Local ground conditions shape the material choice. Expansive bentonite clay is common along the Front Range and moves with moisture, so base depth and drainage matter more than in stable soils. Getting the right base down the first time saves you from a soft, wavy drive later.

Class 6 road base is the workhorse base material here. It compacts into a firm, stable layer that handles daily traffic and seasonal weather shifts.
For drainage behind retaining walls or around foundations, #57 stone and #67 stone are common washed options. They are also used as concrete aggregate. When you need to armor a slope or slow runoff, rip rap and cobble are the heavy-duty choices.

The main failure mode here is a thin base on expansive clay. That clay moves with moisture, so a base that is too shallow will crack and shift. The fix is a thicker base of Class 6 road base, compacted in lifts, with drainage routed away from the area.
Spring snowmelt and short, intense summer thunderstorms drive most drainage problems. Runoff on slopes and in drainage swales after snowmelt and monsoon-season storms can scour the ground. Rip rap and cobble are used to armor the bank and slow the water before it cuts a gully.
Timing matters for any base or drainage job. Base and drainage work runs best from late spring through fall; frozen ground and snowpack limit compaction in winter at altitude. Repeated freeze-thaw cycling, often several cycles in a single week at altitude, also works against a poorly compacted base. Frost depth runs about 30 to 36 inches in much of the state, so a solid, well-drained base is your best defense.
Delivery Across Montrose County
Ordering from Colorado Rock Supply starts online. You choose your material and then decide how much you need, either by the ton or by the cubic yard. For most base and drainage work, the ton is the simpler measure because it accounts for the weight of the material.
Estimating quantity is straightforward. For a driveway base, plan on 4 to 6 inches of compacted Class 6 after the ground is prepped. We deliver to Bedrock, Montrose, Naturita, Nucla, Olathe, Paradox, and Redvale, along with the rest of the county.
Choosing the Right Material
The right base material shifts across Colorado, depending on the ground you are building on. In Morgan and Otero on the Eastern Plains, the soil is often sandy or silty, so a standard Class 6 base with good drainage is usually enough. The main issue there is keeping the base dry and stable.
Up in Ouray on the Western Slope, the terrain is steeper and the freeze-thaw cycle is more aggressive. That calls for a deeper base and attention to drainage, often with a heavier stone like Class 5 for structural support. For Montrose County, the mix of clay soil and seasonal storms means base depth and drainage are the priorities.
