Wilsonville, OR Rock, Gravel and Soil Delivery
Wilsonville is a mid-size city in Clackamas County. Oregon Rock Supply provides bulk materials for raising low areas, backfilling around completed work and building up a stable pad before the next phase of a project. Start with the finished grade, measure the area and account for the depth needed before selecting material.
Wilsonville base rock, fines and drainage material
For a compacted pad or driveway foundation, use 3/4 Minus, also called 3/4 inch minus, dense grade or crushed base. For finish layers, paths and joint fill, 1/4 Minus creates a tighter surface when spread and compacted. Drain Rock keeps open space around drainage work where water needs a route through the stone.
Build up low ground in controlled lifts instead of placing the entire depth at once. Compact each lift before adding the next one, especially under a shed pad, driveway extension or other surface that needs to stay level. A base layer around 4 to 6 inches deep suits many light-use projects, while heavier traffic and soft ground call for a design suited to the load and site conditions.
Clackamas County ground, frost and drainage planning
Oregon's statewide frost-depth guide is 12 inches. Treat that figure as a statewide reference rather than a site-specific requirement, and confirm depth and construction requirements with the local building department before work begins.
From November through April, clay in the Willamette Valley holds water and stays saturated. A driveway placed over wet clay without a draining base can develop ruts by January. Separate the soil from the rock where the project calls for it, establish the intended grade first, then place a draining layer or compacted base suited to the job.
Drain Rock is sold as 3/4 clean and 1 1/2 clean. Use it where water must move through the stone rather than where you need a tightly compacted driving surface. For a firm finished surface, use dense-graded 3/4 Minus below the top layer and compact it in lifts.
