Sloped drives on the west side
Many driveways west of MoPac climb or drop steeply from the street. On a slope, the finish matters more than usual: a medium to heavy broom texture gives tires grip when the surface is wet. The transition at the street and at the garage has to be shaped so cars don't scrape.
Water runs fast on a steep slab. Without a plan, it sheets down the driveway and into the garage or across the neighbor's yard. Trench drains, a slight cross-slope or a curb along one edge can direct it where it belongs.
Building on rock means breaking out high spots for an even slab thickness and filling low spots with compacted base. Thin spots over rock crack easily, so the slab should be uniform even where the ground isn't.

Replacing driveways on clay
East of I-35, many driveways show long cracks, settled panels near the garage and edges that have curled with the seasons. When the damage is widespread, replacement with a better base, more steel and well-spaced joints usually lasts far longer than the original.
On expansive clay, the base is the main defense. Removing soft soil, compacting the subgrade and placing select fill or crushed base reduces the movement the slab sees. Rebar held at mid-depth keeps any cracks tight.
Downspouts and sprinklers near the driveway edges should be redirected. Uneven moisture along one edge is a common reason driveways crack lengthwise.

Impervious cover and approaches
Inside Austin city limits, driveways count toward the lot's impervious cover. Widening a driveway or adding a parking pad can push a lot over its limit, so check the numbers first. Ribbon driveways, with a planted strip in the middle, are one way to reduce coverage.
Work in the public right-of-way, including the approach and curb cut, involves the city and its standards. Ask your contractor who arranges the permit and inspection, and whether that's in the estimate.
In Round Rock, Leander and Georgetown the city codes differ, and HOAs in newer subdivisions often have rules on driveway width and finish. Check both before finalizing the design.

Thickness, steel and joints
Most residential driveways are poured four to five inches thick, with thicker edges or a thicker apron where heavier vehicles cross. Rebar on chairs is common practice on Austin's moving soils.
Joints should be spaced so panels stay roughly square, typically eight to twelve feet apart on a four-inch slab, with extra joints at corners and where the driveway changes width.
Isolation joints separate the driveway from the garage slab, the street and any walls so each can move without cracking the other.

Curing in Austin weather
Hot, dry, windy days pull moisture out of fresh concrete quickly. Early-morning pours, curing compounds or wet curing keep the surface from cracking before it gains strength.
Expect to walk on a new driveway after a day or two and drive on it after about a week, with heavier vehicles waiting longer.
A penetrating sealer after curing helps resist oil stains and water, and can be renewed every few years.

Room for trailers, boats and work trucks
Plenty of Austin-area households park a boat for Lake Travis, a camper or a work truck beside the house. Those vehicles concentrate a lot of weight on small areas, especially at trailer jacks and tongue stands, and they tend to sit on the same spot for months.
A parking pad or driveway section meant for them should be thicker than a standard drive, typically with a thickened edge, closer steel and a well-compacted base, and its approach should be shaped so the trailer doesn't drag. If the pad will sit beside the house, check HOA rules on where trailers may be stored and how the pad affects your lot's impervious cover.
How we work
Step by step

Curing guidance and a date for driving on it.
What it costs
Driveway prices depend on the size, removal of the old slab, rock or clay preparation, thickness and steel, the approach and the finish. Steep sites add forming and finishing time.
Questions
Concrete Driveways — asked and answered
Does a wider driveway need city approval in Austin?
It can, especially if it changes the approach or pushes the lot over its impervious cover limit. Check before work starts.
How do I keep a steep driveway from being slippery?
A heavier broom finish and avoiding glossy sealers help. Exposed aggregate also gives good traction.
Why does my driveway crack along its length?
Usually uneven moisture along one edge on clay soil, from sprinklers, downspouts or a planting bed.
How long does a driveway replacement take?
Typically a few days of work, plus about a week of curing before you drive on it.
Can a cracked driveway be partly replaced?
Yes. Badly damaged panels can be cut out at the joints and repoured, leaving sound panels in place. The new concrete won't match the old color exactly at first, but it blends over time.
