Bulk Material Delivery in Metaline Falls, WA

If you are pricing gravel and aggregate delivery in Metaline Falls, WA, the first question is usually which rock the job actually calls for. Washington Rock Supply sells bulk stone, sand and soil by the ton and delivers it across Pend Oreille County.

Most driveways and pads here start with 5/8 minus, the crushed surfacing top course that packs hard and sheds water. This is glaciated mountain country, with thin stony soil over rock on the ridges.

Materials for Metaline Falls Projects

Slope, swale and streambank work is where coarse stone earns its place in this corner of the state. Spring runoff moves a lot of water in a short window, and bare ground above a ditch or bank sheds soil fast.

Start at the coarse end. Riprap is the stone for shoreline, streambank, culvert outfall and cut-slope protection.

Quarry spalls are the smaller size class below those grades, which suits a swale or ditch that sees hard water but not full bank exposure. RipRap is the order to reach for when a winter storm could carry a smaller stone away.

Large round rock, sold as 2 to 8 inch round, armour swales, bank toes and culvert outfalls. Rounded stone does not lock together, so it belongs where the job is absorbing energy and covering ground rather than building a structural base.

See Large River Rock.

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

It is listed under Railroad Ballast.

Move down in size and the drainage work starts. Drain rock, also called 7/8 clean or washed rock, has no fines left in it, so it keeps its voids where a perched water table sits on till.

That makes it the stone for footing drains, French drains and infiltration trenches, linked at Drain Rock.

Below that, 3/4 clean crushed rock is the washed counterpart to a minus product. It drains instead of compacting, so it suits trench backfill, pipe surround, drain fields and under-slab drainage.

Order it at 3/4" Crushed Stone.

For any drive, pad or slab, the structural course goes in first. 1 1/4 minus, also called crushed surfacing base course or CSBC, carries load and stays workable on soft wet ground, and it sits below a 5/8 minus top course.

It is listed at 1 1/4 Minus.

On top of it, 5/8 minus, also called 5/8 minus crushed rock or CSTC, is the Washington default surfacing course. The crusher fines stay in, so it packs hard and sheds water instead of soaking it up.

See 5/8 Minus.

Finishing materials round out an order. Crusher dust, sold as 3/8 minus or screenings, beds pavers and flagstone and compacts rather than drains.

Washed sand goes into concrete mixes, paver setting beds and pipe bedding, with the silt taken out so it behaves through the wet season. Topsoil screens and blends for lawn repair and grading out settlement, and beauty bark covers planting beds and tree rings.

Ground and Conditions in Metaline Falls

This is the coldest corner of the state, and the working season is short. Base, drive and paver work fits between the spring breakup and the autumn freeze, and the window narrows the higher and further north the site sits.

Most of the year's water arrives as snow and leaves over a few weeks in spring. Valley soils can be saturated while the ground below them is still frozen, so timing a delivery matters as much as the material.

Across the Okanogan Highlands and the northeast corner, gravel valley floors drain quickly while till and lake silt do not. On ground that holds water, a washed stone layer keeps a path for it, and a minus product compacts into a firm surface instead.

Long winters and deep ground frost mean frost heave and soft spring ground govern any unbound base. Frost depth is set by the county or city building department, and it can be deeper at elevation.

Spring runoff also scours ditches, culverts and gravel roads during breakup, and it cuts streambanks in the valley rivers. Eastern Washington's wet weather season for erosion control runs October 1 through June 30.

Questions About Ordering Stone in Metaline Falls

What stone should I use for drainage in Metaline Falls?

Drain rock, also called 7/8 clean or washed rock, is the standard choice for footing drains, French drains and infiltration trenches. It is washed with no fines, so it keeps the voids that let water move.

For trench backfill, pipe surround and under-slab drainage, 3/4 clean crushed rock does the same job in a smaller size. Both drain rather than compact.

What should I have ready when the truck arrives?

Have the drop spot cleared and reachable, with room for a dump truck to get in and out. The load is tipped in one pile, so mark the area you want it left in before the truck shows up.

Firm ground under the truck keeps the delivery on schedule, and a clear path avoids damage to lawns, fences and buried lines.
