What is the difference between crushed stone and Natural Pea Gravel?

Crushed stone is angular with sharp edges. It locks together when compacted, making it stable for bases and driveways. Natural Pea Gravel is round and smooth. It shifts underfoot and does not compact, so it works better for play areas and decorative beds. For a stable surface, choose crushed stone. For a loose, decorative look, Natural Pea Gravel is the choice.

Should I order material by the ton or by the yard?

Both units work, but they measure different things. A ton is a weight. A yard is a volume. Heavier materials, like crushed stone, weigh more per yard. Lighter materials, like mulch, weigh less. Tell us what you are building and we can help you figure out the right amount. Order by whichever unit you prefer, and we will handle the conversion.

Which stone is best for drainage in Adams County?

For most drainage jobs, a clean, washed stone works best. Drain rock and #57 stone are common choices. They have no fines, so water moves through them quickly. For a French drain or downspout run, use drain rock. For larger drainage areas or concrete aggregate, #57 stone is a solid pick. The key is a washed stone with consistent size.

Adams County Class 6 Road Base and Gravel Delivery, CO

Colorado Rock Supply provides gravel, stone and aggregate delivery in Adams County, CO. We bring bulk materials right to your site, from Aurora to Brighton and everywhere between.

For most projects, Class 6 road base is the starting point. It is the default base material on the Front Range. Contractors order it for driveways, parking pads, and shed or garage bases.

Materials Delivered in Adams County

We deliver a full line of bulk materials. Each one has a specific job. Here are the most common orders we place in Adams County.

Class 6 road base gets the most attention. It is a crushed aggregate with fines that lock together when compacted. Class 5 is the heavier structural grade, used where trucks or heavy equipment will drive.

Ground Conditions Across Adams County

The ground here shapes every project. Expansive bentonite clay is common along the Front Range. It moves with moisture, swelling when wet and shrinking when dry. This means base depth and drainage matter more than they do in stable soils.

Water is the main force to plan for. Spring snowmelt and short, intense summer thunderstorms put a lot of water on the ground quickly. Runoff on slopes and in drainage swales can scour the soil. Rip rap and cobble are used to armor the bank and slow the water.

Timing matters too. Base and drainage work runs best from late spring through fall. Frozen ground and snowpack limit compaction in winter at altitude. We also see repeated freeze-thaw cycling, often several cycles in a single week. Frost depth runs about 30 to 36 inches in much of the state. A proper base depth and good drainage handle this cycling.

Delivery Across Adams County

We deliver to Aurora, Bennett, Brighton, Commerce City, Denver, Dupont, Eastlake, Henderson, Strasburg, Thornton, and Westminster. Ordering is simple. You pick your material online, choose your quantity, and we bring it to your site.

You can order by the ton or by the yard. The right unit depends on the material and your project. For a base layer, you need enough depth to handle the ground conditions. For drainage stone, volume matters more than weight.

A bulk delivery involves a truck dropping the material where you need it. Plan for a clear path and a spot for the load. We handle the rest.

Choosing the Right Material

The best material for your project depends on where you are in Colorado. Ground conditions vary a lot across the state.

In Alamosa, in the San Luis Valley, soils are different and often sandier. Base material there may need less depth than on the Front Range. In Arapahoe, also on the Front Range, you face the same bentonite clay and freeze-thaw cycling we see in Adams County. Base depth and drainage are just as critical. In Archuleta, on the Western Slope, heavier soils and different drainage patterns can change your base and stone choices.

For most Adams County projects, Class 6 road base is the right call for a stable base. For drainage, use a clean, washed stone like drain rock or #57 stone. For a walkable path, crusher fines are the local standard.
