Gravel, Stone and Soil for San Juan County, CO

Gravel, Stone and Soil for San Juan County, CO

You need gravel, stone and aggregate delivery in San Juan County, CO, and Colorado Rock Supply has it. Most jobs around Silverton start with a base of Class 6 road base, the local standard for driveways and pads. Spring snowmelt and short, intense summer thunderstorms shape how you build, so the right base depth and drainage matter more than in stable soils.

Materials Delivered in San Juan County

Class 6 road base is the workhorse here. In Colorado, and Class 6 is the common choice for driveways, parking pads, and shed or garage bases. It compacts well and holds up under repeated freeze-thaw cycling.

For surfacing, driveway gravel tops a compacted base, while walkway gravel gives a finer, walkable path. Crusher fines, also called breeze or pathway fines, are the standard surface for trails and garden paths. Squeegee, or 1/4 inch minus washed sand, is what you want for paver and flagstone bedding.

For drainage behind retaining walls or in downspout runs, drain rock is the reliable pick. For dry creek beds and xeriscape, cobble slows runoff on slopes, and river rock works as decorative ground cover.

Ground Conditions Across San Juan County

Expansive bentonite clay is common along the Front Range and moves with moisture, so base depth and drainage matter more than in stable soils. You need a thicker base to resist that movement. Spring snowmelt and short, intense summer thunderstorms are the main water drivers, and runoff moves fast on slopes and in drainage swales.

After snowmelt and monsoon-season storms, rip rap and cobble are used to armor banks and slow the water. Repeated freeze-thaw cycling, often several cycles in a single week at altitude, means frost depth runs about 30 to 36 inches in much of the state. Base and drainage work runs best from late spring through fall; frozen ground and snowpack limit compaction in winter at altitude.

Frequently Asked Questions

Common questions about gravel and aggregate delivery in San Juan County

What is the difference between topsoil and fill dirt?

Topsoil is screened and made for growing things, so it works for lawn and bed prep. Fill dirt is structural, used for raising grade or backfill before a base goes down. Use fill dirt to build up an area, then add screened topsoil where you plant.

What is Class 6 road base and what is it used for in San Juan County?

In San Juan County, it is the common base for driveways, parking pads, and shed or garage bases. It compacts into a firm layer that holds up under freeze-thaw cycling and the weight of trucks or equipment.

How deep should a gravel driveway base be in San Juan County?

In San Juan County, plan for at least 4 to 6 inches of compacted Class 6 road base. The expansive clay soils and freeze-thaw cycles here demand a thicker base than stable, sandy ground. Add a surface layer of driveway gravel on top for a drivable finish.
