Gravel and Aggregate Delivery in College Place, WA

Planning a driveway, a patio base or a drainage run in College Place means picking the right material first. Washington Rock Supply delivers gravel and aggregate in College Place, WA, and most drives and pads here start with 5/8 minus.

That is the crushed rock with the fines left in, so it packs hard and sheds water. The rolling ground of the Palouse and the Blue Mountain foothills is the reason it matters.

Materials for College Place Projects

Grading, lawn repair and bed prep carry a lot of the work around here, so soil and fill sit at the front of the list. From there, base, washed stone, sand and decorative cover the rest.

Soil, Fill and Mulch

Fill Dirt, or common borrow, raises grade and backfills over-excavations. It builds up low spots before a granular course goes down on top.

Top Soil is screened and blended for lawn repair, new turf and grading out settlement. Garden Soil mixes screened soil with compost for raised beds and vegetable plots.

Shredded Mulch is what Washington yards list as beauty bark. It covers planting beds, tree rings and open slopes.

Base and Surfacing

5/8 Minus, the local default surfacing course, tops driveways, parking pads and shed slabs. It packs hard and sheds water instead of soaking it up.

1 1/4 Minus, also called CSBC, is the structural course under a drive or slab. The larger top size carries load and stays workable on soft wet ground.

Driveway Gravel suits long rural drives and equipment parking. Walkway Gravel, a 1/4 minus, packs down tight underfoot for garden paths and side yards.

Washed Stone, Sand and Decorative

Drain Rock, sold as 7/8 clean, keeps its voids in footing and French drains. 3/4" Crushed Stone backfills trenches and surrounds pipe.

Washed Sand goes into concrete mixes, paver setting beds and pipe bedding. Mason Sand mixes mortar and stucco and sweeps into paver joints.

Natural Pea Gravel covers play areas and dog runs, and Washington River Rock armours dry creek beds and downspout splash pads.

Ground and Conditions in College Place

Water that cannot get in is the driver across the Palouse and the Blue Mountain foothills. Loess is fine, deep and easily worked, and it moves easily too.

When the top inch thaws over frozen soil below, rain and snowmelt run across the surface instead of soaking in. Every slope becomes a drainage path, and anything built on one needs its runoff routed before it starts cutting.

That is where the minus and clean split earns its keep. A 5/8 minus top course compacts and holds, while a washed stone like drain rock stays open so water passes through.

Sheet and rill erosion of loess on long slopes is the other pressure, driven by rain falling on frozen ground. Eastern Washington's wet season runs October 1 through June 30, and the worst risk arrives with the thaw, not high summer.

Frost depth is set by the county or city building department, so confirm the local number before you plan footings.
