3/8 Clean for Patios in Loomis, WA

Washington Rock Supply brings gravel and aggregate delivery in Loomis, WA, and the patio work here starts with what goes under the pavers. Loomis sits in glaciated mountain country, where thin stony soil covers granite and gneiss on the ridges.

You can order 5/8 minus, crusher dust, 3/8 clean and the rest of the range by the ton or yard, then take delivery on site in Okanogan County.

Ground and Conditions in Loomis

Across the Okanogan Highlands and the northeast corner, snowmelt delivers most of the year's water in a few weeks each spring. It saturates valley soils while the ground below them is still frozen.

Gravel valley floors drain that water quickly. Till and lake silt hold it, and a patio bed placed straight on either one shows the same failure: edges that settle, joints that open, and pavers that rock underfoot.

Okanogan County building officials set frost depth at 24 inches, so frost heave and soft spring ground govern any unbound base here.

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

Spring runoff also scours ditches and culverts during breakup, and bare burned slopes shed soil and rock after wildfire seasons. Erosion control work in eastern Washington runs October 1 through June 30.

Materials for Loomis Projects

Bedding under pavers and flatwork is where the layer you never see decides how the surface behaves. Crusher dust, also called 3/8 minus or screenings, is a minus product, so it compacts rather than drains.

That makes it the material for paver and flagstone bedding, joint filling and setting beds. Order Stone Screenings when you want a bed that locks the surface above it.

3/8 clean is the washed counterpart. It goes into paver joints, permeable paver setting beds and small drain runs where fines-free stone is wanted instead of a minus.

Order 3/8" Crushed Stone for those beds.

Below the bedding, the structural course comes next. 1 1/4 minus, or CSBC, carries load and stays workable on soft wet ground, placed under a 5/8 minus top course.

See 1 1/4 Minus.

5/8 minus, also called crushed surfacing top course or CSTC, is the Washington default surfacing: crushed rock with the fines left in, so it packs hard and sheds water. Order 5/8 Minus for driveways, parking pads, and shed or shop slabs.

Around the edges of flatwork, drainage does its own job. Drain rock, or 7/8 clean, is washed with no fines, so it keeps its voids where perched water sits on till.

Order Drain Rock for footing drains and infiltration trenches.
