Side-by-side comparison of exposed aggregate concrete patio (left, natural pebble texture) and stamped concrete patio (right, brick pattern with color) — two decorative finish options for San Antonio outdoor slabs
Exposed aggregate (left) shows the natural stone in the slab for a rugged, textured surface. Stamped concrete (right) prints a brick, slate, or stone pattern with added color. Both are decorative finishes over a real concrete slab.
Quick Answer

Exposed aggregate shows the stone in the slab and stays rugged and slip resistant. Stamped concrete mimics brick or stone with color and pattern. San Antonio sun fades stamp colors without sealer. Ted has 40 years in concrete, so call before you choose a finish.


Exposed aggregate or stamped concrete for a patio?

Pick exposed aggregate when you want natural stone texture and built-in grip. Pick stamped concrete when you want brick, slate, or stone patterns with color.

Both are decorative finishes over a real concrete slab. Strength still comes from the base, thickness, joints, and drainage. Planning a decorative concrete patio in San Antonio? Our decorative concrete page covers stamped, stained, and related upgrades; exposed aggregate is another option when you want texture without a full stamp pattern.

What is an exposed aggregate patio?

It is a concrete slab finished so the stone or gravel at the surface shows. The Portland Cement Association says exposed-aggregate finishes are rugged, slip resistant, and highly immune to wear and weather, and that they are ideal for patios and other horizontal slabs.

  • Look: Natural pebble or stone texture instead of a printed pattern.
  • How it is made: PCA describes seeding select aggregate into the surface, using gap-graded aggregate in the mix, or a special topping, then washing the surface paste to reveal the stone.
  • Common patio size: PCA notes that 3/8-inch pea gravel is commonly used for patios.
  • Exposure depth: PCA says depth of exposure should not exceed one-third of the average aggregate diameter.

Our maintenance guide also treats exposed aggregate as a standard patio finish that pairs well with a penetrating sealer for long-term care.


What is a stamped concrete patio?

Stamped concrete is poured concrete patterned and often colored to look like brick, slate, stone, or similar materials.

  • Look: Our stamped page names brick, slate, and stone looks without the upkeep of natural materials.
  • Color: Release colors and stains create contrast; UV and weather wash those colors out over time if the sealer is neglected.
  • Sealer: Unsealed stamped concrete absorbs stains and loses definition. A clean and reseal protects the pattern.

How do exposed aggregate and stamped patios compare?

They trade pattern for pebble texture. Neither one is automatically stronger; the slab underneath still has to be built right for San Antonio heat and clay soil.

Exposed aggregate Stamped concrete
Look Natural stone or pea gravel showing at the surface Brick, slate, or stone patterns with color
Grip PCA calls it rugged and slip resistant Depends on texture and sealer; glossy sealers can feel slicker when wet
Sun and color Texture stays; aggregate color is in the stone UV washes out release colors without sealer care
Upkeep Clean; penetrating sealer is a common long-term choice Clean and reseal to protect pattern and color
Best when You want texture and grip without a printed pattern You want a designed pattern that matches brick or stone

At walking distance, exposed aggregate reads as a textured natural surface and stamped concrete reads as a patterned one. The right choice depends on the look you want and how the slab gets wet not which one is structurally stronger.

Which finish gives better grip when wet?

Exposed aggregate usually has more natural texture underfoot. Stamped concrete grip depends on the pattern depth and whether the sealer is glossy.

Our stamped-vs-standard patio guide notes that stamped surfaces can feel more slippery with a glossy sealer and no traction additive, especially near pools and rain. Ask for a sample or a nearby patio you can walk on before you choose.


How does San Antonio sun age each finish?

Sun fades color and wears sealer on both finishes. Stamped color shows fade sooner when the sealer is gone; exposed aggregate shows more as a dull or dirty surface than as a lost printed pattern.

  • Stamped: The stamped page says UV and weather wash out release colors, and worn or missing sealer lets the slab absorb stains and lose definition.
  • Exposed aggregate: PCA highlights wear and weather resistance, but the slab still needs cleaning and sealing on a San Antonio schedule.
  • Either finish: Heat, clay soil, and storms still stress the slab underneath. No finish hides a patio that keeps cracking. See what concrete patio finish holds up in San Antonio heat.

San Antonio sun strips sealer faster than in cooler climates. When the sealer wears through, stamped release colors fade and the pattern loses contrast. A professional clean and reseal restores both no tear-out required on a structurally sound slab.

“I am beyond happy with the stamped concrete patio they created for me. The process was smooth, the team kept me informed, and the stain color is exactly what I envisioned.”

Does the finish change the price of a patio?

Yes. Finish type is one of the price factors on our service pages, along with square footage, access, demolition needs, and site prep.

The service pages do not publish dollar figures for exposed aggregate or stamped work. Stamping, color, and decorative steps add labor. You get the number in a free written estimate after a look at the site. For stamped budgeting context, see stamped concrete patio cost in San Antonio.


How do I choose between exposed aggregate and stamped?

Start with the look you want and how the patio gets wet. Then confirm the slab plan underneath matches San Antonio soil and drainage.

What else are homeowners asking?

These are the short answers people want before they book a quote.

Is exposed aggregate better than stamped concrete for a patio?

Exposed aggregate is better when you want natural stone texture and built-in grip. Stamped is better when you want brick or stone patterns with color. Strength still depends on the slab underneath.

Is exposed aggregate slippery?

The Portland Cement Association describes exposed-aggregate finishes as rugged and slip resistant, which is why they are used on patios and other outdoor slabs.

Does stamped concrete fade in San Antonio sun?

Yes. UV and weather wash out stamp release colors over time, especially when the sealer is worn or missing. A clean and reseal helps protect the pattern.

Can I put exposed aggregate on an existing patio?

Sometimes a decorative overlay or resurfacing can change the surface of a sound slab. A failed base still needs repair or tear-out. Get a free on-site look first.
