3/8 Clean, Stone and Soil Delivery in Kent, WA

You need gravel and aggregate delivery in Kent, WA, and you want to know what to order for the job in front of you. Washington Rock Supply sells bulk material by the ton or by the yard, delivered across King County.

Start with 5/8 minus, the crushed surfacing top course this market calls CSTC. It packs hard and sheds water instead of soaking it up, which suits driveways, parking pads and shed slabs.

Materials for Kent Projects

Wet ground is the reason washed stone does so much of the work here. A dense till cap sits under much of the Puget Sound lowland, so winter rain reaches that layer and stops.

The water table then sits close to the surface instead of draining away.

The answer is to take water sideways to daylight. Footing drains, French drains and downspout runs all do that, and they need stone with the fines washed out so the voids stay open.

Drain Rock is the washed 7/8 clean size for footing drains, curtain drains and infiltration trenches. Because it carries no fines, it keeps the open space water needs to move.

3/4" Crushed Stone is the washed counterpart to a minus product. It goes into trench backfill, pipe surround, drain fields and under-slab drainage, where compacting is the last thing you want.

Drywells and heavy drainage call for #4 Crushed Stone, the number 4 size.

For the structural course under a drive or slab, order 1 1/4 Minus, also called CSBC. It sits below a 5/8 minus top course and carries load on soft, wet ground.

Where you want a firm walking surface instead of drainage, Walkway Gravel is the 1/4 minus size. It packs down tight underfoot for garden paths and side yards.

You order online and choose your quantity by the ton or by the yard. Each product page has a calculator if you want to size the load before you check out.

Delivery coverage runs across Kent and the rest of King County, including Seattle, Bellevue, Renton, Federal Way and Kirkland. You pick your delivery date at checkout, and a dump truck tips the load on your site in one pile.

Plan the drop before the truck arrives. The pile lands where the truck can reach, so keep the spot clear of parked vehicles, tools and anything you still need to move.

Ground and Conditions in Kent

Timing shapes a Kent order more than anything else. The wet season runs October through April, and exposed soil in western Washington has to be stabilized within two days in that window, against seven days in summer.

That is why base, paving and paver work gets scheduled for the dry months. Winter work means keeping the grade covered and accepting that rain, not frost, is what softens a base here.

The ground below is glacial, laid down by the Vashon ice sheet. Dense till caps the site, hard enough in its lower part that crews call it hardpan, over outwash sand and the silt and clay of the Lawton beds.

Perched water is the practical result. Rain soaks the loose upper soil, hits the till and stops, so a drive that was firm in August can rut in February once the ground is saturated.

Bluff failure follows the same water. Winter rain perching where outwash sand meets clay below is what undercuts cut slopes and fill, and why drainage stone belongs in the plan from the start.

What gravel is best for a driveway in Kent?

It depends on what the drive sits on. On soft or wet ground, place 1 1/4 Minus as the structural course, then top it with 5/8 minus, which packs hard and sheds water.

For a long rural approach, Driveway Gravel is the surfacing blend. Where drainage is the problem, a washed stone like Drain Rock keeps its voids open.
