A lot of driveways across the Metro East are due for replacement. The old slab has cracked, heaved from winters, or just worn down to a surface that's slick when wet and rough-looking year-round. When it's time to replace it, most homeowners want something that holds up and looks decent without spending what natural pavers cost. Exposed aggregate is worth knowing about.
What Exposed Aggregate Means and How We Pour It
Exposed aggregate concrete starts the same way any slab does. We pour standard concrete, set the forms, and prepare the base. The difference is in the finish. Before the surface sets fully, we apply a surface retarder that slows the curing of the top layer. Then we wash or brush off that thin layer of cement paste to expose the stone aggregate underneath.
What's left is a surface with visible rock embedded in it. The stones are part of the original concrete mix. You're not adding a coating or a veneer. The texture you see is the actual structure of the slab.
That texture does two things. It gives the driveway a naturally slip-resistant surface, which matters on a driveway that sees rain, ice melt runoff, and Illinois winters. It also gives the finished surface a high-end appearance without the cost of pavers or the maintenance demands of stamped concrete.
The aggregate mix can be adjusted. River gravel gives a rounded, smooth-stone look. Crushed stone gives sharper texture and more visual contrast. The color of the stone plays a role too. We'll walk you through what's available and what will suit your property.
What we don't do is pour the slab without proper base preparation first. Cracking and settling almost always trace back to a weak or improperly graded base. We compact the subgrade, set the correct thickness for your traffic load, and place reinforcement before a single yard of concrete is poured. The aggregate surface won't matter much if the slab below it isn't built right.
When You Might Be Looking at Exposed Aggregate
A few situations come up often.
You're replacing an old driveway and want something better than the plain broom finish that was there before. A broom finish works fine, but exposed aggregate gives more character and slightly better traction without a major jump in cost.
Your current surface is slick when wet. The textured profile of exposed aggregate gives tires and feet more to grip. For a driveway that slopes toward a garage or has a curved approach, that traction difference is real.
You want a finished look that holds up over time without ongoing maintenance. Unlike a stamped concrete surface that relies on color and pattern in a thin surface layer, exposed aggregate shows material that goes through the full depth of the slab. The appearance is durable.
You're building new and want the driveway to complement a home exterior without matching the cost of natural stone. Exposed aggregate reads as high-end from the street. It's concrete, but it doesn't look like a plain gray slab.
How the Project Works, Start to Finish
Estimate. We come out, measure the area, look at the site conditions, and talk through your options. If there's an old slab to remove, we note that. You get a clear price before anything starts.
Tear-out and haul-away. If there's existing concrete, we break it out and haul it off with our own trucks. You don't need to line up a separate demolition crew or arrange debris removal. We handle it in-house as part of the job.
Base prep. We grade the area, compact the subbase, and set the correct slope for drainage. This step determines how long the new slab lasts.
Forms and reinforcement. We set forms to your dimensions and place rebar or wire mesh based on the load requirements.
Pour and finish. We pour the concrete, screed and level the surface, apply the retarder, and then wash or brush the top layer at the right time to expose the aggregate evenly.
Curing and cleanup. We leave the slab to cure, remove forms, and clean up the site. You can walk on it within a day or two. We recommend waiting about a week before driving on it.
Sealing. Exposed aggregate benefits from sealing after it cures. Sealer protects the surface from staining and enhances the color of the stone. We can discuss whether sealing is part of your project scope during the estimate.
What to Expect on Cost
Exposed aggregate costs more than a standard broom-finish driveway. You're paying for the additional materials and the extra steps in the finishing process. It costs less than natural stone pavers and less than most stamped concrete with multiple colors.
What affects the price: square footage, whether tear-out and haul-away are needed, site conditions (slope, drainage, access), the aggregate mix selected, and whether sealing is included.
The only way to give you an accurate number is to see the project in person. Estimates are free. We come out, measure, and give you a written price before any work starts. No pressure, no obligation.

Where We Work
We pour exposed aggregate driveways across the three-county Metro East area. That includes O'Fallon, Belleville, Swansea, Fairview Heights, Shiloh, and the rest of St. Clair County. We also serve Edwardsville, Collinsville, Glen Carbon, Troy, and throughout Madison County. Down in Monroe County, we work in Waterloo, Columbia, and the surrounding towns.
If you're not sure whether your area is in our range, call us and ask. We'd rather tell you directly than have you guess.
