Bulk Aggregates for Patios in Humptulips, WA

If you are building a patio, setting pavers or firming up a pad, gravel and aggregate delivery in Humptulips, WA starts with the right bedding. Washington Rock Supply sells bulk material by the ton and by the yard.

For most flatwork here the first name on the list is 5/8 minus.

This corner of Grays Harbor County sits on ground that is thin and stony in places and deep and organic in others. That matters under a patio.

Ground and Conditions in Humptulips

Across the Olympic Peninsula and the Pacific coast, the ground varies sharply over short distances. You can hit thin, stony soil over marine rock, deep organic forest soil, or sand, peat and tidal silt near the bays.

A thin base over that kind of ground fails by pumping. The subgrade holds water, the bedding layer works its way down into the soft spots, and the finished surface settles out of level.

The fix is a base course that carries load without turning to mud, with a drainage layer beneath it where water sits. Volume is the driver on the coast side: the west-facing valleys and shoreline take heavy rain, and saturated ground will not hold a base without somewhere for the water to go.

The reliable dry window here is mid to late summer. The two-day soil stabilization rule for western Washington runs from October 1 through April 30, which is the practical limit on open grade.

Winters stay mild enough that the ground is workable in temperature terms. What stops work is how wet it is, not how cold.

Frost depth is set by the county or city building department.

Materials for Humptulips Projects

Bedding is the layer that decides how a patio looks in three years. It has to compact tight and stay put under the paver.

Here is what each material does.

Base and bedding

5/8 Minus, also called crushed surfacing top course or CSTC, is crushed rock with the fines left in. It packs hard and sheds water instead of soaking it up.

Use it for the top course under a patio, driveway or parking pad.

1 1/4 Minus, or crushed surfacing base course, is the structural course under the bedding. The larger top size and fewer fines carry load and stay workable on soft, wet ground.

Stone Screenings, also called crusher dust or 3/8 minus, is a fine minus product. It compacts tight rather than draining, which makes it the setting bed for pavers and flagstone and the material for filling joints.

Drainage and edges

Drain Rock, or 7/8 clean, is washed with no fines. It keeps its voids, so it works in footing drains, French drains and curtain drains where water sits on till.

3/8" Crushed Stone is a clean, washed stone for permeable paver joints and small drain runs. It drains rather than compacts, so it does not belong under a solid paver.

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