Washed Sand for Patios in Monument, OR

Planning a patio, a paver walkway or a shop pad in Monument, OR means starting with the right base, and that is where gravel and aggregate delivery in Monument, OR earns its keep. Oregon Rock Supply sends bulk material out across Grant County.

The base under pavers here is 3/4 minus, the crushed rock graded 3/4 inch down to fines that compacts and locks up. Everything above it is bedding and finish.

Ground and Conditions in Monument

Across the Blue Mountains and Wallowas, the ground runs from old accreted rock and granitic intrusions up through Columbia River Basalt, with ash caps on the forested slopes and alluvial gravel in the valleys.

That mix is why a thin base shows itself fast here. Water moves through the open gravel, then the fines in the soil below hold it, and the surface rocks and dips underfoot within a season.

Snowmelt drives the water. The high ranges take 50 to 80 inches of precipitation a year and feed valleys that see far less, so spring runoff arrives fast and concentrated.

That runoff scours stream banks and culverts and runs off steep forest roads and bare slopes after wildfire. Around a patio or pad, it means the base has to shed water rather than trap it.

The working season is short between snowmelt and the first hard frosts, and frozen ground stops compaction through the winter. Long cold winters bring sustained hard freezing across the range.

Frost depth is set by the county, at 18 inches from 2,500 to 4,000 feet and 24 inches at 4,000 feet and above. That figure is a footing depth, not a target for a gravel base.

Materials for Monument Projects

Bedding is what sits directly under pavers and flatwork, and it decides whether the surface stays flat. Start with 3/4 minus as the compacted base, then bed on top of it.

1/4 Minus, also called quarter minus, is the fines product that beds pavers and flagstone. It also tops a compacted base and fine grades paths.

Washed Sand beds pipe and levels under slabs and flatwork. It is washed so it drains instead of holding water, which matters where meltwater is moving.

3/4 Minus is the standard Oregon base under driveways, parking pads, shop floors and shed bases. Crushed rock graded 3/4 inch down to fines compacts and locks up.

Drain Rock, also called 1 1/2 clean, is washed and open for French drains, curtain drains, footing drains and downspout runs. Water moves through instead of sitting.

3/4" Crushed Stone is angular rock with the fines screened out. It suits drainage trenches, retaining wall backfill and bridging soft wet ground.

Questions About Gravel in Monument

What gravel is best for a driveway in Monument?

On most Oregon drives that means a minus rock that compacts rather than a clean rock that rolls underfoot. 3/4 minus is the crushed rock graded 3/4 inch down to fines, and it locks up as a base and a wearing surface.

Clean stone such as 3/4" Crushed Stone has the fines screened out, so it drains and stays open instead.

How much material will my project need?

Quantities are ordered by the ton or by the yard, and each product page has a calculator to size the load. Work out the area and the depth you want, then let the calculator turn that into a quantity.

For a base under pavers or flatwork, the depth of the compacted layer is what drives the number.
