Bulk Aggregate Delivery Across Morrow County, OR
Oregon Rock Supply delivers gravel, stone and aggregate in Morrow County, OR, and 3/4 minus is the material to start with. It is crushed rock graded 3/4 inch down to fines, so it compacts and locks up under a drive, a parking pad or a shop floor.
Work here runs between hard frost at one end and summer dust at the other. Across the Columbia River Gorge and Plateau, the ground is basalt under wind-laid loess, which turns greasy when wet and sheds water fast when dry.
Materials Delivered in Morrow County
Base rock, washed stone, sand, soil and decorative stone cover most of the ground work here. Use this table to match a material to the job.
3/4 minus is the standard Oregon base. Oregon specifies base material by top size with a minus notation, and the Oregon Standard Specifications for Construction set dense-graded base aggregate at 2 1/2 inch - 0, 2 inch - 0, 1 1/2 inch - 0, 1 inch - 0 and 3/4 inch - 0.
Section 00641.10 states that base aggregate is dense-graded unless otherwise specified.
Open-graded aggregate is the clean, fines-free material, covered in Section 02630.11. That is the difference that matters: minus compacts, clean drains.
Quarry run, also called pit run, is raw rock straight from the pit or quarry face. It builds up soft ground and raises grade before a graded base course goes on top.
Natural Pea Gravel suits paths, play areas, dog runs and drainage where a smooth rounded stone is wanted. Riprap, specified by class from Class 50 up to Class 2000, armors stream banks, culvert outlets, pond edges and cut slopes against winter runoff.
Choosing the Right Material
Gilliam County and Umatilla County both sit on the same ground as Morrow County. Columbia River Basalt flows under wind-laid loess, with deep silt on the wheat ground and shallow soil where the basalt comes near the surface.
The ground is the same, so the material choice is the same. A minus rock that compacts is the base, and a clean open stone is the drainage layer.
Match the material to the job instead of the address. Bedding under pavers takes 1/4 minus.
A trench that has to move water takes drain rock or 3/4 Crushed Stone.
Ground Conditions Across Morrow County
Across the Columbia River Gorge and Plateau, precipitation runs about 8 to 15 inches a year. The trouble is not volume.
It is loess that turns greasy when wet and sheds water fast when dry.
Frozen ground in winter sends runoff instead of soaking it in. That is why slope protection and open drainage matter on the plateau.
On bare loess, wind moves soil. Cultivated slopes cut rills and gullies, and summer thunderstorms send sudden runoff down dry draws.
Water for compaction usually has to be hauled. Plan a base that compacts well with what the ground gives you, and put a clean drainage layer where water needs to leave.
