Materials for Cortez Projects
Most Cortez projects start below grade. When you need to raise a building pad or backfill a foundation, structural backfill is the right first layer. Contractors here order it as Class 1 or Class 2 backfill. It compacts into a firm sub-base that supports everything placed above it.
For the top of that pad, Class 6 road base is the default choice. Driveways, parking pads, and shed or garage bases all get a layer of this 3/4 inch minus material. It locks together when compacted, so it carries weight without rutting. Crews across Montezuma County use it for the finished grade under concrete and asphalt.
On the Western Slope, drainage work matters just as much as base work. Spring snowmelt and short, intense summer thunderstorms can overwhelm a poorly drained site. Drain rock and #57 stone both move water quickly through French drains and downspout runs. Use rip rap where runoff needs slowing at culvert outlets and swale ends.
Ground and Conditions in Cortez
Expansive clay is common across much of the state, heaviest along the Front Range, and it moves with moisture. Cortez sits on similar ground. That clay swells when wet and shrinks when dry, so base depth and drainage matter more than in stable soils. A thin base over clay will crack and settle within a season.
Base and drainage work runs best from late spring through fall. Frozen ground and snowpack limit compaction in winter at altitude. Plan your excavation and base installation for the working season so you get proper compaction before the ground freezes.
Repeated freeze-thaw cycling, often several cycles in a single week at altitude, also stresses under-built surfaces. A minimum depth of compacted Class 6 road base keeps moisture from working its way up through the clay. Pair that with good drainage, and your pad will hold its shape through the seasons.
