Bulk Aggregates for Patios in Copalis Beach, WA

Washington Rock Supply handles gravel and aggregate delivery in Copalis Beach, WA for two kinds of buyers: contractors setting pavers and flatwork, and homeowners rebuilding a path or a parking pad. Much of the work starts with 5/8 minus, the crushed surfacing top course this market orders by name.

Ground along the outer coast runs to sand, peat and tidal silt, so what sits under a patio matters as much as what you see on top.

Ground and Conditions in Copalis Beach

Across the Olympic Peninsula and the Pacific coast, the ground is a mix of thin stony soil, deep organic forest soil, and sand, peat and tidal silt along the shore and the bays. Thin soil over rock or loose sand gives a bedding course little to bear on.

A patio laid on a bed that never had a stable base underneath will rut, shift and hold water at the joints. The surface stone is rarely the problem.

What fails first is the layer beneath it.

The coast and the west-facing valleys take 100 to 170 inches of rain a year. Water arrives faster than ground can pass it, and ground already saturated will not hold a base course without a drainage layer under it.

The reliable dry window runs mid to late summer, with a long wet season either side of it. The two-day soil stabilization rule for western Washington applies from October 1 through April 30, which sets the practical limit on open grade here.

Winters stay mild, so temperature is rarely what stops work on this side of the state. Wet ground is.

Frost depth for footings is set by the county or city building department, and published western Washington figures run 12 to 18 inches.

Materials for Copalis Beach Projects

Bedding under pavers and flatwork is where most of the decision-making sits. The bedding has to compact tight and stay put, while the layers below it have to carry load and move water away.

Stone Screenings, also called crusher dust or 3/8 minus, is the bedding material for paver and flagstone setting beds and joint filling. It is a minus product, so it compacts rather than drains, which is exactly what a setting bed needs.

5/8 Minus is the Washington default surfacing course: crushed rock with the fines left in, so it packs hard and sheds water instead of soaking it up. It works for driveways, parking pads, and shed or shop slabs, and it makes a firm sub-base under a patio.

1 1/4 Minus, the crushed surfacing base course, sits below a 5/8 minus top course. Its larger top size and fewer fines let it carry load and stay workable on soft wet ground.

Drain Rock, or 7/8 clean, is washed with no fines, so it keeps its voids. Use it for footing drains, French drains and infiltration trenches where a perched water table sits on till.

Where a washed, fines-free stone is wanted in small drain runs or permeable paver joints, 3/8" Crushed Stone does that job instead of a minus product.
