3/4 Minus and Bulk Aggregates for Molalla, OR

Looking for gravel and aggregate delivery in Molalla, OR? Oregon Rock Supply delivers bulk material to this part of Clackamas County, and the place to start is 3/4 minus.

It is the dense-graded base that goes under drives, pads and shop floors.

This is wet ground for much of the year, so what you put below the surface matters as much as what shows. Order online and a truck tips the load at your site.

Materials for Molalla Projects

Water is the job here. Drainage work starts with washed stone, the clean material that has had its fines screened out so water moves through it instead of sitting in it.

For French drains, curtain drains and footing drains, drain rock is the washed, open stone that lets water travel. It also handles drywells and downspout runs.

3/4" Crushed Stone, which local yards call 3/4 clean or 3/4 open, is the angular version of the same idea. Use it in drainage trenches, behind retaining walls and where a construction entrance needs to stay firm.

At the smallest end, 3/8" Crushed Stone beds pipe and tight drainage runs. Washed Sand is the washed fine material for pipe bedding and leveling under flatwork.

Where the ground is soft, build it up before you surface it. Quarry Run is raw rock straight from the pit face, used to raise grade on low ground.

3/4 Minus is the graded base that compacts and locks up on top of it.

For beds and paths, 3/8" Natural Pea Gravel is a smooth rounded stone for walkways and dog runs. Willamette River Rock is the larger rounded stone for decorative beds and dry creek beds.

Ground and Conditions in Molalla

Across the Willamette Valley and Portland Basin, 35 to 45 inches of rain falls almost entirely between November and March. That rain lands on tight silt and clay that sheds water slowly.

The working season follows the same pattern. Portland treats October 1 to April 30 as the wet weather season and requires bare ground to be stabilized within two days, against seven days from May 1 to September 30.

Base and paving work concentrates in the dry months.

Plan your delivery around that window. Ground that is soft when the truck arrives stays soft under a drive unless the base handles the water.

Winters here are mild and wet, with only short freezes, so frost heave matters less than saturation and soft subgrade. The frost depth figure of 12 inches is the Oregon number below about 2,500 feet and is set by the county, not by this town.

In the foothills, the soil is red clay and silty clay loam. On the valley floor it is deep silt laid down by ice-age floods, and river gravel runs along the waterways.

That is why a compacting base and a washed drainage layer often go into the same job. One carries the load, the other moves the water away from it.
