What does building a slab foundation in Durango involve?

Slab foundation building in Durango means pouring your home's ground floor as one concrete slab, set on footings, the buried concrete under its edges that carries the house. Done right, it gives you a floor planned for the soil under it, and most of the waiting happens before the dig, while the plans are reviewed.

Usually you've got plans, or at least a lot and a rough footprint, and you want to know what the ground floor takes before you commit. The price moves with the size of the slab, how much digging the footings and soil work take, and whether your plans need an engineer. The schedule mostly turns on permit review, then the weather once we're ready to dig. When I come out, I'll walk the lot and tell you plainly what we'd do.

How we build a slab foundation

I walk the lot first, and the soil questions get settled in the design before the permit goes in, so nobody's guessing once the ground is open. Our crew then digs the footings, packs the subgrade, the ground the slab rests on, and sets rebar, steel bars that hold the concrete together if it cracks. While the ground's open we keep the clay from drying out and keep water from sitting near the forms, because both make clay problems worse. We pour early in the day, since midday heat leaves a weak, dusty top, and then let the slab cure, the slow stretch where it gains strength, before anyone builds on it.

Not every plan suits a slab, and when the design calls for a different base under the house, that's our foundation installation work. If you're putting up a shop or a small commercial building, we also do concrete parking lot building, so the slab and the parking can be planned around the same drainage.

Slab foundation building under Durango's rules and soil

In Durango, any building permit your project needs has to be issued before construction or any ground disturbance, and digging out more than 10 cubic yards takes a separate permit from the city's engineering office. Which permits your slab needs is the city's call, and you can check the city's permit page before we talk. The city also wants foundation plans to show soil preparation details tied to any soil study, along with a confirmed bearing capacity, how much weight the ground can carry, which is why we settle the soil before anything is submitted.

Plenty of lots around here have clay that moves with the seasons and the sprinklers, and some western Colorado soils are still counted among the region's main geologic hazards for the damage they do to foundations. We see that ground on jobs all over Durango and the cities around it, so we treat the soil as part of the job, not something to find out about after the pour.

How a slab job runs with Durango Concrete Company in Durango

  1. Call or send the form

    Call (970) 844-8095 or fill out the form with your site address and what you're planning. We'll set a time for me to come out to the lot.

  2. I walk the lot myself

    I look at the ground and any plans or soil study you have, and I listen to what you want. You get a plain account of what we'd do, from the footing work to the soil prep to what's driving the price.

  3. We handle the permit paperwork

    We check what the city needs before anyone digs, and when a permit's needed we handle the application. The city asks applicants to allow at least 30 business days for review, longer if plans come back for changes, so we build that wait into your start date and aim for a complete set the first time.

  4. Our crew digs, forms and pours

    Our crew does the work, and I'm on site running it through the pour. When the slab's in, we clean up and walk it with you.

Why Durango homeowners hire Durango Concrete Company for slab foundations

  • I walk every job myself

    I come out to look at every job myself, and I'm on site running our crew through the pour. You're talking to the person who'll be standing there when the concrete goes in.

  • Licensed and insured for your job

    We're licensed and insured. The city requires contractors to hold a valid City of Durango business license, so it's fair to ask any crew you're weighing to show you theirs.

  • Your money goes under the slab

    When a budget gets tight, the base work is usually the first thing people want to cut, because nobody sees it once the concrete's down. I'd rather spend there and keep the top plain, since a nice-looking slab on poorly prepared ground can still crack and settle.

  • In business since 2023

    We've been in business since 2023, and I learned this trade pouring for new construction before moving to homes people live in. So we know a bare-lot pour, and we know how to keep a crew careful around a family's yard, cars and garden.

What matters most on a slab is getting the ground and the plans right before the first shovel goes in. Satisfaction guaranteed on every job. Tell us about your lot and I'll come out to walk it.

Questions about slab foundations in Durango

How deep do slab foundation footings need to be in Durango?

The city requires footings at least 32 inches below the undisturbed ground surface, and La Plata County's code lists the same 32-inch frost depth. That means a slab here starts with digging well below where the flat floor sits, which adds work and time before the pour. We plan the dig around that depth from the first visit.

What happens if I start a slab foundation in Durango without a permit?

The city charges triple the building permit fee for construction or excavation done without the proper permits. That's a costly way to save a few weeks, so we sort out what the city needs before anyone breaks ground.

What causes a slab foundation to crack or move on clay soil?

Clay that swells when it's wet and shrinks as it dries is the usual cause, and building without allowing for that movement in areas known for it is a very common source of property damage. So the slab design allows for the movement from the start. I'll be straight with you that small hairline cracks are normal in concrete, and they're a different thing from a slab that shifts.

Does my subdivision in Durango require an engineered slab foundation?

If you're building in Sky Ridge or Rock Ridge, yes, both subdivisions require a professionally engineered foundation system. Plan for an engineer's design from the start, and tell us your subdivision when you call so the schedule accounts for it.

How much does it cost to build a slab foundation in Durango?

On most slabs the biggest swings in price come from the ground, meaning how much soil has to come out or be reworked and whether an engineer's design is required. A simple rectangular footprint on a lot that's easy to reach usually costs less than one with lots of corners or tight access. You'll get a figure for your own job when I come out to walk it.

What is the best way to protect a new slab foundation from clay soil?

Keep water moving away from the house, starting with a site graded so it drains away before any landscaping goes in. Colorado State University Extension also advises planting no closer than five feet from the foundation unless the plants need very little water. We'll talk through where the water goes before we leave the job.

  • Foundation installation

    If your plans show a crawlspace or full stem walls instead of a slab on grade, we can form and pour that foundation too.

  • Concrete parking lot building

    A new shop or rental building often needs paved parking, and pouring it while our crew and equipment are already on the property can make the job simpler.
