Concrete driveway building in Santa Fe NM - a slab that holds up under your cars

A concrete driveway in Santa Fe usually costs about $9 to $19 per square foot installed, which is the going rate around town, not our price. Where yours lands depends on the size, the thickness, how much digging and rock the base takes and any work at the street end. I'll give you your own figure in a written estimate after I've seen the site.

It usually is if you'll park anything heavy, because a 5-inch slab costs roughly 20% more in concrete than a 4-inch one and carries nearly 50% more load. You're weighing a bit more concrete money against a drive that takes much heavier trucks, and we talk that through at the estimate before we price it.

You need a city permit when the new driveway crosses a sidewalk or the public right-of-way, or needs a curb cut, and the City of Santa Fe's public works department issues it from an application with a plan showing the drive and the cut. If that piece doesn't meet the permit's conditions, the city can revoke the permit and have you rebuild the drive to its standards at your cost, so we handle the paperwork and build that end to match. For a drive that stays on your own lot, public works is the place to ask, and every construction site in the city has to follow the city's stormwater runoff rules. Outside the cities of Santa Fe, Edgewood and Española, Santa Fe County requires its own development permit for building and grading, except on Pueblo lands.

Later than it looks, because concrete keeps gaining strength well after you can walk on it, so its color or how hard the top feels won't tell you it's ready for a heavy load. Keep cars off the edges and corners early on, since those need protecting from early traffic, and we'll tell you when your slab is ready based on the pour and the weather.

Most of the time it's the ground under it, because a slab on soft or shifting soil moves with the dirt. Many western states have expansive soils, which swell and shrink with moisture, and the usual answer there is a crushed rock layer under the slab, deeper the worse the soil. Collapsible soils are common in New Mexico too and have damaged roads around the state, so if your soil is a question mark, a soils engineer can tell you how much base the job needs before anyone pours.

Pour early enough that the slab can cure and dry out before freezing nights start, and keep deicers off the new concrete. Winter guidance from Michigan's concrete industry says freezing and thawing before new concrete has cured and air dried, plus early deicing chemicals, greatly raise the chance of scaling, which is the top flaking off in thin chips. If you're calling late in the season, we'll sort out the timing at the estimate.
