Exposed Aggregate Concrete: Pros, Cons, and Best Uses

Tue, 03 Mar 2026 12:45:37 GMT

Exposed aggregate is a decorative finish created by removing the top layer of cement paste to reveal the stones in the mix. Contractors apply a surface retarder (a chemical that slows surface hardening) right after the pour, then wash the paste away once the slab can hold the stone in place. Aggregate options range from river gravel to colored quartz, making it a popular upgrade for custom concrete patios and driveways.

The Pros of Exposed Aggregate Concrete

Exposed aggregate offers real advantages for Houston homeowners who want more than a plain gray slab, without the upkeep stained or painted surfaces require.

Traction and Slip Resistance

The textured surface provides natural grip underfoot. Houston's heavy annual rainfall means smooth concrete gets slippery fast. Exposed aggregate adds traction to patios, pool decks, and walkways without wearing off.

Durability and Longevity

When installed with proper base prep and control joints to account for Houston's expansive clay soil, exposed aggregate can last 30 or more years. The stones are embedded in the slab, not applied to the surface. There’s nothing that will peel, chip, or wear through.

Low Maintenance

Unlike stained or painted surfaces, exposed aggregate doesn't rely on a top layer that can degrade. Sealing every 2 to 3 years helps, but the finish doesn't depend on it.

Design Variety

River gravel for a natural, organic look
Colored quartz or glass for a more tailored aesthetic
White aggregate for a bright, coastal-style surface
Mixed stone sizes for texture variation

That range gives Houston homeowners real visual options, from Katy and Cypress to Bayt

The Cons of Exposed Aggregate Concrete

The tradeoffs are worth knowing before you commit.

Rough Underfoot

The texture that provides grip can feel rough on bare feet, especially when larger stones are used. Smaller pea gravel is smoother but less visually dramatic, a tradeoff worth discussing with your contractor before the mix is specified.

Harder To Repair Seamlessly

If a section cracks or spalls (surface flaking from moisture beneath the slab), matching the repair to the original surface is genuinely hard. Aggregate mix, stone color, and wash depth all affect how the patch looks. Reviewing the types of concrete damage helps homeowners catch problems before repairs get costly.

Higher Upfront Cost

More labor goes into exposed aggregate than a standard broom-finish slab. Decorative concrete in Houston typically ranges from $12 to $25 per square foot versus $8 to $15 for standard. On large concrete driveway installations , that gap adds up.

Aggregate Can Loosen Over Time

Surface stones can loosen if the slab wasn't properly cured or the base shifts under Houston's clay soil. Routine sealing slows this process on high-traffic surfaces.

Where Exposed Aggregate Works Best in Houston

Exposed aggregate is well-matched to surfaces where aesthetics, grip, and longevity all matter: patios, front walkways, pool coping, and driveway aprons. It's less suited for pool decks with heavy barefoot traffic or large commercial surfaces where patches and repairs tend to show.

For homeowners who want a finish built for Texas heat and heavy rainfall without constant upkeep, exposed aggregate delivers a better long-term return than coated alternatives.

Frequently Asked Questions

Exposed aggregate concrete comes with real strengths like natural slip resistance, 30-plus-year durability, and design variety, alongside genuine tradeoffs like higher upfront cost and difficult repairs. After installing countless exposed aggregate surfaces for homeowners across the Greater Houston area, Concrete Specialists of Texas breaks down exactly where this finish earns its place and where it doesn't.

If you've been going back and forth between a broom finish, a stamped surface, and exposed aggregate, you're not overthinking it. These finishes have genuinely different performance profiles. In Greater Houston's climate, those differences show up faster than they would in a drier market.

What Is Exposed Aggregate Concrete?

Does exposed aggregate concrete crack more than regular concrete?

Exposed aggregate isn’t inherently more prone to cracking than standard concrete. The risk of cracking depends on base preparation, control joint placement, and slab thickness—not the finish type. In Houston's clay soil, proper base compaction and adequate joint spacing are what prevent cracking, regardless of the surface finish.

How long does exposed aggregate concrete last in Houston?

With proper installation and sealing every 2 to 3 years, exposed aggregate in the Greater Houston area can last 30 or more years. Houston's climate spares concrete from freeze-thaw cycles, the primary cause of failure in colder markets. Concrete Specialists of Texas matches slab thickness and control joint spacing to Houston's soil conditions on every install.

Can exposed aggregate concrete be sealed?

Yes, and it should be. Sealing exposed aggregate every 2 to 3 years protects the aggregate stones from loosening, brings out the stone's natural color, and helps prevent moisture from working into the surface. A penetrating or film-forming concrete sealer both work, though film-forming sealers tend to enhance visual depth more noticeably on textured aggregate surfaces.

Choose the Right Concrete Finish for Your Houston Project

Exposed aggregate is the right choice when the application matches its strengths: surfaces that need grip, projects where durability matters more than easy repairs, and homeowners who want visual character without a coating to maintain.

Texas ADA Ramp Compliance: What Builders and Businesses Need to Know

Mon, 02 Feb 2026 14:43:13 GMT

A non-compliant ADA ramp is more than a concrete-related problem. It’s a legal liability waiting to happen. In Texas, businesses with accessible routes that fail federal standards can face Department of Justice complaints, private lawsuits, and expensive remediation after a failed inspection.

The good news is that compliance is straightforward when you work with a contractor who actually knows the specifications. Concrete Specialists of Texas installs ADA-compliant ramps for commercial properties across Greater Houston and Southeast Texas . In this guide, we cover what builders and business owners need to understand before the first form is set.

What ADA Ramp Requirements Actually Cover in Texas

The Americans with Disabilities Act (ADA) sets the federal baseline, while ADA Standards for Accessible Design apply in Texas just as they do everywhere else—but state and local jurisdictions can layer additional requirements on top.

The Texas Accessibility Standards (TAS), administered by the Texas Department of Licensing and Regulation, govern new construction and alterations across the state. When the two sets of standards differ, the more restrictive one applies. Most Houston-area commercial projects must satisfy both.

Core Federal Requirements

The core federal requirements are specific:

Slope Ratio: Ramp runs must not exceed 1:12, meaning for every inch of vertical rise, you need at least 12 horizontal inches of run. A 6-inch elevation change requires a minimum 6-foot ramp.
Width: At least 36 inches clearance between handrails
Landings: Required at the top and bottom of every run, at least 60 inches long and as wide as the ramp itself
Handrails: Required at heights between 34 and 38 inches
Edge protection: Mandatory on all ramp runs
Surface texture: Required for traction; not an optional upgrade

The Details That Matter Most for Ramp Installation

Two requirements cause the most compliance failures in field inspections: slope accuracy and surface texture.

Slope Accuracy

A slope that measures 1:11 instead of 1:12 is non-compliant under ADA and TAS standards. That fraction of a degree isn’t something you eyeball. It requires proper grading, laser-level verification, and experienced formwork.

On commercial properties in Deer Park and La Porte, where older concrete infrastructure is common and site grades are rarely uniform, getting the slope right often means more site prep than owners expect.

Surface Texture

Surface texture matters because a smooth concrete finish becomes a slip hazard in wet conditions. Houston's heavy annual rainfall increases that risk. A broom finish—the standard for exposed exterior concrete—provides enough texture to satisfy ADA traction requirements while still being manageable for wheelchair users and pedestrians alike.

Exposed aggregate finishes can work in some applications, but the aggregate size and profile need to stay within ADA guidance for surface regularity. This is an area where a concrete contractor with commercial concrete experience makes a real difference compared to a provider who primarily works residential jobs.

Common Ramp Compliance Failures on Houston Commercial Properties

We see the same issues come up again and again when fixing ramps on Houston-area commercial properties.

Uneven Settlement From Poor Sub-Base Prep

The most common is a ramp that was built to the right slope but settled unevenly over time because the sub-base wasn’t properly compacted. Houston's expansive clay soil shifts with seasonal moisture changes. Clay swells when wet and shrinks when dry. A ramp without a properly prepared base will eventually drift out of grade. This isn’t hypothetical; it’s the predictable outcome of skipping compaction and base prep in this soil type.

Flat Landings That Don't Drain

A second frequent issue involves the landing at the base of the ramp. Codes require that landing to drain away from the ramp, but many installations leave the concrete flat. Standing water accumulates, creates a hazard, and introduces moisture into the concrete over time. A properly designed ramp system accounts for drainage slope on the landing without compromising the ramp run's own slope requirements.

Non-Compliant Accessible Routes

Connecting sidewalk and accessible route repairs to the ramp project matters too. A compliant ramp connected to a deteriorating, uneven sidewalk still produces a non-compliant accessible route under ADA rules. The whole path from parking to entrance must meet standards, not just the ramp itself.

Get Your Ramp Right the First Time

Building an ADA-compliant ramp isn’t something that should be figured out as you go. The slope tolerances are tight, the documentation requirements are real, and remediation after a failed inspection typically costs significantly more than getting it right from the start.

7 Different Types of Concrete Damage: A Homeowner’s Guide

Mon, 05 Jan 2026 12:55:47 GMT

As a homeowner in the Greater Houston area, you understand the importance of maintaining your property. Your concrete surfaces, from your driveway to your patio, play a crucial role in your home’s curb appeal, functionality, and value. However, our region’s unique climate and soil conditions can take their toll on your concrete, leading to various forms of damage.

Concrete Specialists of Texas believes in empowering homeowners with the knowledge to identify and address these issues promptly. This guide will walk you through seven common types of concrete damage we see in the Houston area and what they mean for your property.

1. Cracking

Cracks are one of the most common issues. While not all cracks are a cause for alarm, it’s essential to understand their origin. Plastic shrinkage cracks are fine, surface-level cracks that occur when the concrete is still curing. These are generally not a structural concern. However, settlement cracks, which are wider and more significant, can indicate underlying soil issues.

Houston’s expansive clay soil is notorious for causing this type of damage. If you notice large, growing cracks in your foundation or driveway, it’s time to call the professionals. We can assess the damage through our residential concrete services and recommend the best course of action.

2. Spalling and Scaling

Have you noticed the surface of your concrete flaking or peeling away? This is known as spalling or scaling. This type of damage is often the result of poor finishing or an improper concrete mix, but it can also be caused by freeze-thaw cycles.

Though they’re less common in Houston, spalling and scaling can still happen during our colder winters. The high humidity in our area can also cause moisture to seep into the concrete, leading to surface deterioration. Addressing spalling early can prevent more extensive damage to concrete driveways and other surfaces.

3. Discoloration and Stains

Discoloration might not seem like a structural issue, but it can certainly detract from your home’s appearance. Stains from oil, grease, and rust are common on driveways and in garages. Additionally, the intense Texas sun can cause discoloration over time. In some cases, discoloration can also be a sign of moisture or chemical reactions within the concrete.

4. Pitting and Pop-outs

Pitting and pop-outs are small holes or craters that appear on the surface of your concrete. These are often caused by porous materials, like shale or wood, that were accidentally mixed into the concrete. When these materials absorb moisture and then expand, they can cause a small piece of the concrete to “pop out.” While a few small pits may not be a major concern, extensive pitting can weaken the concrete surface and make it more susceptible to further damage.

5. Settling and Sinking

Uneven concrete surfaces are a significant safety hazard and a clear sign of underlying problems. As we mentioned earlier, Houston’s expansive clay soil is a major culprit. When the soil beneath your concrete slab expands and contracts with changes in moisture, it can cause the slab to settle or sink. This is a common issue for concrete patios and walkways. Our team has the expertise to level and restore your sunken concrete, ensuring a safe and even surface.

6. Curling

Curling is when the edges of a concrete slab curl upwards, creating a slight dish shape. This is typically caused by a difference in temperature and moisture between the top and bottom of the slab. The top surface dries and shrinks faster than the bottom, causing the edges to lift. This can create a tripping hazard and indicates that the slab was not properly cured. While more common in large commercial projects, we also see this in residential settings.

7. Crazing

Crazing is a network of fine, random cracks that create a map-like pattern on the surface of the concrete. This is usually caused by the concrete surface drying too quickly during the curing process. While crazing is a cosmetic issue that typically doesn’t affect the structural integrity of concrete, it can be a sign of a rushed or improper installation.
