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.

Online ordering was really simple and I liked the transparent pricing.

Fill dirt is sold by the cubic yard, and one yard spread at 6 inches covers about 54 square feet, less if you go deeper. Most raise and backfill jobs in Columbia run 6 to 12 inches deep depending on how low the spot is, so measure the low area, decide your target depth, and work backward from there. If you are backfilling against a foundation or pool wall, measure the trench volume directly instead of guessing by square footage.

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.

Complete Your Outdoor Project

Most fill dirt jobs finish with a few inches of topsoil on top so grass or beds actually have something to root into, since fill dirt itself is not a growing medium. If you are building up a low spot near a patio or driveway, a layer of gravel underneath the fill can help with drainage before you cap it off. We deliver topsoil and gravel too, so it is easy to stack materials in one trip.

Mulch Mound Pro Tip

In Columbia's clay soil, fill dirt that looks dry on top can still be saturated a few inches down after our spring rains, and compacting wet fill just traps water and creates soft spots that sink later. Let a fresh load sit a day or two after a rain event before you start compacting, especially heading into the wetter stretch before last frost in late March. Dry enough to crumble in your hand is the test, not dry on the surface.

Mulch Mound Pro Tip

The most common mistake we see on backfill jobs is dumping the whole load in at once and calling it done. Fill dirt needs to go in 6 to 8 inch lifts, each one compacted before the next goes on, or you will be watching that ground settle for a couple years, especially around pool decks and foundation backfill where uneven settling actually causes cracking.

Mulch Mound Pro Tip

If your project needs both raising the grade and something to grow in eventually, order fill dirt and topsoil together rather than in two separate deliveries. It saves a second delivery fee and lets you compact the fill fully before capping with topsoil, which is the order that actually holds up instead of mixing the two together by accident.

Grading and Filling in Columbia

Columbia sits on heavy clay that already drains slow, so a lot of yards here have low corners that puddle every time we get a gully washer off the coast. Fill dirt is how you raise that ground back to grade instead of fighting it every season. It also shows up a lot around foundation and pool backfill work near the State House area and older neighborhoods where houses were built on uneven lots. This is structural material, not something to plant into straight away, it needs topsoil capped on top once it is compacted.

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

Answer

Is fill dirt the same as topsoil I can plant in right away?

No, fill dirt is subsoil meant for structural fill, raising grade, and backfill, not for growing anything directly. It has been screened of debris but stripped of the organic matter that plants need. Cap it with a few inches of topsoil once it is compacted if you plan to seed or plant over it.

Answer

How many cubic yards do I need to fill in a low spot in my yard?

One cubic yard covers about 54 square feet at a 6 inch depth, so a 300 square foot low spot at that depth needs a little over 5 cubic yards. If you are going deeper, closer to 12 inches, cut that coverage in half and order accordingly, plus a little extra for compaction.

Answer

When is the best time to bring in fill dirt in Columbia?

Fill dirt is more about the job than the season, but drier stretches make compaction easier since our clay soil holds water a long time after rain. Late summer and fall, before the first frost around November 10, tend to give you the most workable window. Avoid compacting right after a heavy rain if you can help it.

Answer

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

Our driver places the load as close to your project area as the truck can safely reach, usually a driveway or curbside drop if access is tight. Let us know about gates, low branches, or narrow lots when you schedule, since fill dirt loads are heavy and we want a clear path to place it where you actually need it.

Answer

Should I get fill dirt or topsoil for backfilling around my foundation?

Fill dirt is the right call for foundation backfill since it is a denser structural material meant to be compacted in lifts and hold its shape. Topsoil is looser and meant for growing, it will settle unevenly if used as structural fill. Use fill dirt for the bulk of the backfill and topsoil only for the top few inches if grass needs to grow there.
