Washed Sand for Patios in Foster, OR

If you are setting a patio, laying pavers, or pouring a slab, gravel and aggregate delivery in Foster, OR starts with what goes under the finish. Oregon Rock Supply sells bulk material by the ton or the yard, delivered to your site.

The ground here is deep valley silt that holds winter rain, so the base course does the work. That means 3/4 minus for the compacted layer, with a finer bedding material on top.

Ground and Conditions in Foster

Across the Willamette Valley and Portland Basin, 35 to 45 inches of rain falls almost entirely between November and March. It lands on tight silt and clay that sheds water slowly, and the lowlands carry a seasonal high water table.

That is why a thin base shows itself as ruts and soft spots by February. The silt below holds water, the base layer moves, and the pavers above start to shift out of line.

Frost heave is a minor problem next to winter saturation, so the answer is a base that drains and locks up, not a deeper hole. Oregon's frost depth figure of 12 inches applies below about 2,500 feet and is set by the county.

Portland treats October 1 to April 30 as the wet weather season and requires bare ground stabilized within two days, against seven days from May 1 to September 30. Base and paving work concentrates in the dry months for that reason.

Materials for Foster Projects

Bedding under pavers and flatwork is where a patio lives or fails, so start with what sits under the sand. 1/4 Minus, also called quarter minus, is the fines product that beds pavers and flagstone and tops a compacted base.

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

For the sand layer itself, Washed Sand is washed so it drains instead of holding water. It beds pipe, levels under slabs and flatwork, mixes into concrete, and works as arena footing.

Where the ground is soft before you start, Quarry Run is raw rock straight from the pit face. It builds up soft ground and raises grade before a graded base course goes on top.

If water needs to move rather than sit, Drain Rock is washed and open for French drains, footing drains, drywells and downspout runs.

Rounded stone has its own jobs: 3/8" Natural Pea Gravel for paths, play areas and dog runs, and Willamette River Rock for decorative beds and dry creek beds.
