Gravel and Aggregate Delivery in Selah, WA

If you are building a drive, setting a shop slab or bedding a new garden, you need gravel and aggregate delivery in Selah, WA. Washington Rock Supply sells bulk material by the ton or the yard and tips it on your site.

Most surfacing work here starts with 5/8 minus, the crushed rock that packs hard because the fines stay in it. Around the valley, silt ground dries loose and sheds sudden water rather than soaking it up.

Materials for Selah Projects

Grading, lawn repair and bed prep drive a lot of the work on valley lots, so soil and fill lead the list. Screened topsoil and garden soil give you something to plant into, and fill dirt brings a low spot up to grade before a granular course goes over it.

Under any of that, you need a base that carries load. The two minus courses below are the standard pair for drives, parking pads and shed slabs in this part of Washington.

• Top Soil for lawn repair, new turf and grading out settlement. Washington yards screen and blend it rather than selling native soil straight.
• Garden Soil is a blend of screened soil and compost, made for raised beds and vegetable plots.
• Fill Dirt raises grade and backfills over-excavation before a granular course goes down.
• 5/8 Minus, also called crushed surfacing top course or CSTC, is the surfacing course for drives and pads. The fines are left in, so it compacts and sheds water.
• 1 1/4 Minus, or crushed surfacing base course, is the structural course under a 5/8 minus top. Fewer fines and a larger top size let it carry load on soft wet ground.

Ground and Conditions in Selah

Water is the driver here, and it arrives in two very different ways. Across the Columbia Basin, Yakima Valley and the channeled scablands, some ground takes only seven to nine inches of rain a year.

Then a thunderstorm or a fast thaw lands on dry silt that sheds water instead of absorbing it. Where flood gravel sits at the surface, water disappears straight down instead.

That split decides what goes under your project. A compacted minus course holds up where the ground stays dry, and drain rock keeps its voids where water sits on tight ground.

Wind off bare dry silt moves soil, and short violent runoff cuts rills in loess when a cloudburst hits ground with no cover. Irrigation runoff moves soil too.

Cover and grading matter through the long working season.

Winters here are cold and dry, and the ground freezes properly, so frost heave in an unbound base is something to design for. Once snow falls or the ground freezes, placing and compacting base material stops being practical.

Delivery to Selah and the Surrounding Area

Questions About Ordering in Selah

Can I order material by the ton for delivery in Selah?

Yes. Bulk gravel, stone, sand, soil and mulch are ordered by the ton or by the yard, and you choose the quantity when you check out.

Each product page carries a calculator if you want to size the load first. A dump truck then tips the material on your site.

What stone should I use for drainage in Selah?

Drain rock, also called 7/8 clean, is the washed stone for footing drains, French drains and infiltration trenches. Because the fines are washed out, it keeps open voids instead of compacting shut.

For trench backfill and under-slab drainage, 3/4 clean does the same job in a different size.
