3/8 Clean and Bulk Aggregates for Gig Harbor, WA

Washington Rock Supply runs gravel and aggregate delivery in Gig Harbor, WA, and the load you need usually starts with 5/8 minus. That is the crushed surfacing top course this market calls CSTC.

Each product page has a calculator, so you can size a load by the ton or the yard before you order.

Gig Harbor sits on the Puget Sound lowland, where a dense till cap stops winter rain and pushes the water table up close to the surface. That is why washed stone does so much of the work on lots here.

The drainage work comes first on most sites in this ground: French drains, footing drains, drywells, curtain drains, and downspout runs that need the water moved sideways to daylight.

Washed stone is what those systems take. Drain Rock, also sold as 7/8 clean, has no fines left in it, so it keeps its voids open and the water keeps moving.

#4 Crushed Stone is the larger washed size for drywells.

For under-slab drainage, pipe surround, and trench backfill, 3/4" Crushed Stone is the washed counterpart to a minus product. It drains instead of compacting.

Fines-free stone also beds permeable pavers and fills their joints. 3/8" Crushed Stone is the washed 3/8 clean size.

Where a surface has to pack hard instead of drain, minus products take over. 5/8 Minus is the default surfacing course for drives, parking pads, and shed slabs.

1 1/4 Minus, the CSBC base course, goes underneath it on soft wet ground.

Sand, soil, and decorative stone round out a job. Washed Sand suits concrete mixes and pipe bedding, Mason Sand beds pavers and takes mortar, and Top Soil repairs lawns.

A dump truck tips your material on site in one pile. Bulk delivery to Gig Harbor covers the city and the rest of Pierce County, including Tacoma, Lakewood, Puyallup, Graham, and University Place.

Think about where the truck can reach before the delivery date arrives. The pile lands where the truck stops, and you move it from there with your own equipment.

Ground and Conditions in Gig Harbor

This is the Puget Sound lowland, and the ground here is glacial. A dense till cap sits over advance outwash sand, with silt and clay below that.

Rain soaks the loose upper soil, hits the till, and stops.

So the water table sits close to the surface all winter instead of draining away. Anything built on till needs that water taken sideways to daylight, which is why footing drains and washed drain rock carry so much of the load here.

The same perched water is what puts the bluffs of this region on the landslide maps, and it undercuts cut slopes and fill on a smaller scale.

The wet season runs October through April. Under the state stormwater manual for western Washington, exposed soil has to be stabilized within two days in that window, against seven days in summer.

Base, paving, and paver work gets scheduled for the dry months.

Winters here are mild and wet, and the ground seldom freezes deep. Saturation softens a base more than frost does, so a drive that was firm in August can rut in February.

Pierce County publishes a 12 inch frost depth in its lowlands, and King County publishes 18 inches. Frost depth is a footing depth set by the building official.

Questions About Gravel in Gig Harbor

Do you deliver 5/8 minus to Gig Harbor, WA?

Yes. Washington Rock Supply delivers bulk 5/8 minus to Gig Harbor and the surrounding part of Pierce County.

You order online, choose your quantity by the ton or the yard, and pick a delivery date at checkout. The 5/8 minus page has a calculator for sizing the load before you order.

What gravel is best for a driveway in Gig Harbor?

It depends on what is under it. On soft, wet ground, 1 1/4 minus goes down first as the structural base course, with 5/8 minus as the top course over it.

That pairing is the Washington standard because the fines left in a minus product let it pack hard and shed water rather than soak it up.
