavy rain season.

Grading and Filling in San Francisco

San Francisco sits on clay loam over hillsides that were graded and regraded for a century, and a lot of lots have low corners, old foundation gaps, or fill that settled unevenly near retaining walls. Fill dirt is what gets used to correct that before anything gets planted or paved. Because the native soil already holds water and compacts slowly, any fill you bring in needs to be compacted properly in lifts or it will settle right along with the surrounding clay. This is structural material for grading and backfill, not something you plant into directly.

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

Can I use fill dirt to level my backyard in San Francisco?

Yes, fill dirt is the right material for leveling low areas and correcting grade. Given the clay loam common here, make sure to compact it in layers as you go, or the ground will keep settling unevenly for a year or two. If anything needs to grow on top, cap the finished grade with topsoil.

Answer

How many cubic yards of fill dirt do I need for a 200 square foot low spot?

At a 6 inch depth, one cubic yard covers about 54 square feet, so 200 square feet needs roughly 3.7 cubic yards. If you're going deeper, say 12 inches, double that to around 7.5 cubic yards. Order slightly more than the math suggests since compaction will settle the fill lower than it sits loose.

Answer

Do I need to compact fill dirt right away after delivery?

You don't need to compact it the same day, but don't leave loose fill sitting for weeks before building on it, especially through San Francisco's rainy winter stretch when it can get saturated. Place it in 6 to 8 inch lifts and compact each layer as you go rather than piling it all at once and compacting the top.

Answer

Where will the delivery truck place the fill dirt on my property?

The truck places the load wherever you specify at checkout, typically a driveway or curb area closest to where you're working. Make sure that spot is clear and that there's enough overhead and turning room for a delivery truck, since many San Francisco streets and driveways are tighter than they look on paper.

Answer

Should I get fill dirt or topsoil for my project?

It depends on the job. Fill dirt is for raising grade, backfilling, or building up structural base, it is not meant for growing anything. Topsoil goes on top once your grade is set, if you're planting lawn or beds. Most grading projects here use both, fill first, topsoil last.
