Bulk Aggregates for Patios in Washougal, WA

Washington Rock Supply handles gravel and aggregate delivery in Washougal, WA, and the wet season shapes how you plan it. Exposed soil is limited to two days of work between October and April, so a load that lands before the rain saves you a torn-up yard.

Start with 5/8 minus, the crushed surfacing top course this state builds on. It packs hard and sheds water instead of soaking it up.

Ground and Conditions in Washougal

Across the Lower Columbia, Chehalis valley and the Willapa Hills, the fine-grained terrace and hill soils hold water rather than shedding it. Ground here softens because it is full of water, not because it froze and thawed.

Pads and drives need a free-draining course under them.

When a base is too thin, the failure shows up as rutting and pumping at the edges. The surface rock sinks into soft subgrade and the patio above it moves.

The fix is a structural course under the surface course. Use 1 1/4 minus, also called crushed surfacing base course, below a 5/8 minus top.

It has a larger top size and fewer fines, so it carries load and stays workable on soft wet ground.

Winter storms back water up in the valleys, and shallow slides in the weathered hill soils follow long rain. Plan grading around the flood season as much as the rain.

Materials for Washougal Projects

Bedding under pavers and flatwork is where a patio is won or lost. The bedding layer has to compact, not drain, so a minus product is the right family for it.

Stone Screenings, also called crusher dust or 3/8 minus, is the standard setting bed for pavers and flagstone. It compacts rather than drains, which is what a bedding course needs.

5/8 Minus is the Washington default surfacing course for driveways, parking pads and shop slabs. The crusher fines stay in the mix, so it packs hard and sheds water.

3/8" Crushed Stone, or 3/8 clean, is washed and fines-free. Use it for paver joints and permeable setting beds where you want drainage instead of compaction.

Walkway Gravel, also called 1/4 minus or quarter minus, is the fine end of the minus range. It packs down tight underfoot for garden paths and side yards.

Drain Rock, or 7/8 clean, is washed with no fines, so it keeps its voids. That matters where a perched water table sits on till.
