Riprap and Bulk Aggregates for Post, OR

Oregon Rock Supply brings gravel and aggregate delivery in Post, OR to driveways, pads and drainage work. The base most ground here starts from is 3/4 minus, the crushed rock graded 3/4 inch down to fines that compacts and locks up under a drive or a shop floor.

Post sits in Crook County, where the ground is young basalt with pumice, cinder and ash soils. That shapes what you order: coarse, open stone for slope and water control, and a fines-bearing base for anything that has to carry weight.

Materials for Post Projects

Slope, swale and bank protection starts with coarse stone. Water off hard ground and bare ash moves fast and cuts, so the material at the edge of a draw or a cut slope has to be heavy enough to stay put.

Riprap is the slope protection rock for stream banks, culvert outlets, pond edges and cut slopes. Oregon riprap is specified by class, from Class 50 up to Class 2000, so the class is how the size gets called out on a plan.

Railroad Ballast is coarse angular rock for track beds, heavy hard standing and severe drainage where a large open stone is wanted. #4 Crushed Stone is large open stone for construction entrances, trench bottoms and heavy drainage, and Oregon yards more often sell this size as 1 1/2 clean.

For water that has to move instead of sit, Drain Rock goes in French drains, curtain drains, footing drains, drywells and downspout runs. It is washed and open, so water passes through rather than pooling in the stone.

3/4" Crushed Stone is the same idea in a smaller, angular stone for drainage trenches, retaining wall backfill and bridging soft wet ground. Below that, 3/8" Crushed Stone handles pipe bedding and tight drainage work.

At the fine end, 3/4 Minus is the standard base under driveways, parking pads, shop floors and shed bases. 1/4 Minus, sold as quarter minus, beds pavers and flagstone and tops a compacted base.

Top Soil finishes lawns and beds.

Delivery to Post and the Surrounding Area

Delivery covers Post and the rest of Crook County, including Prineville, Paulina and Powell Butte. You order online, choose a quantity by the ton or by the yard, and pick a delivery date at checkout.

Each product page has a calculator if you need to size a load. A dump truck then tips the material on site in one pile, so the spot you leave open is the spot the load lands.

Ground and Conditions in Post

The working season here is long and dry, running from late spring into autumn and cut short at both ends by hard frost. That is the window for grading, base work and any soil that has to be moved.

Across Central Oregon and the High Lava Plains, precipitation runs about 8 to 12 inches a year. Pumice and fractured basalt drain very fast, so the usual problem is holding moisture for compaction rather than shedding water.

Summer compaction normally needs added water. Wind across bare pumice and ash moves fines, and short intense summer thunderstorms cut channels in dry draws, which is why coarse stone belongs at outlets and on banks.

Winters are cold and clear at this elevation, with wide day-to-night swings and repeated freeze-thaw. Frost depth figures are published by county, and Deschutes County points applicants at the state design criteria hub for the figure at a given site.

Questions About Stone and Delivery in Post

What stone should I use for drainage in Post?

Washed, open stone is what moves water: drain rock for French drains, footing drains and drywells, and 3/4 clean for drainage trenches and retaining wall backfill. Where the ground is soft and wet, 3/4 clean bridges it.

Keep fines out of a drain, because a minus rock compacts and holds water instead of passing it.

What should I have ready when the truck arrives?

Leave the drop spot clear and reachable, with room for a dump truck to tip a full load in one pile. Order by the ton or the yard, and use the calculator on the product page if you need to size the load.

The truck tips the material where it stops, so pick the spot before the delivery date.
