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.

Fill dirt is sold by the cubic yard, and one yard covers about 54 square feet at a 6 inch depth. Most structural jobs run 6 to 12 inches deep, so a 200 square foot low spot at 8 inches deep runs close to 5 cubic yards. Measure the area you're filling and the depth you need before ordering, since underordering means a second delivery mid-project.

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 yards of topsoil capping the surface, especially if lawn or landscaping goes on top afterward. Some customers also order crushed base material for driveway or patio subgrades that need more drainage than raw fill provides. Pairing materials on one delivery schedule keeps a multi-stage project moving without waiting on separate trucks.

Mulch Mound Pro Tip

Place fill dirt in lifts no deeper than 6 to 8 inches and compact each one before adding the next. Skipping this step is the single biggest cause of sunken patios and cracked walkways two winters later, especially in Columbia Falls where sandy loam subsoil already drains and shifts more than clay-heavy ground. A plate compactor rented for an afternoon costs far less than repouring concrete over settled fill.

Mulch Mound Pro Tip

Fill dirt is not a planting medium and will not hold nutrients or moisture the way topsoil does. If anything is going in on top, grass, shrubs, garden beds, cap the fill with 4 to 6 inches of topsoil before planting. Skipping the cap means whatever you plant struggles from day one, no matter how well the fill itself was compacted.

Mulch Mound Pro Tip

Order fill dirt and topsoil together when a project needs both, since scheduling one delivery day instead of two saves on coordination and keeps your timeline tighter. This matters more here than in flatter towns, given Columbia Falls' elevation and the shorter working window before frost sets in mid September. Getting structural fill done early leaves room to cap and finish before the ground freezes.

Grading and Filling in Columbia Falls

Columbia Falls sits at 3,092 feet with sandy loam soil that drains fast but doesn't hold shape well when you're trying to build up grade. Fill dirt gives you a stable structural base for that kind of work, whether it's leveling a yard that slopes toward Hungry Horse Dam or raising a low corner before a patio pour. Because the native soil here is loose, compaction matters more than usual, lifts that aren't packed down will settle unevenly once frost works through the ground each winter. This isn't a growing medium, so anything planted on top still needs a topsoil cap.

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

Click a question to see the answer

Answer

Is fill dirt the same as topsoil?

No, fill dirt is subsoil screened of debris and meant for structural work like raising grade or backfilling foundations. It does not have the organic content or nutrients topsoil has, so nothing grows well in it directly. If you're planting on top, cap the fill with topsoil once it's compacted to your finished grade.

Answer

How many cubic yards of fill dirt do I need for my yard?

One cubic yard covers about 54 square feet at a 6 inch depth, so measure your area and multiply by the depth you need in feet, then divide by 27 to get cubic yards. A 300 square foot low spot filled 8 inches deep needs roughly 7.5 cubic yards. Round up slightly since compaction settles the material once packed.

Answer

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

Fill dirt is project driven, not seasonal, so timing depends on your job rather than the calendar. That said, getting structural fill placed and compacted before the ground freezes around mid September gives you more working days and avoids trying to compact partially frozen soil. Spring after the last frost in April also works well once the ground has thawed and dried out.

Answer

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

The load gets dumped in one pile at a spot you mark ahead of time, so have a clear path wide enough for a delivery truck and a flat area near where you'll be spreading the material. Steep driveways or tight access can limit exactly where the truck can reach, so let us know about any access issues when you schedule.

Answer

Should I use fill dirt or crushed gravel for my project?

Fill dirt works for raising grade, backfilling foundations, or building up ground before topsoil goes down, but it holds less structural weight and drains slower than crushed gravel. If you're building a base for a driveway or patio that needs strong drainage, gravel is usually the better structural layer. For general grading and leveling work, fill dirt is the more economical choice.
