Concrete contractor in Four Square Mile, CO - slabs on a packed, drained base
Form & Finish Aurora Concrete is a concrete contractor based in Aurora that pours driveways, patios, sidewalks, garage floors and footings in Four Square Mile, with the base dug out and packed before any concrete goes down.
Concrete work in Four Square Mile, under county rules
Aurora and Denver surround Four Square Mile on every side, but it isn't part of either. It's unincorporated Arapahoe County, so the county, not a city, sets the building rules, issues the permits and licenses the contractors here. I come out to look at your job and write the estimate myself, and our crew does the work with me on site.
The price mostly follows the digging and base work, the size and thickness of the slab, and the finish, from a plain broom finish, the light texture that keeps it from getting slick, to stamped. The schedule turns on the county permit when one's needed, the weather and curing, the wait while fresh concrete gains strength. Your written estimate shows what's included and what isn't.
We're based in Aurora and do the same work across the cities around it, including Commerce City and Cherry Creek. Most of our calls come from homeowners, with some from property owners and builders who need a slab or footings poured. If your city isn't on this site, call and ask.

Concrete driveway building

Walks to the front door, side gate or backyard are flatwork, the trade's word for flat slabs. We replace them once sections lift into a trip hazard.

A cracked, sunken or oil-soaked garage floor can be broken out and replaced. We size the new slab for the cars and whatever else you park in there.

Color, stained finishes and saw-cut patterns give a plain slab some character. I'll tell you plainly when an upgrade pays off and when it won't.

Where a slope washes onto the drive, a poured retaining wall holds the soil back. The drainage we build behind it matters as much as the wall.

Floors for basements, shops and outbuildings, poured over a packed base with plastic underneath when the space needs to stay dry.

A pool deck needs a surface that isn't slick when wet and slopes water away from the pool. We pour new decks and replace heaved ones.

When front steps crumble or pull away from the house, we form and pour new ones with every step the same height, so they feel even underfoot.

For a new garage, addition or outbuilding, a slab foundation is often the floor and footing poured together. The subgrade, the ground it sits on, comes first.

Footings and foundation walls for new homes, additions and garages, built from the builder's plans. We work with property owners and builders as well as homeowners.

Parking areas for a shop, rental or small business, where heavier traffic calls for a thicker slab, steel rebar to hold it together and planned drainage.

If you're adding a deck, porch or addition, footings carry its weight into the ground. We dig and pour them to the depth the plans call for.

When a slab or foundation has settled, leaving cracks or sticking doors, raising it can bring it back toward level without a tear-out.

We saw-cut concrete for doorways and trenches, or to take out a failed section without breaking up the good slab around it.

When an old slab needs more than a patch
A crack that stays flat on both sides is usually cosmetic, and sealing it or using concrete cutting to take out one bad section can be enough. When one side sits higher than the other, the ground under it has moved. If a house slab has dropped but is otherwise sound, foundation raising can lift it back toward level.
When the slab is broken in many places, holds water or tips toward the house, a patch only hides the problem, so we tear it out, fix the base and drainage, and pour a new driveway or patio. If the budget's tight, I'd cut the stamped finish before the base work, because the base is what keeps the slab flat.
Semi-rural lots in Four Square Mile
The county's plan reported large parts of the area with a rural or semi-rural feel, dirt streets, horses and goats, and entire blocks on wells and septic. If your place is like that, a new driveway may meet a dirt road instead of a curb, and a barn or shed may need a floor too.
Parts of the area take in the Cherry Creek channel, which the plan lists along with a public trail and the 100-year floodplain. When a lot is near the creek, the county's permit may need sign-off from its floodplain administrator, so we ask about that before we plan the pour.
What to have ready before your estimate
Where your septic and well are
If you're on a septic system or a well, mark the tank, the drain field and the well line, or bring any drawing you have. We won't pour over a drain field, because it needs open ground and access, and that can change where a driveway goes.
Where the water goes now
Walk the area after a hard rain or a snowmelt and note where water stands or runs toward the house. That tells me more than anything I'll see on a dry day, and drainage sets the slope of the new slab.
What the slab has to carry
Tell me what will sit or drive on it, like cars, a truck and horse trailer, or a hot tub. Heavier loads mean a thicker slab and more steel, so it's better to know before I write the estimate than after the pour.
Concrete questions from Four Square Mile homeowners
Who issues concrete permits in Four Square Mile, CO?
Arapahoe County does, because Four Square Mile is unincorporated, and the county's Building Division takes permit applications electronically. We check with the county for your address, and when the job needs a permit we get it before work starts. A permit lapses if work doesn't start within 180 days of issue, so we don't pull one early.
Does a concrete contractor need a county license in Four Square Mile?
Yes, a county license is required to do permit-required building or construction in unincorporated Arapahoe County, and the county's Building Division issues it. Licenses expire a year after they're issued or renewed, and a contractor without an active one can't pull permits or keep working under one, so ask to see it. We're fully licensed and insured.
Do I need a permit to pour a slab for a small shed in Four Square Mile?
The county lists one-story detached sheds up to 120 square feet, not used to store vehicles, among work that needs no building permit. Whether the slab under one does is a question we put to the county for your address before we pour, since even exempt work can need Planning and Zoning approval.
How deep do concrete footings need to be in Four Square Mile, CO?
The county's guide for new single-family homes lists a frost depth of 36 inches, one of the design criteria new-home plans have to meet. For a garage, addition or deck, we dig to the depth on the plans and confirm it with the county, because a footing above the frost line can heave when the ground freezes.
Will my new concrete driveway crack like the old one did?
Some fine cracking is normal because concrete shrinks as it cures, but a new slab shouldn't break up and sink the way a badly prepped one does. We dig out and pack the base, check where water runs, and cut control joints, shallow grooves that give cracks a straight line to follow, before the slab cracks on its own.
How long until I can drive on a new driveway in Four Square Mile?
You stay off it until the concrete has cured enough to take the weight, and you can walk on it days before you can drive on it. Cold slows curing and midday heat can leave a weak, dusty top, so I'll push a pour back rather than rush it into bad weather.
