Crushed Stone, Sand and Gravel in Chehalis, WA

Washington Rock Supply handles gravel and aggregate delivery in Chehalis, WA, with bulk loads of crushed stone, sand, topsoil and rock. The workhorse here is 5/8 minus, the crushed surfacing top course that packs hard and sheds water on drives, parking pads and shop aprons.

Across the Lower Columbia, Chehalis valley and the Willapa Hills, fine-grained terrace and hill soils hold water instead of shedding it. That shapes what you order, from the base course up.

Materials for Chehalis Projects

Base and driveway surfacing is where most ground work around Chehalis starts, and in Washington that means a minus product with the crusher fines left in. Fines are what let the rock knit together and hold under a tire instead of rolling away.

5/8 Minus, also called CSTC or 5/8 inch minus, is the top course for drives, parking pads, shed and shop slabs. It goes down as the finished surface, not the structure under it.

1 1/4 Minus, the crushed surfacing base course or CSBC, is the structural course. Its larger top size and lower fines content carry load and stay workable on ground that is soft and wet.

Driveway Gravel suits long rural approaches, farm and forest drives, and equipment parking. Washington quarries sell it as a driveway blend alongside the graded surfacing courses.

Where water has to leave rather than sit, order washed stone. Drain Rock, also called 7/8 clean, is washed with no fines, so it keeps its voids in footing and French drains.

3/4" Crushed Stone covers trench backfill, pipe surround and under-slab drainage with the same free-draining behavior.

Sand and soil round out a load. Washed Sand goes into concrete mixes, paver setting beds and pipe bedding, washed so silt does not sit in the mix.

Top Soil is screened and blended for lawn repair and new turf, and Fill Dirt raises grade and backfills over-excavations before a granular course goes down.

For beds and paths, Walkway Gravel packs tight underfoot, and beauty bark, listed as Shredded Mulch, covers planting beds and tree rings. Natural Pea Gravel is rounded and washed, so it stays loose in play areas, dog runs and planting beds.

Ground and Conditions in Chehalis

Winter is the driver here. Rain and snowmelt arrive faster than valley silt can pass them, and the ground that softens across this part of the state softens because it is full of water, not because it froze and thawed.

That changes the order of operations. A pad or drive needs a free-draining course beneath it so water has somewhere to go, which is why drain rock and clean stone sit under slabs and trenches.

A minus course alone on saturated silt will pump and rut.

Exposed unworked soil is limited to two days through the October to April wet season, so grading in the river valleys is planned around winter flood season as much as around rain. Build the granular course while the ground is workable.

Erosion shows up as shallow slides in weathered hill soils after long rain, bank scour and channel movement along the valley rivers, and sediment washing off cleared ground. Riprap and large round rock armor swales, culvert outfalls and bank toes where winter flow would move smaller stone.
