Gravel and Aggregate Delivery in Union, WA

Washington Rock Supply handles gravel and aggregate delivery in Union, WA for two kinds of buyers: contractors building drives, pads and slabs, and homeowners patching a rutted lane or topping up a path. Most of that work starts with 5/8 minus, the crushed surfacing top course local crews call CSTC.

Union sits in Mason County, on ground laid down by the Vashon ice sheet. The same dense till that makes a base hold also stops water from draining away, so the material you pick matters as much as the depth you place.

Materials for Union Projects

Base and driveway surfacing is where most Union projects begin, because a drive that ruts in February is usually a base problem, not a top course problem.

5/8 Minus is crushed rock with the fines left in, so it packs hard and sheds water instead of soaking it up. It is the Washington default for driveways, parking pads and shed or shop slabs.

Under that goes 1 1/4 Minus, the crushed surfacing base course, or CSBC. The larger top size and fewer fines let it carry load on soft wet ground where a finer material would pump.

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

Washed stone does the drainage work. Drain Rock is washed with no fines, so it keeps its voids in a footing drain, French drain or infiltration trench.

3/4" Crushed Stone is the washed counterpart to a minus product, used for trench backfill, pipe surround and under-slab drainage.

For finished surfaces, Walkway Gravel is the fine end of the minus range and packs tight underfoot on garden paths and side yards. Stone Screenings beds pavers, flagstone and setting beds.

Mason Sand and Washed Sand cover mortar, stucco, concrete mixes and pipe bedding.

Soil and decorative material round out an order. Top Soil is screened and blended for lawn repair and new turf, Fill Dirt raises grade before a granular course goes down, and Shredded Mulch covers planting beds.

Natural Pea Gravel and Washington River Rock suit play areas, dog runs and dry creek beds.

Ground and Conditions in Union

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

That is why drainage matters more than depth in a wet year. Anything built on till needs the water taken sideways to daylight, which is what footing drains and washed drain rock do.

The lower part of that till is hard enough that crews call it hardpan. Below it sits advance outwash sand, and below that the silt and clay of the Lawton beds.

Winter rain perches where the outwash sand meets the clay, and that perched water undercuts cut slopes and fill on a smaller scale than the bluff failures on the landslide maps.

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, so base, paving and paver work is scheduled for the dry months.

Mild, wet winters mean the ground seldom freezes deep here. It is saturation rather than frost that softens a base, and a drive firm in August can rut in February.
