Bulk Gravel Delivery to Olga, WA

Planning gravel and aggregate delivery in Olga, WA means working around the wet season, which runs October through April across the Puget Sound lowland. Ground stays saturated longer than it looks.

Washington Rock Supply delivers bulk material by the ton or the yard, and 5/8 minus is the surfacing course most local drives and pads start from.

Ground and Conditions in Olga

Across the Puget Sound lowland, glacial ground sets the terms. A dense till cap sits over sand, and the lower part of that till is hard enough that crews call it hardpan.

Rain soaks the loose upper soil, reaches the till, and stops. The water table then sits close to the surface all winter instead of draining away.

That perched water is the reason a thin base course fails here. It softens from below while the surface still looks intact, so a pad that was firm in August ruts by February.

The fix is to take the water sideways to daylight. A washed, fines-free layer under the structural course gives perched water somewhere to go, and it holds its voids where a minus product would fill them.

Bluff failure follows the same water. Winter rain perches where outwash sand meets clay below it, and the same pressure undercuts cut slopes and fill on a smaller scale.

Timing matters too. Under the state stormwater manual for western Washington, exposed soil in the wet season must be stabilized within two days, against seven in summer.

Base, paving and paver work belongs in the dry months.

Materials for Olga Projects

The material under pavers and flatwork decides how the surface above it behaves. Bedding has to compact without shifting and has to stay level once it does.

Two products cover most of that work, and they are not interchangeable.

Stone Screenings, also called crusher dust or 3/8 minus, is a minus product. The fines stay in, so it compacts rather than drains.

That makes it the setting bed for pavers and flagstone and the material swept into joints. It is the wrong choice where water needs to move.

3/8" Crushed Stone, or 3/8 clean, is the washed counterpart. The fines are taken out, so it drains, which suits permeable paver setting beds, paver joints and short drain runs.

#8 Crushed Stone is the same idea in a numbered size.

Below the bedding, the structural course carries the load. 1 1/4 Minus, or CSBC, has a larger top size and fewer fines than 5/8 minus, so it stays workable on soft wet ground.

5/8 Minus is the Washington default surfacing course, also called crushed surfacing top course, or CSTC. The fines are left in, so it packs hard and sheds water instead of soaking it up.

It caps driveways, parking pads and shed slabs.

Where a run has to drain rather than hold, Drain Rock, or 7/8 clean, is washed with no fines. It keeps its voids in footing drains, French drains and infiltration trenches.

Delivery to Olga and the Surrounding Area

Orders are placed online, and you choose the quantity by the ton or by the yard. If you are unsure how much a pad or path takes, each product page has a calculator you can use before you order.

Sizing the load is the part worth getting right. Undersize it and the work stops; oversize it and you are storing rock you did not need.

A dump truck tips the load in one pile at your site. From there it is your material and your equipment.

Olga sits in San Juan County, and delivery reaches the rest of the county as well, including Friday Harbor, Blakely Island, Eastsound and Lopez Island. You pick a delivery date at checkout.

Questions About Gravel in Olga

What gravel is best for a driveway in Olga?

Use 5/8 minus as the surfacing course. It is the Washington default for drives, with the crusher fines left in so it packs hard and sheds water.

On soft or wet ground, place 1 1/4 minus below it as the structural course. The larger top size and lower fines content carry load where a single course would rut.

How much material will my project need?

Quantities are ordered by the ton or by the yard, and each product page has a calculator you can use to size the load. Have your project measurements ready before you start.

When the numbers are settled, order the quantity online and choose a delivery date at checkout.
