5/8 Minus, Stone and Soil Delivery in Friday Harbor, WA

If you are pricing gravel and aggregate delivery in Friday Harbor, WA, the first question is usually which stone and which size. Washington Rock Supply sells bulk material by the ton or the yard, delivered from the mainland by barge to San Juan County.

For most drives, pads and shop floors here, that means 5/8 minus: crushed rock with the fines left in, so it packs hard and sheds water instead of soaking it up.

Materials for Friday Harbor Projects

Wet ground on this island gets managed with washed stone. Washed stone has had the fines taken out, so water moves through the voids instead of sitting in the rock.

That is the difference between a drain that works in February and one that does not.

Start with Drain Rock, also called 7/8 clean. It goes in footing drains, French drains and curtain drains, and it is the material that carries perched water sideways to daylight.

For a drywell, #4 Crushed Stone is the open-graded size.

Downspout runs and trench work take 3/4" Crushed Stone, the washed counterpart to a minus product.

When the surface has to hold up, the order flips to minus material. 1 1/4 Minus, the crushed surfacing base course, is the structural course under a drive or slab.

5/8 Minus goes over it as the surfacing course.

Finer work has its own sizes. Stone Screenings, or crusher dust, bed pavers and flagstone, while Mason Sand handles mortar, stucco and paver joint sweeping.

Delivery to Friday Harbor and the Surrounding Area

You order online, choose a quantity by the ton or by the yard, and pick a delivery date at checkout. Each product page has a calculator if you want to size the load before you commit.

A dump truck tips the material in one pile at the delivery point. From there it is your site and your equipment, so pick a spot that keeps the pile clear of the work you are doing next.

Friday Harbor sits in San Juan County, and delivery reaches the rest of the islands too: Blakely Island, Eastsound, Lopez Island and Olga. Water crossings mean the truck and the barge schedule have to line up, so a delivery date is worth setting before the work starts.

If your project is on a shoreline or a cut slope, the order often includes armouring stone alongside the surfacing material so both land on the same day.

Ground and Conditions in Friday Harbor

Across the Puget Sound lowland, the working season runs October through April. In that window, exposed soil on a western Washington site has to be stabilized within two days, against seven days in summer.

That changes what you order and when you order it.

Base, paving and paver work gets scheduled for the dry months. Winter work means keeping the grade covered and accepting that a drive firm in August can rut in February.

Saturation, not frost, is what softens a base here.

The ground itself is glacial: a dense till cap, its lower part hard enough that crews call it hardpan, over sand and, below that, silt and clay. Rain soaks the loose upper soil, reaches the till and stops.

The water table then sits close to the surface all winter.

That perched water is why washed stone does so much of the work on this side of the state. A footing drain in drain rock takes the water sideways to daylight, and the same perched water is what undercuts cut slopes and fill on a smaller scale.

Get the drainage layer right and the granular courses above it behave. Skip it and the base stays soft no matter how much rock goes on top.
