Gravel and Aggregate Delivery in Fall City, WA

Gravel and aggregate delivery in Fall City, WA serves two kinds of buyers: crews building and regrading, and homeowners fixing a drive, a bed or a low spot. Washington Rock Supply sells bulk material by the ton or yard, ordered online.

The local base material here is 5/8 minus, crushed rock with the fines left in so it packs hard.

Materials for Fall City Projects

Much of the work here starts below the surface. Grading and bed prep come first, and that means fill, soil and a base course before any finish material goes down.

The materials below cover that sequence, plus the decorative and sand products that finish a yard.

Fill, Soil and Bed Prep

Fill Dirt, also called common borrow, raises grade, backfills over-excavations and builds up low spots before a granular course goes down. It is not the same as gravel borrow, which is the granular structural fill.

Top Soil, sold here as screened and blended topsoil, handles lawn repair, new turf and grading out settlement. Local yards screen and blend rather than selling native soil straight.

Garden Soil is a blend of screened soil and compost, made for raised beds and vegetable gardens. Shredded Mulch, or beauty bark, covers planting beds, tree rings and slopes.

Base and Surfacing

1 1/4 Minus, also called CSBC or crushed surfacing base course, is the structural course under a drive, parking area or slab. It goes below a 5/8 minus top course and carries load on soft ground.

5/8 Minus, the CSTC or crushed surfacing top course, is the Washington default surfacing. The fines stay in, so it packs hard and sheds water instead of soaking it up.

Washed Stone, Sand and Decorative

Washed products drain instead of compacting. Drain Rock, or 7/8 clean, keeps its voids in footing drains and French drains.

3/4" Crushed Stone suits trench backfill and under-slab drainage.

Washed Sand goes into concrete mixes and paver setting beds, with the silt taken out. Mason Sand is the mortar, stucco and joint-sweeping sand.

For beds and paths, Natural Pea Gravel is rounded and washed, and Washington River Rock armour dry creek beds and downspout splash pads.

Ground and Conditions in Fall City

Across the Puget Sound lowland, the ground is glacial, laid down by the Vashon ice sheet. A dense till cap sits over advance outwash sand, and below that are the silt and clay of the Lawton beds.

The lower till is hard enough that crews call it hardpan.

That layering drives everything. Rain soaks the loose upper soil, reaches the dense till and stops, so perched water sits close to the surface all winter instead of draining away.

Anything built on till needs the water taken sideways to daylight.

This is why footing drains and washed drain rock do so much of the work here, and why a minus product and a clean product are not interchangeable. Minus compacts into a base.

Clean stone drains.

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

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

Winters here are mild and wet, and the ground seldom freezes deep. Saturation softens a base more than frost does, so a drive that was firm in August can rut in February.

Frost depth is set by the building official, at 18 inches in King County.

Questions About Ordering in Fall City

Can I order material by the ton for delivery in Fall City?

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

Each product page has a calculator to help you size the load, and you select a delivery date at checkout. A dump truck then tips the material in one pile at your site.

Have the drop spot clear before the truck arrives so the pile lands where you want it.

What stone should I use for drainage in Fall City?

Use a washed, fines-free stone. Drain Rock, also called 7/8 clean, is the usual choice for footing drains, French drains and infiltration trenches, because it keeps its voids where perched water sits on till.

For trench backfill and under-slab drainage, 3/4" Crushed Stone works as the washed counterpart to a minus product. A minus material compacts instead of draining, so keep it out of a drain run.
