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!

Fill dirt is sold by the cubic yard, and one yard covers about 54 square feet at a 6 inch depth. Most fill jobs run 6 to 12 inches deep depending on how much grade you need to correct, so a 200 square foot low spot at 6 inches runs roughly 4 cubic yards. Measure the area you are raising and the depth needed, then work backward from the 54 square foot per yard figure at 6 inches.

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 once the grade is where it needs to be, especially if lawn, beds, or anything else is going in on top. Some Santa Barbara properties also pair fill with drain rock near foundations or low walls where water needs somewhere to go instead of pooling in the new grade. If you are building up before hardscape or a shed pad, a compactable base layer on top of the fill is worth planning for.

Mulch Mound Pro Tip

Sandy loam like most of Santa Barbara has drains well but does not hold a compacted lift the way heavier clay soils do, it can slump at the edges if you dump and walk away. Place fill in 6 to 8 inch lifts and compact each one with a plate compactor before adding the next, especially near foundations or pool decks where settling later means cracked concrete. Skipping this step is the single biggest reason fill jobs fail years down the road.

Mulch Mound Pro Tip

The most common mistake on backfill jobs here is treating fill dirt like it is ready to plant into. It is subsoil, screened of debris but stripped of the organic matter and structure that plants need. Always cap finished fill with a few inches of real topsoil before seeding, sodding, or planting beds, otherwise anything you plant will struggle even if the grade looks perfect.

Mulch Mound Pro Tip

If you are correcting grade across a larger area, it is worth ordering fill and topsoil together rather than as two separate deliveries, since you will need both anyway and can plan truck access for one delivery day instead of two. This also helps you sequence the job correctly, fill and compact first, topsoil and grading second, rather than mixing the two and losing the structural benefit of compacted fill underneath.

Grading and Filling in Santa Barbara

Santa Barbara sits at 49 feet elevation with sandy loam soil that drains fast but shifts and settles more than people expect, especially on the older lots near downtown and the foothill properties above town. Fill dirt is the material that corrects grade problems before drainage or plantings go in, whether that is a low spot pooling water after a winter rain or a foundation that needs backfill. Because the native soil here is sandy and loose, compaction during fill placement matters more than in a clay-heavy area, uncompacted lifts will settle unevenly over the sandy base. This is structural work, not soil improvement, so plan on capping with topsoil separately if anything needs to grow on top.

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 plant directly into fill dirt once it is graded?

No, fill dirt is subsoil meant for structural grading, not growing. It lacks the organic matter and nutrients plants need. Cap it with a few inches of topsoil before seeding, sodding, or planting anything, otherwise you will see poor root growth and struggling plants even on a perfectly graded site.

Answer

How many cubic yards do I need to raise a 300 square foot low spot?

At a 6 inch depth, one cubic yard covers about 54 square feet, so 300 square feet needs roughly 5.5 cubic yards. If you are going a full 12 inches, plan on close to 11 cubic yards. Round up slightly since compaction will settle the fill a bit below your initial placement depth.

Answer

Do I need to compact fill dirt before building on top of it?

Yes, especially in Santa Barbara's sandy loam, which does not hold shape as well as heavier soils under uncompacted fill. Place it in 6 to 8 inch lifts and compact each layer before adding more. Skipping compaction means settling for years, which can crack pads, patios, or foundations built on top.

Answer

Where will the truck place the fill dirt on delivery day?

Wherever you direct at checkout, as long as the spot is accessible to a delivery truck. Have a clear path and drop zone ready ahead of time, away from fences, low branches, or anything a dump pile could damage. Delivery timing is scheduled at checkout rather than a set window we promise in advance.

Answer

What is the difference between fill dirt and topsoil for my project?

Fill dirt is subsoil for structural grading, raising low areas, and backfill, it is not meant to grow anything. Topsoil has the organic matter and structure plants need. Most grading jobs use fill dirt to build up the base and a topsoil cap on top wherever lawn, beds, or plantings are going in.
