Crushed Stone, Sand and Gravel in Fort Collins, CO
Contractors and homeowners both rely on gravel and aggregate delivery in Fort Collins, CO, and Colorado Rock Supply serves each the same way. You order by the ton or yard, and we deliver to your site. For a new drive, most jobs here start with Class 6 road base.
Because expansive clay is common along the Front Range, the depth of that base and how water drains around it matter more than in stable soils. We help you match the material to the ground and the season.
Materials for Fort Collins Projects
Soil work often comes first on a Fort Collins job. New lawns and beds do best when you start with screened topsoil or garden soil, both of which add organic matter to the alkaline, low-organic soils common here. Before you lay any topsoil, you may need structural backfill to raise a low grade or backfill a foundation wall.
Once the grade is set, the base and surface materials go down. The table below shows what local crews specify most often.
For paver work, order squeegee by its Colorado name. It is a washed 1/4 inch minus sand that locks pavers in place without shifting. If you need drainage behind a retaining wall or along a downspout, drain rock keeps water moving away from the structure.
Ground and Conditions in Fort Collins
Water drives most of your material decisions here. Spring snowmelt and short, intense summer thunderstorms send runoff across the surface and down through the soil. Expansive clay, common along the Front Range, swells when wet and shrinks as it dries, which can crack slabs and shift a base if the depth is too thin.
That is why a full 6 inches of compacted Class 6 road base is the default for a drive that carries vehicles. The clay moves under the base, not through it, as long as the base is thick enough and water has a place to go. Pair that base with a drainage layer of drain rock or 3/4 inch crushed stone along the low side of the pad.
Timing matters too. Base and drainage work runs best from late spring through fall. In winter, frozen ground and snowpack limit compaction, so a base laid in January will settle unevenly by spring. Plan your grading and base work for the warmer months, and save decorative topping for later in the season.
Freeze-thaw cycling also takes a toll. Repeated cycles, often several in a single week at altitude, lift and shift surface gravel. A compacted base below the frost depth, about 30 to 36 inches in much of the state, keeps the surface stable through those swings.
Delivery to Fort Collins and the Surrounding Area
Bulk material arrives on a dump truck, and you want the site ready before the driver shows up. Clear the area where the load will drop, and make sure the truck can reach it without backing over soft ground or low-hanging branches. We deliver across Fort Collins and to other parts of Larimer County, including Bellvue, Berthoud, Drake, Estes Park, and Glen Haven.
Order online by choosing the material and the quantity in tons or cubic yards. The calculator on each product page helps you convert the area you are covering into the volume you need. If you are unsure between two sizes, call the number on the site and we will walk through your project with you.
What Should I Order for My Project?
Can I order material by the ton for delivery in Fort Collins?
Yes. Every material on our site, from Class 6 road base to screened topsoil, is available by the ton for delivery in Fort Collins. Use the calculator on the product page to estimate your tonnage, then place the order online. If you are building a base for a driveway, plan for the depth to be at least 6 inches to handle the expansive clay common along the Front Range.
What stone should I use for drainage in Fort Collins?
For most drainage jobs, use drain rock or #57 stone. Both are clean, washed stones that let water pass freely without clogging. Use drain rock behind retaining walls and in French drains. For a larger drainage bed or a construction entrance, #4 crushed stone gives you a bigger, heavier stone that stays put under spring snowmelt and summer thunderstorms.
