Materials Delivered in Grand County
Every project starts with the right material. Here is what to order for common jobs around the county, from a new drive to a French drain. Class 6 is the standard driveway and pad base. Class 5 is the heavier structural grade under drives that carry trucks or equipment. Both are listed on our site as Class 6 Road Base.
Ground Conditions Across Grand 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. A thin base on clay will crack and shift as the ground swells and dries. Plan for a deeper base and a proper drainage layer.
Spring snowmelt and short, intense summer thunderstorms drive most of the drainage work here. Runoff on slopes and in drainage swales after snowmelt and monsoon-season storms can scour the bank. Rip rap and cobble are used to armor the bank and slow the water. Place RipRap at culvert outlets and in swales. Use Colorado cobble in dry creek beds to slow runoff.
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 you. Frost depth is about 30 to 36 inches in much of the state. Set your base below that line where it matters, and give the soil a way to drain.
Delivery Across Grand County
Ordering online is simple. Pick the material you need, choose a quantity by the ton or yard, and schedule your delivery. We deliver to Fraser, Granby, Grand Lake, Hot Sulphur Springs, Kremmling, Parshall, Tabernash, and Winter Park.
Before the truck arrives, have the site ready. Know where the material will go, and make sure the access path is clear for a heavy truck. A bulk delivery is dumped in a pile, so plan for enough space to work from that pile with a skid steer or wheelbarrow.
Choosing the Right Material
The best material for your project depends on where you are and what the ground does. Across Colorado, the same job can call for a different base. In Gunnison, High Country clay and a short season mean a deeper, well-drained base. In Hinsdale, High Country slopes and wet soil push you toward a thicker drainage stone. In Huerfano, High Country conditions are similar, and the ground moves with moisture, so a compacted Class 6 base plus drainage is the safe call.
In Grand County, start with Class 6 road base for most driveways and pads. Add drain rock where water collects. Use Natural Pea Gravel for play areas and light bedding. Match the material to the job, and the base will hold.
