Concrete driveways in Boulder
A new or replacement concrete driveway is one of the biggest concrete jobs most homeowners take on, and one of the longest-lasting when it's poured properly. Most replacements include breaking out and hauling away the old slab, regrading and compacting the base, forming, pouring and finishing.

Boulder sees strong chinook winds, spring hail and quick swings between warm days and freezing nights.
Freeze-thaw cycles and spring hail are the main enemies of concrete in Boulder. Air-entrained concrete, good drainage and a sealer help it last.
Anything in the public right-of-way, like a driveway approach or the sidewalk, needs City of Boulder approval. A good contractor will handle the permit.
Common questions
How thick should a driveway be?
Four inches is common for cars; five to six inches is better if you park trucks, trailers or an RV on it.
Should I seal a new driveway?
Most contractors recommend a penetrating sealer after it cures, then every few years, especially where winters bring freeze-thaw and de-icer.
How long before I can drive on a new driveway?
Usually about a week for a car, longer for anything heavy. Your contractor will tell you for your mix and the weather.
