Crusher Dust and Bulk Aggregates for Endicott, WA

Water that cannot get in is the problem on the Palouse. When the top inch of loess thaws over frozen ground, meltwater runs across the surface and every slope turns into a drainage path.

Washington Rock Supply sells gravel and aggregate delivery in Endicott, WA, and the materials that answer that water are washed stone, 5/8 minus and clean rock.

Order by the ton or the yard, then pick your delivery date at checkout.

Materials for Endicott Projects

Start with the washed sizes. Water has to move somewhere, and a fines-free stone keeps its voids open instead of sealing up.

Drain Rock, also called 7/8 clean, is washed rock with no fines. Use it in footing drains, French drains and curtain drains where a perched water table sits on the silt.

3/4" Crushed Stone is the washed counterpart to a minus product, so it drains instead of compacting. Trench backfill, pipe surround and under-slab drainage all take it.

#4 Crushed Stone is the coarse drainage size. Drywells and heavy drain runs take it.

4 as the alternative for gravel backfill for drywells.

3/8" Crushed Stone is a small clean stone for paver joints, permeable paver setting beds and short drain runs where a washed stone is wanted.

Then the minus sizes, which pack instead of drain. 5/8 Minus, the local name for crushed surfacing top course, is crushed rock with the fines left in.

It packs hard and sheds water rather than soaking it up, which suits driveways, parking pads and shed slabs.

1 1/4 Minus is the structural course under a drive, parking area or slab, placed below a 5/8 minus top course. Larger top size and fewer fines, so it carries load on soft wet ground.

For bedding and joints, Stone Screenings, or crusher dust, compact rather than drain. Use it under pavers and flagstone and to fill joints.

Walkway Gravel, also called 1/4 minus, is the fine end of the minus range. It packs down tight underfoot on garden paths and side yards.

Sand, soil and mulch round out an order. Washed Sand goes into concrete mixes and paver setting beds, and Mason Sand into mortar and stucco.

Fill Dirt raises grade and backfills over-excavations before a granular course goes down. Top Soil handles lawn repair and new turf, and Shredded Mulch, or beauty bark, covers planting beds and tree rings.

Ground and Conditions in Endicott

The working season here is long and dry through the summer and closes when the ground freezes. Eastern Washington's wet weather season runs October 1 through June 30, so timing a delivery around the freeze matters more than timing it around the heat.

The worst erosion risk is not high summer, it is the thaw. Warm rain falling on frozen or part-thawed ground is the most damaging condition in this part of the state.

That is why drainage goes in before surfacing. Route runoff away from a slope before it starts cutting, and put clean stone where water collects.

Frost depth is set by the county or city building department. The published figure is 24 inches at Spokane, north of here, and 18 inches in Grant County, so confirm the local number before you plan footings.
