Buy Fill Dirt in Evans, WA

Washington Rock Supply handles gravel and aggregate delivery in Evans, WA for two kinds of buyers: contractors building drives, pads and slabs, and homeowners fixing a yard one load at a time. Both work the same ground, so both end up weighing the same choices.

5/8 minus is the surfacing course this part of Washington builds on. It is crushed rock with the fines left in, so it packs hard and sheds water instead of soaking it up.

Materials for Evans Projects

Grading and bed prep come first on most lots here, because thin stony soil over bedrock does not hold a level on its own. Fill dirt raises grade and backfills over-excavation before a granular course goes down.

Screened topsoil goes over the top for lawn repair and new turf, and garden soil, a blend of screened soil and compost, fills raised beds and vegetable plots.

Under those beds and lawns, the structural work is different material. 1 1/4 minus, the crushed surfacing base course, is the layer under a drive, parking area or slab.

Its larger top size and fewer fines carry load on soft spring ground.

Above it, 5/8 minus, also called crushed surfacing top course, is the surface you drive on. Both names describe how the material is specified locally, and both are minus products: the fines stay in so the rock compacts and holds.

Where water needs to move instead of sit, the clean products do the work. Drain rock, sold as 7/8 clean, is washed with no fines, so it keeps its voids in a footing drain or French drain.

3/4" Crushed Stone is the washed counterpart for trench backfill and pipe surround. 3/8" Crushed Stone suits paver joints and small drain runs.

Sand and decorative stone round out a load. Washed Sand goes into concrete mixes and paver setting beds.

Mason Sand is for mortar, stucco and plaster. Natural Pea Gravel suits play areas and dog runs, and Washington River Rock fills dry creek beds and planting beds.

Ground and Conditions in Evans

Across the Okanogan Highlands and the northeast corner, most of the year's water arrives as snow and leaves over a few weeks in spring. That runoff saturates valley soils while the ground below them is still frozen.

Gravel valley floors drain quickly; till and lake silt do not.

That timing shapes what you build and when. A drive or slab placed on ground that stays wet through breakup will move, so the base course has to carry load rather than sit on a soft subgrade.

Drain rock and the clean stones give water somewhere to go where a perched water table sits on till.

Spring runoff also scours ditches, culverts and gravel roads during breakup, and bare burned slopes shed soil and rock after a wildfire season. RipRap protects culvert outfalls and cut slopes, and Large River Rock armours swales and ditch lines where a smaller stone would be carried off.

The working season is short. Base, drive and paver work fits between spring breakup and the autumn freeze, and the window is shorter the higher and further north the site.

The region's wet weather season for erosion control runs October 1 through June 30, so exposed ground needs cover before then.

This is the coldest corner of the state, with long winters, deep ground frost and a slow breakup. Frost heave and soft spring ground govern any unbound base.

Frost depth is set by the county or city building department and can be deeper at elevation.

Delivery to Evans and the Surrounding Area

Bulk material arrives by dump truck and is tipped in one pile at the delivery point. Have the drop area clear, reachable by a loaded truck, and free of overhead lines or low branches.

Ground that is soft from breakup can limit where a truck can go, so a firm, dry approach helps.
