Gravel and Aggregate Delivery in Sedro-Woolley, WA

Washington Rock Supply brings gravel and aggregate delivery in Sedro-Woolley, WA to grading jobs, garden beds and driveways. If you are building up a low spot or prepping a bed, fill dirt and screened topsoil do the heavy lifting before any stone goes down.

Where a drive or pad is going in over that graded ground, 5/8 minus is the surfacing course to finish with. It packs hard because the crusher fines stay in the mix.

Materials for Sedro-Woolley Projects

Grading and bed prep usually start below the finish grade. Fill dirt, which is also called common borrow, raises grade and backfills over-excavations before a granular course goes down.

Order it from Fill Dirt when you are building up low ground.

Once the grade is where you want it, screened topsoil finishes lawns and new turf. Local yards screen and blend it rather than selling native soil straight, and it goes on thin over a firm subgrade.

See Top Soil for lawn repair and grading out settlement.

For raised beds and vegetable gardens, garden blend mixes screened soil with compost. It is not plain topsoil, so it holds moisture and feeds a bed through the season.

Order it from Garden Soil.

Under all of that, the structural work is 1 1/4 minus, the CSBC base course. It carries load on soft wet ground and sits below a 5/8 minus top course.

Order it from 1 1/4 Minus.

Beauty bark covers beds, tree rings and slopes once the soil is in. Order it from Shredded Mulch.

Ground and Conditions in Sedro-Woolley

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

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

That till is why water behaves the way it does here. Rain soaks the loose upper soil, hits the dense layer and stops, so the water table sits close to the surface all winter instead of draining away.

Anything built on till needs that water taken sideways to daylight. Footing drains and washed drain rock do much of that work, which is why Drain Rock belongs on a lot of these jobs.

It is washed with no fines, so it keeps its voids.

Perched water also undercuts cut slopes and fill on a smaller scale. Where it meets clay below outwash sand, winter rain is what puts slopes on the landslide maps.

Riprap at a culvert outfall or slope toe is how that gets armoured.

The wet season runs October through April, and exposed soil must be stabilized within two days in that window against seven days in summer. Base, paving and paver work is scheduled for the dry months.

What stone should I use for drainage in Sedro-Woolley?

Drain rock, also called 7/8 clean, is the washed stone for footing drains, French drains and infiltration trenches. It has no fines, so it keeps its voids where perched water sits on till.

For trench backfill and pipe surround, 3/4 clean is the washed counterpart to a minus product because it drains instead of compacting.
