Concrete vs Pavers

$14/sq ft Concrete. $21/sq ft Pavers. Same Outdoor Living.

The most common question we get about patios: concrete or pavers? Both create a durable outdoor living surface. The difference is cost, maintenance, and aesthetic.

Poured concrete starts at $14 per square foot in Austin. Pavers start at $21 per square foot. For a typical 400 square foot patio, that is $5,600 for concrete vs $8,400 for pavers — a $2,800 difference. Scale that to a 1,000 square foot outdoor living area and the gap widens to $7,000.

But the cost comparison tells only half the story. Concrete is a monolithic slab — no joints for weeds, no settling units, no polymeric sand to replenish. Pavers are individual units set on a sand bed — they can shift, settle unevenly, and allow weed growth through joints. Pavers do offer one advantage: if a single unit cracks, you can replace that one unit without disturbing the rest.

Where concrete wins outright is in decorative flexibility. Marbled concrete creates organic veining patterns that look like natural stone. Board-formed concrete captures wood-grain texture from actual lumber forms. Acid stain creates translucent, layered color that no paver can replicate. These are architectural finishes that transform a $14/sq ft material into something that competes visually with $30+ natural stone — at a fraction of the cost.

Five Ways to Finish Concrete

Marbled Concrete
$18–$24 / sq ft

Two or more integral concrete colors are poured simultaneously and hand-swirled with trowels to create organic veining. The color runs through the full depth of the slab — it cannot wear off or delaminate. Each pour is unique. Works best with earth tones: charcoal and cream, tan and walnut, grey and white. The signature Red Agave finish for high-end outdoor living spaces.

Board-Formed
$22–$30 / sq ft

Actual lumber (typically rough-sawn cedar or pine) is used as formwork along the slab edges or as interior divider strips. The wood grain transfers into the concrete surface, creating a texture that reads as natural wood but performs as concrete. Often combined with a smooth-troweled or broom-finished interior field. The contrast between organic wood texture and clean concrete is the hallmark of modern architectural hardscape.

Acid Stain
$6–$12 / sq ft (over existing)

A chemical reaction between metallic salts and the lime in concrete creates translucent, variegated color. Unlike paint (which sits on top), acid stain penetrates and becomes part of the concrete. Colors are earthy and translucent: amber, cola, turquoise, terra cotta. Can be applied to new pours or existing concrete — one of the few ways to transform an old grey slab into architectural hardscape without demolition.

Exposed Aggregate
$16–$20 / sq ft

The surface paste is washed away after the concrete sets to reveal the stone aggregate underneath. The result is a naturally textured, slip-resistant surface with the visual depth of a gravel path but the structural performance of a concrete slab. Aggregate can be selected for color — river rock, crushed granite, or limestone. Excellent for pool surrounds and walkways where slip resistance matters.

Standard Broom Finish
$14 / sq ft

A steel trowel creates a smooth surface, then a broom is dragged across the wet concrete to create parallel texture lines for slip resistance. The most cost-effective option and the baseline for all other finishes. Can be colored with integral pigment ($2–$4/sq ft additional) for a warmer tone than standard grey. The workhorse finish for driveways, walkways, and utility areas.

Engineering

Why Austin Patios Crack — and How We Prevent It

Austin sits on some of the most challenging soil in Texas for concrete work. East of I-35, Houston Black clay expands and contracts dramatically with moisture cycles — swelling when wet, shrinking and cracking when dry. West of MoPac, thin soil over fractured limestone creates uneven bearing capacity. Between the two, the Blackland Prairie transition zone combines both problems.

Most patio cracks in Austin are caused by soil movement, not concrete failure. A slab poured directly on native clay will heave and crack within 2–3 years as the soil goes through wet/dry cycles. The solution is base preparation:

  • Excavation: Remove 6–8 inches of native soil across the full patio footprint
  • Compacted base: 6 inches of crushed limestone (flex base), compacted in 2-inch lifts with a plate compactor to 95% Proctor density
  • Rebar reinforcement: #4 rebar on 18-inch centers, supported on chairs to maintain position in the middle third of the slab
  • Slab thickness: Minimum 4 inches for patios, 6 inches for areas supporting outdoor kitchens or heavy planters
  • Control joints: Saw-cut within 12 hours of pour at 8–10 foot intervals — gives the concrete a predetermined place to crack
  • Slope: Minimum 1/8 inch per foot away from the house foundation for drainage

This base preparation adds $2–$3 per square foot over a slab poured directly on native soil. But it is the difference between a patio that lasts 5 years and one that lasts 50. Every Red Agave patio includes full base preparation — it is not an upgrade or add-on.

Design Integration

Concrete as the Foundation for Outdoor Living

A poured concrete patio is the structural base for the rest of the outdoor living design. Red Agave integrates the slab with every other element of the landscape:

  • Steel edging: 1/4-inch structural steel edging separates concrete from turf, gravel, and planting beds. The steel develops a Corten patina that contrasts with the concrete surface. Steel edging also serves as the form for the concrete pour — it stays in place permanently rather than being stripped
  • FCOB lighting: 24V FCOB LED strips are embedded in channels cast into the slab edge or mounted along steel edging. The continuous light line defines the patio perimeter after dark without visible fixture points
  • Fire pit integration: Custom fire pits are formed directly into the concrete pour with a thickened slab edge, gas line penetration, and fire ring mounting. No separate foundation or pad required
  • Outdoor kitchen pads: Outdoor kitchen areas get a 6-inch slab with additional rebar to support countertop, grill, and equipment weight. Utility trenches for gas, water, and electrical are cast into the slab
  • Grade transitions: Where the patio meets sloped terrain, steel retaining walls hold the grade change. The concrete slab ties into the wall footer for a monolithic connection
  • Planting pockets: Openings left in the concrete pour for specimen trees, native plantings, or decorative boulders. The concrete edge around the pocket gets board-formed or steel-edged treatment

Frequently Asked Questions

Who builds custom concrete patios in Austin TX?
Red Agave Landscape pours custom concrete patios starting at $14/sq ft. Finishes include marbled color swirl, board-formed, acid stain, and exposed aggregate. Every slab includes rebar, compacted base, and control joints. Free consultation at 512-695-7566.
How much does a concrete patio cost in Austin?
Poured concrete starts at $14/sq ft (broom finish). Marbled runs $18–$24/sq ft. Board-formed runs $22–$30/sq ft. A 400 sq ft patio costs $5,600 to $9,600 depending on finish. Compare to pavers at $21/sq ft ($8,400 for 400 sq ft).
What is marbled concrete?
Marbled concrete is a decorative finish created by swirling two or more colored concrete mixes during the pour. The color runs through the full depth — it cannot wear off. Each pour creates a unique pattern. The technique produces organic veining similar to natural marble at a fraction of the cost.
Is concrete cheaper than pavers?
Yes. Concrete starts at $14/sq ft vs pavers at $21/sq ft. For a 400 sq ft patio, that is $5,600 vs $8,400 — $2,800 savings. Even marbled concrete at $18–$24/sq ft is comparable to or less than pavers. Concrete also has lower maintenance with no joint re-sanding or unit resetting.
How long does a concrete patio last in Austin?
25 to 50 years with proper base preparation. The keys are 6 inches of compacted crushed limestone base, minimum 4-inch slab thickness, rebar reinforcement, control joints at 8–10 foot intervals, and correct drainage slope. Without base prep, Austin’s expansive clay can crack a slab in 2–3 years.
Does concrete crack in Austin’s heat?
Cracking is primarily caused by soil movement, not heat. Control joints give concrete a predetermined place to crack. Rebar holds the slab together if a crack develops. Proper base preparation prevents the most common cause: expansive clay shrinking and swelling with moisture cycles.
What concrete finishes are available?
Five categories: marbled ($18–$24/sq ft), board-formed ($22–$30/sq ft), acid stain ($6–$12/sq ft over existing), exposed aggregate ($16–$20/sq ft), and standard broom ($14/sq ft). Finishes can be combined — board-formed edges with marbled interior is a popular combination.
Can you pour concrete over an existing patio?
Sometimes. A 2–3 inch overlay works if the existing slab is structurally sound and not heaving. If the existing slab is cracked from soil movement, an overlay will crack in the same places. In most cases, removing the old slab ($3–$5/sq ft) and pouring new with proper base preparation is the better long-term investment.
