Bulk Aggregates for Drainage in Gunnison, CO
Spring snowmelt and short, intense summer thunderstorms send a lot of water across Gunnison properties. Colorado Rock Supply handles gravel and aggregate delivery in Gunnison, CO, with the washed stone and drain rock that move that water away from foundations, driveways, and low spots. Start with Class 6 road base for any compacted surface, then add the drainage layer your site needs. Expansive clay moves with moisture, so getting the base depth right matters here.
Materials for Gunnison Projects
Pick drainage stone by size. Coarser stone moves more water, finer stone locks together better underfoot. For a French drain or a drywell, start with drain rock. It is clean, washed, and sized to let water flow fast while keeping soil out of the trench.
For downspout runs and drainage behind retaining walls, 3/4 inch crushed stone does the job. It is also a solid choice for a construction entrance where equipment tracks in and out. Need something smaller for pipe bedding or a final drainage layer? 3/8 inch crushed stone fits tight spaces and still drains well.
Where runoff needs slowing, not just moving, cobble works in dry creek beds and swales. It breaks the force of fast water and holds slope in place. For a compacted surface on top, Class 6 road base is the local standard for driveways and parking pads.
Ground and Conditions in Gunnison
Plan your drainage work from late spring through fall. Frozen ground and snowpack limit compaction in winter at altitude, so a base put down in December will not seat properly. Wait for thaw, then build.
Repeated freeze-thaw cycling, often several cycles in a single week at altitude, shifts the ground under any surface. Frost depth runs about 30 to 36 inches in much of the state. That means your base needs enough depth to stay put when the ground heaves. A shallow layer of stone over expansive clay will rut and settle by spring.
Spring snowmelt and short, intense summer thunderstorms are the two times water tests your drainage. A French drain or drywell installed with washed stone handles both. The clean stone keeps voids open so water keeps moving instead of pooling against a foundation or washing out a driveway edge.
Expansive clay is common across much of the state, heaviest along the Front Range, and it moves with moisture. Base depth and drainage matter more here than in stable soils. Do not skimp on the stone under a compacted surface. More depth now means fewer repairs after a wet year.

What gravel is best for a driveway in Gunnison?
Start with Class 6 road base as the compacted layer. It locks together under weight and handles the freeze-thaw cycles common at altitude. For the surface, driveway gravel tops the base and gives a clean driving surface. If your driveway sits low or drains poorly, add a drain rock layer first to move water away before the base goes down.
