Concrete Driveways in Colorado Springs, CO

Quick answer

A durable concrete driveway in Colorado Springs starts with careful subgrade work on the region's expansive clay, a compacted aggregate base, an air-entrained mix for freeze-thaw, a slab commonly about four inches thick (thicker for trucks and RVs) and planned joints. The apron at the street usually needs a city right-of-way permit or a county access permit.

A driveway in Colorado Springs takes a beating that slabs in milder places never see. Snow gets shoveled or plowed onto it, melts in the afternoon sun and refreezes overnight. Deicing chemicals ride in on tires. Underneath, much of the region sits on clay that swells when it gets wet and shrinks when it dries. A driveway built for those conditions can last for decades; one poured on a thin base with too few joints can heave, crack or flake within a few winters.

How a durable driveway is built here

  1. Tear-out and excavation. Old concrete or asphalt is broken out and hauled away, and the soil is dug down to make room for a base.
  2. Subgrade work. Soft or organic soil is removed and the subgrade is compacted. On expansive clay, some contractors also talk about moisture conditioning or replacing part of the clay with non-expansive fill. Ask what your contractor recommends for your lot and why.
  3. Base. A compacted layer of crushed aggregate gives the slab even support and helps water drain.
  4. Forms and slope. The driveway should shed water and snowmelt away from the garage and foundation, not toward them.
  5. Reinforcement. Rebar, welded wire or fiber can be used. Reinforcement holds cracks tight; it doesn't stop concrete from cracking.
  6. Placing, finishing and joints. Control joints are tooled or saw-cut at planned spacing, and isolation joints separate the driveway from the garage slab, walks and the street.
  7. Curing. The surface is protected and kept from drying out too fast during the first days.

Built for freeze-thaw

Exterior concrete along the Front Range goes through many freeze-thaw cycles each winter. Air-entrained concrete, which contains tiny, evenly spaced air bubbles, gives freezing water room to expand and is the standard defense recommended by the Portland Cement Association and the American Concrete Institute. Finishing matters too: troweling water back into the surface or finishing while bleed water is present weakens the top layer, and that's often where flaking starts. A plain broom finish also gives better traction on icy mornings than a smooth one.

Thickness and heavy vehicles

Residential driveways are commonly poured about four inches thick, with five inches or more often recommended where trucks, trailers or RVs will park. Many homes on larger lots east of Colorado Springs add RV pads or extra parking; tell the contractor what will sit on the slab so it can be designed for that load.

The apron and the right-of-way

The part of the driveway that meets the street usually sits in the public right-of-way, and the rules depend on where you live. Inside Colorado Springs, the city requires a concrete permit for work in the right-of-way, says only contractors licensed for right-of-way concrete work may do it, and reviews new driveway curb cuts through City Engineering and Traffic. In unincorporated El Paso County, the county requires an Access Permit to build, rebuild, pave or widen a driveway that meets a county road, or to replace its culvert. Fountain, Monument, Manitou Springs and Woodland Park have their own public works offices, so check with your town or city before work starts.

After the pour

  • Keep cars off until your contractor says it's ready, commonly about a week, and heavier vehicles longer.
  • Skip deicers on new concrete during its first winter, and avoid products containing ammonium nitrate or ammonium sulfate entirely.
  • Use a plastic shovel blade if you can, and don't chip ice off the surface with a metal tool.
  • Keep downspouts and sprinklers from soaking the soil along the edges.
  • Ask about a penetrating sealer and when to apply it.

Questions to ask

  • How will you prepare the subgrade on my soil, and what base depth is included?
  • Is the mix air-entrained, and what slab thickness will you use?
  • Where will control and isolation joints go?
  • Who handles the right-of-way or access permit, tear-out and disposal?
  • What does the warranty cover, and can you provide a certificate of insurance?

Frequently asked questions

Do I need a permit to replace my driveway in Colorado Springs?

Work in the public right-of-way, such as the apron, curb cut and sidewalk crossing, needs a city concrete permit, and the contractor must hold the city's license for right-of-way concrete work. New curb cuts are reviewed by City Engineering and Traffic. Ask your contractor who pulls the permit.

What about driveways in unincorporated El Paso County, like Falcon?

El Paso County requires an Access Permit to build, rebuild, pave or widen a driveway that meets a county road, or to replace its culvert. The county also says a paved driveway shouldn't be extended across the right-of-way onto a gravel road. Check with El Paso County Public Works before work starts.

Why is my driveway flaking after a few winters?

Surface scaling usually comes from freeze-thaw damage made worse by deicers, often on concrete that wasn't air-entrained, was finished with extra water, or wasn't cured well. Avoid deicers on new concrete and ask any contractor about mix, finishing and curing before you hire.
