Fill and Base Material Delivered in Manning, OR

If you are pricing gravel and aggregate delivery in Manning, OR, start by sizing the load. Oregon Rock Supply sells bulk material by the ton or by the yard, and every product page carries a calculator for that.

Most ground work around here starts with 3/4 minus, the crushed rock graded 3/4 inch down to fines that compacts and locks up under a drive, a pad or a shop floor.

Delivery to Manning and the Surrounding Area

You order online, choose your quantity, and pick a delivery date at checkout. A dump truck then tips the load on your site.

We deliver across Washington County, including Hillsboro, Beaverton, Forest Grove, Tualatin and Sherwood. Manning sits in Washington County, so a job here is a standard bulk delivery.

Work out your tonnage before you order, because a short load stalls a pour and a long one leaves a pile sitting on the grade.

Materials for Manning Projects

This is fill and sub-base country. A lot of work around Manning starts with raising grade or building a pad, and that means choosing between raw and processed material before anything gets surfaced.

Fill Dirt is bulk fill for raising grade, backfilling and building up low ground. It goes down first, before a graded base course goes on top.

Quarry Run is raw rock straight from the pit or quarry face, uncrushed and rough. It builds up soft ground and raises grade on a pad site.

3/4 Minus, also called 3/4-0, is the standard Oregon base under driveways, parking pads, shop floors and shed bases. The fines let it compact and lock up.

Driveway Gravel surfaces an existing drive or tops a compacted base. On most Oregon drives that means a minus rock that compacts rather than a clean rock that rolls underfoot.

For drainage rather than fill, Drain Rock is washed and open, so water moves through it instead of sitting in the trench. It suits French drains, footing drains, drywells and downspout runs.

Ground and Conditions in Manning

Across the Willamette Valley and Portland Basin, the valley floor is deep slackwater silt left by the ice-age Missoula floods. In the foothills you get red clay and silty clay loam of the Jory series, and river gravel along the waterways.

That silt and clay sheds water slowly. This part of the state takes 35 to 45 inches of rain a year, almost all of it between November and March, and the lowlands carry a seasonal high water table.

The practical result is a soft subgrade. A pad or drive built on fill that was never brought up properly will move under a truck, no matter what surface goes on top.

Winter is also the hard season for bare ground. Portland treats October 1 to April 30 as the wet weather season, with bare ground to be stabilized within two days, against seven days from May 1 to September 30.

Frost is a minor concern here next to saturation. Washington County sets the frost depth at 12 inches, the Oregon figure below about 2,500 feet, and that is a footing depth rather than a gravel base depth.
