What is the difference between topsoil and fill dirt?

Topsoil is screened and holds organic matter, so it supports plant growth. Fill dirt is the structural material underneath. Use fill dirt to raise grade or backfill a foundation, then top it with topsoil for a lawn or bed. In the alkaline soils common here, amending the topsoil layer is often the difference between a lawn that thrives and one that struggles.

What is Class 6 road base and what is it used for in El Paso County?

It is the standard base for driveways, parking pads, and shed or garage floors across the Front Range. It compacts to a firm, stable surface that handles vehicle weight and resists rutting. For heavier traffic, Class 5 is the structural grade, but Class 6 covers most residential and light commercial jobs.

How deep should a gravel driveway base be in El Paso County?

For passenger vehicles, plan on a minimum depth of 4 inches of compacted Class 6 road base. For trucks or equipment, go to 6 inches or more. Because expansive bentonite clay is common here and moves with moisture, the base depth matters more than in stable soils. A drainage layer underneath helps prevent heaving and keeps the drive level through freeze-thaw cycles.

El Paso County, CO Aggregate and Rock Delivery

You are planning a gravel, stone and aggregate delivery in El Paso County, CO, and the first call is often for Class 6 road base. Colorado Rock Supply delivers it, along with the sand, topsoil and decorative stone your job needs.

The ground here moves. Expansive bentonite clay is common along the Front Range and shifts with moisture, so base depth and drainage matter more here than they do in stable soils. Get those two things right and the rest of the job goes fast.

Materials Delivered in El Paso County

Most jobs start with the base. Here is what we deliver and what it is for.

Class 6 road base is the workhorse. Class 5 is the heavier structural grade. We stock Class 6 for the jobs that come up most: a new drive, a pad for a shed or garage, or a base under pavers. It compacts to a firm, stable surface that will hold up under daily use.

Ground Conditions Across El Paso County

Water drives the ground here. Spring snowmelt and short, intense summer thunderstorms put a lot of water on the surface fast. Expansive bentonite clay is common along the Front Range and moves with moisture, so base depth and drainage matter more than in stable soils.

That means a drainage layer under the base is often the difference between a drive that lasts and one that heaves. Runoff on slopes and in drainage swales after snowmelt and monsoon-season storms can scour the soil. Rip rap and cobble are used to armor the bank and slow the water.

Repeated freeze-thaw cycling, often several cycles in a single week at altitude, works against shallow bases. Frost depth runs about 30 to 36 inches in much of the state. Keep the base deep enough and the drainage clear, and the freeze-thaw cycle has less to grab onto.

Base and drainage work runs best from late spring through fall. Frozen ground and snowpack limit compaction in winter at altitude, so plan big jobs for the working season.
