Gravel and Aggregate Delivery in Federal Way, WA

Gravel and aggregate delivery in Federal Way, WA runs on the calendar. The wet season here lasts from October through April, and exposed soil has to be stabilized within two days in that window.

That leaves a short stretch for base, paving and paver work.

Washington Rock Supply sells bulk material online for delivery across the city. 5/8 minus, the crushed surfacing top course, is the surfacing most drives and pads in Federal Way start from.

Materials for Federal Way Projects

Base and driveway surfacing carries the load on almost every job here. The material is crushed rock with the fines left in, so it packs hard and sheds water instead of soaking it up.

Start with 5/8 Minus, also called crushed surfacing top course or CSTC. It is the Washington default for driveways, parking pads, and shed and shop slabs.

Under it goes 1 1/4 Minus, or crushed surfacing base course. The larger top size and fewer fines let it carry load and stay workable on soft ground.

Long rural approaches and equipment parking take Driveway Gravel, sold as a blend beside the graded surfacing courses.

Where water has to move instead of sit, use washed stone. Drain Rock, also called 7/8 clean, keeps its voids in footing drains and infiltration trenches.

3/4" Crushed Stone does the same job in trench backfill and under-slab drainage.

For bedding and joints, Stone Screenings (crusher dust) compacts under pavers, while 3/8" Crushed Stone stays open for permeable joints.

Ground and Conditions in Federal Way

Across the Puget Sound lowland, rain soaks the loose upper soil, reaches the dense glacial till and stops. The water table then sits close to the surface all winter instead of draining away.

That perched water is the reason drainage matters more than depth on a lot of sites. A drive that was firm in August can rut in February, because it is saturation rather than frost that softens a base here.

The same water does bigger damage where outwash sand meets clay below it. It perches there, and that is what puts the bluffs of this region on the landslide maps.

On a smaller scale it undercuts cut slopes and fill.

So anything built on till needs the water taken sideways to daylight. That is why footing drains and washed drain rock carry so much of the work in Federal Way.

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