Railroad Ballast and Bulk Aggregates for Oak Harbor, WA

For gravel and aggregate delivery in Oak Harbor, WA, Washington Rock Supply sells bulk material by the ton and tips it at your site. Each product page has a calculator, so you can size the load before you order.

Start with 5/8 minus if you are surfacing a drive, a parking pad or a shed slab. It is crushed rock with the fines left in, so it packs hard and sheds water.

Materials for Oak Harbor Projects

Slope, swale and bank work on this island takes coarse stone. Water moves sideways here all winter, and the stone that holds a bank is the stone that stays put when the flow hits it.

Riprap is the heavy end of that work: shoreline, streambank, culvert outfall and cut-slope protection.

Large round rock, the 2 to 8 inch round, arms swales, ditch lines, bank toes and culvert outfalls. Rounded stone of that size stays where a smaller stone would be carried off.

See Large River Rock.

Railroad ballast is the open-graded rock for rail spurs, yard track and heavy equipment pads. Say railroad ballast in full.

See Railroad Ballast.

Below the coarse grades, the minus and clean split does the rest of the work. Minus means the crusher fines stay in, so the rock compacts and holds.

Clean or washed means the fines are taken out, so it drains.

For bedding pavers, crusher dust, also called 3/8 minus or screenings, compacts instead of draining. Where you want the joint to pass water, use 3/8 clean or 3/4" Crushed Stone, which is washed and fines-free.

A dump truck tips the load in one pile where it can reach on your site. Nothing is placed, spotted or spread, so plan where the pile should sit before the truck arrives.

Ground and Conditions in Oak Harbor

Across the Puget Sound lowland, the ground is glacial: a dense till cap over advance outwash sand, with silt and clay below. Rain soaks the loose upper soil, reaches the till and stops, so perched water sits close to the surface all winter.

That is why footing drains and washed drain rock do so much of the work here. Water has to be taken sideways to daylight rather than left to soak down through a layer it cannot pass.

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.
