Buy Fill Dirt in Tacoma, WA

Washington Rock Supply brings gravel and aggregate delivery in Tacoma, WA to two kinds of buyers: contractors building grades and homeowners fixing a yard. Most of that work starts with soil, fill and a compacted base, and 5/8 minus is the surfacing course this side of the state knows by name.

Glacial ground laid down by the Vashon ice sheet sits under much of the Puget Sound lowland, and it shapes what you order.

Materials for Tacoma Projects

Grading and bed prep come first on most sites here, so soil and fill carry a lot of the work. You raise the grade, backfill over an excavation, then cap it with a granular course that holds.

Fill Dirt raises grade and backfills over-excavations before a granular layer goes down. It is the bulk material for building up a low corner of a lot.

Top Soil is screened and blended for lawn repair, new turf and grading out settlement. Spread it where grass has to knit back over disturbed ground.

Garden Soil blends screened soil with compost for raised beds, vegetable gardens and new planting beds. It feeds a bed rather than just filling it.

Once the grade is right, the surfacing courses take over.

For rounded stone, Washington River Rock suits dry creek beds and downspout splash pads, and large round rock armours swales and culvert outfalls. Washed sand and mason sand handle concrete, bedding and mortar work.

Ground and Conditions in Tacoma

Rain is the driver here. It soaks the loose upper soil, reaches the dense till cap, and stops.

The water table then sits close to the surface all winter instead of draining away.

On the Puget Sound lowland, that perched water is why anything built on till needs the water taken sideways to daylight. Footing drains and a washed drain rock like 7/8 clean do that work, because clean stone keeps its voids and lets water move.

Where the outwash sand meets the clay below it, winter rain perching on that boundary is what puts bluffs and cut slopes in this part of the state on the landslide maps. The same perched water undercuts cut slopes and fill on a smaller scale.

Mild, wet winters mean the ground seldom freezes deep, so saturation rather than frost softens a base. A drive that was firm in August can rut in February.

The wet season runs October through April. Under the state stormwater manual for western Washington, exposed soil has to be stabilized within two days in that window against seven days in summer.

Base, paving and paver work is scheduled for the dry months, and winter work needs the grade kept covered.

Questions About Ordering in Tacoma

Can I order material by the ton for delivery in Tacoma?

Yes. Quantities are ordered by the ton or by the yard, and you choose the amount when you order online.

If you are unsure how much a project needs, the calculator on each product page can help you size the load before you check out. A dump truck then tips the material in one pile at your site.

What stone should I use for drainage in Tacoma?

Use a washed, fines-free stone so it keeps its voids. Drain rock, also called 7/8 clean, is the usual choice for footing drains, French drains and infiltration trenches.

Where a larger open stone is wanted for trench backfill or under-slab drainage, 3/4 clean does the same job. Keep minus products out of drainage work, because their fines compact instead of draining.
