3/4 Clean, Stone and Soil Delivery in Curtis, WA

Washington Rock Supply handles gravel and aggregate delivery in Curtis, WA, and the ground here decides what goes under a drive or pad. Across the Lower Columbia, Chehalis valley and the Willapa Hills, the fine-grained terrace and hill soils hold water instead of shedding it.

That makes 5/8 minus the usual surfacing choice, because the fines stay in and the rock packs hard. Under it, a washed stone course gives water somewhere to go.

Materials for Curtis Projects

Washed stone does the drainage work on a wet site. With the fines taken out, the voids between the particles stay open, so water moves through instead of sitting against a footing or a slab.

Start with Drain Rock, also sold as 7/8 clean. It suits footing drains, French drains, curtain drains and infiltration trenches, and it holds its voids where a perched water table sits on till.

For trench backfill and pipe surround, 3/4" Crushed Stone is the washed counterpart to a minus product, so it drains rather than compacts. Use it around drain fields and under-slab drainage runs.

Drywells and heavier drainage call for a coarser open stone. #4 Crushed Stone is the size for that work.

4 as the alternative for gravel backfill for drywells.

Downspout runs and small drain lines are where a finer washed stone fits. 3/8" Crushed Stone is washed and fines-free, so it works in permeable paver setting beds and short drain runs.

Once drainage is handled, the surface course goes on. 5/8 Minus is crushed surfacing top course, CSTC, and it is the Washington default for driveways, parking pads and shed or shop slabs.

Below it sits 1 1/4 Minus, or crushed surfacing base course, CSBC. The larger top size and fewer fines let it carry load and stay workable on soft, wet ground.

Delivery to Curtis and the Surrounding Area

Ordering runs through the site. You pick the material, choose a quantity by the ton or by the yard, and set a delivery date at checkout.

Each product page carries a calculator if you want to size the load before you commit.

A dump truck tips the load in one pile at the address you give. That is the whole of it, so plan where you want the pile to land before the truck arrives.

Curtis sits in Lewis County, and delivery covers the surrounding area, including Centralia, Chehalis, Winlock, Morton and Mossyrock. Whether the site is a rural approach or a pad behind a shop, the same online order covers it.

Ground and Conditions in Curtis

The working season shapes the schedule here. Western Washington runs an October to April wet season, and exposed unworked soil is limited to two days on a site.

Grading in the river valleys gets planned around the winter flood season as much as around the rain.

That timing matters because the soil holds water. Fine-grained terrace and hill soils across this part of the state drain slowly, and the Chehalis and lower Cowlitz back up in winter storms.

A pad or drive on ground like that needs a free-draining course beneath it.

Erosion is the other half of the picture. Long rain brings shallow slides in weathered hill soils, and riverbank scour moves channel material.

On cleared ground, sediment washes off the bare surface.

Winters here are mild and wet, with only shallow frost. Ground that softens in Curtis softens because it is full of water, not because it froze and thawed.

So the base depth question is really a drainage question.

Plan the delivery around the weather window you have. If a stretch of dry days is coming, that is the time to get the granular courses down and packed before the next system arrives.
