Crushed Stone, Sand and Gravel in Nooksack, WA

Washington Rock Supply handles gravel and aggregate delivery in Nooksack, WA for two kinds of buyers: contractors working through a build schedule and homeowners fixing a drive, a shed pad or a wet corner of the yard. Both want the same thing from the material.

It has to hold up under a Whatcom County winter.

Start with 5/8 minus. It is crushed rock with the fines left in, so it packs hard and sheds water instead of soaking it up.

That makes it the default surfacing course for drives, parking pads and shop slabs here.

Materials for Nooksack Projects

Base and driveway surfacing carries the weight on most sites, so it is worth getting the layers right before anything else arrives. A structural course goes down first, then a finer course on top.

1 1/4 Minus, which Washington yards also call CSBC or crushed surfacing base course, is the structural layer under a drive, a parking area or a slab. Its larger top size and lower fines content let it carry load and stay workable on soft ground.

Above that goes 5/8 Minus, or CSTC, the crushed surfacing top course. It is the same minus family with a smaller top size, and it finishes tighter underfoot.

For long rural approaches and equipment parking, Driveway Gravel is sold as a blend alongside the graded surfacing courses.

Washed stone does a different job. Fines have been taken out, so the stone keeps its voids and water moves through it.

Drain Rock, also called 7/8 clean, goes into footing drains, French drains and infiltration trenches.

For trench backfill, pipe surround and under-slab drainage, use 3/4" Crushed Stone. It drains instead of compacting.

Paver joints and small drain runs take 3/8" Crushed Stone.

Sand, soil and decorative material round out an order. Washed Sand goes into concrete mixes, paver setting beds and pipe bedding.

Top Soil is screened and blended for lawn repair and new turf.

Rounded stone is filed under round rock in Washington, not crushed. Washington River Rock suits dry creek beds, downspout splash pads and rain garden armour.

Natural Pea Gravel is washed and rounded, so it will not compact and belongs in play areas, dog runs and planting beds.

Ground and Conditions in Nooksack

Across the Puget Sound lowland, the ground was 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 layering drives the drainage problem. Rain soaks the loose upper soil, reaches the dense till and stops.

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

Anything built on till needs the water taken sideways to daylight. That is why footing drains and washed drain rock do so much of the work on this ground, and why a granular base that stays saturated will soften.

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

Winters here are mild and wet, so the ground seldom freezes deep. Saturation, not frost, is what softens a base.

Frost depths in this part of the state run 12 to 18 inches depending on the jurisdiction, and the building official sets footing depth for your project.
