Gravel and Aggregate Delivery in Port Orchard, WA

Washington Rock Supply delivers gravel and aggregate in Port Orchard, WA, from 5/8 minus for a driveway top course to screened topsoil for a new lawn. The ground here is glacial, a dense till cap over sand, so what you put on top has to shed water instead of trapping it.

Order online by the ton or by the yard, size the load on the product page calculator, and a dump truck tips it on your site.

Materials for Port Orchard Projects

Grading and bed prep start below the surface. Fill dirt raises grade, backfills over-excavations and builds up low spots before a granular course goes down.

Screened topsoil goes on last, for lawn repair, new turf and grading out settlement. Garden soil is a blend of screened soil and compost for raised beds and vegetable plots.

For the structural work, 1 1/4 minus is the base course under a drive, parking area or slab. It carries load and stays workable on soft wet ground.

1 1/4 Minus sits below a 5/8 minus top course.

5/8 minus, also called crushed surfacing top course, is the Washington default surfacing. The fines stay in, so it packs hard and sheds water.

5/8 Minus finishes drives, parking pads and shed slabs.

Washed stone drains instead of compacting. Drain Rock, sold as 7/8 clean, keeps its voids in footing drains and French drains.

3/4" Crushed Stone backfills trenches and surrounds pipe.

Sand and decorative stone round out an order. Washed Sand goes into concrete mixes and paver setting beds.

Mason Sand mixes mortar and stucco. Natural Pea Gravel suits play areas and planting beds, and Washington River Rock lines dry creek beds and splash pads.

Ground and Conditions in Port Orchard

Across the Puget Sound lowland, 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.

That perched water is why drainage matters more than depth on a till site. Water has to be taken sideways to daylight, which is what footing drains and washed drain rock do.

Winter rain perching where outwash sand meets clay below it is what puts coastal and valley bluffs in this part of the state on the landslide maps. The same perched water undercuts cut slopes and fill on a smaller scale.

The wet season runs October through April. Exposed soil has to be stabilized within two days in that window, against seven days in summer, so base, paving and paver work is scheduled for the dry months.

Winters here are mild and wet. The ground seldom freezes deep, so it is saturation rather than frost that softens a base, and a drive that was firm in August can rut in February.
