Buy 5/8 Minus in Redmond, WA

Washington Rock Supply handles gravel and aggregate delivery in Redmond, WA, and 5/8 minus is the surfacing course most drives and parking pads here start from. It is crushed rock with the fines left in, so it packs hard and sheds water instead of soaking it up.

Redmond sits on the Puget Sound lowland, where glacial ground leaves a dense till cap under the upper soil. That one fact shapes what you order for a driveway, a pad or a drainage run.

Materials for Redmond Projects

Base and driveway surfacing is where a Redmond project usually begins. The Washington default is 5/8 minus, also called crushed surfacing top course, or CSTC.

It is a minus product: the crusher fines stay in the blend, so it compacts into a firm, water-shedding surface for drives, parking pads and shed slabs. Order it as 5/8 Minus.

Under that top course goes the structural layer. 1 1/4 Minus, also called crushed surfacing base course or CSBC, has a larger top size and fewer fines than 5/8 minus.

It carries load and stays workable on soft, wet ground.

Washed stone does the drainage work. Drain Rock, also called 7/8 clean or washed rock, has no fines, so it keeps its voids open in footing drains, French drains and infiltration trenches.

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

For firm walking surfaces, Walkway Gravel, also called 1/4 minus or quarter minus, packs down tight underfoot on garden paths and side yards. Stone Screenings, or crusher dust, is the bedding and joint-filling material for pavers and flagstone.

Sand and soil round out an order. Washed Sand goes into concrete mixes and paver setting beds, and Top Soil handles lawn repair and grading out settlement.

Rounded stone such as Washington River Rock suits dry creek beds and downspout splash pads.

Ground and Conditions in Redmond

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.

Crews working the lower part of that till know it as hardpan.

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 fines-free stone matters more here than a compacting one.

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.

Base, paving and paver work is 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. It is saturation rather than frost that softens a base, and a drive that was firm in August can rut in February.

Footing depth is set by the building official.
