Exposed Aggregate Concrete
Exposed aggregate is the finish that reveals what is actually in the concrete. Timing the wash and the retarder decides how much stone shows. It grips well and it hides wear better than a smooth finish.
Talk to us about the job
How the job runs
Walk the job first
Somebody comes out and looks at it. You cannot price concrete off a photo, because the questions that matter are what the ground is doing, where water goes, and how a truck gets in.
Say what it needs
We tell you what the job actually requires, including when that is less than you expected. A repair that will hold beats a replacement you did not need.
Build the base
Grade, correct the soft spots, compact in lifts. This is the part nobody sees and the part that decides whether the slab is still flat in twenty years.
Form, steel, pour
Forms braced for real pressure, steel on chairs at the right height, then placed and consolidated properly. Then finished at the right moment, which is the part you cannot rush.
What this job actually needs
The finish changes how it behaves
Texture is not only appearance. Broom and salt finishes grip when wet, exposed aggregate hides wear, a hard troweled surface is smooth and can be slick. Where the slab is and what happens on it should drive the choice before looks do.
Color, and how it ages
Integral color runs through the section so damage does not reveal gray concrete. Surface treatments give more depth and variation but live in the wear layer. Both change over years, and sealing is what holds them.
Joints inside a decorative layout
Control joints are structural and they still have to go where the slab needs them. On decorative work the layout is planned so joints fall in the pattern rather than cutting across it.
Sealing is ongoing
Decorative concrete is sealed and needs resealing periodically. That is genuine maintenance, and it is better to know it before choosing the finish than after.
What decides whether it lasts
Concrete is judged on the surface and it fails from underneath. The base, the steel, the joints and the cure are the whole job. A slab that was poured on bad ground will tell you so, usually in the third or fourth year.
Why fourth generation matters here
32 years on the tools means most of these problems have already been seen once. Reading a slab before quoting it is the part you cannot learn from a book, and it is the difference between a repair that holds and one that comes back.
What Southern California ground does to exposed aggregate concrete
Older flatwork around here
A lot of valley concrete was poured thin, with light reinforcement, on a base that was never properly compacted. When it fails it is usually reporting on the ground rather than on the mix, and that is the difference between a repair that holds and one that comes back in a year.
What lasts here
A properly based, properly jointed slab with reinforcement sized to the load will outlast the house it sits beside. The variables that decide it are all underneath and all invisible once the pour is done, which is exactly why they get cut on cheap jobs.
Drainage on a flat lot
Valley lots are often close to level, which makes slope hard to find and easy to get wrong. Low points, cross-fall and where water actually leaves the property get worked out before the pour, because once the concrete is down the drainage is permanent.
Summer pours
Triple digit afternoons change how concrete behaves. It stiffens before it can be finished properly, the surface skins over while the body underneath is still soft, and water leaves the slab faster than the cement can use it. Valley pours start early, the mix gets adjusted for the heat, and curing is treated as an active step instead of something that happens on its own.
How concrete fails, and why
Shrinkage cracks in the first month
Concrete gives up water as it cures and gets slightly smaller doing it. Where it cannot shrink freely it cracks. This is why joints exist, and why a slab with no joint plan cracks wherever it likes within the first few weeks.
Crazing on the surface
A fine map of hairlines across the top is usually a finishing and curing issue, not structural. Working the surface with water on it, or letting a slab dry too fast in wind, both produce it.
Edges breaking away
Corners and edges are the least supported concrete on any slab and the first to go. Thin edges, vehicles cutting corners, and no thickened perimeter all contribute.
Rust stains and cracks over the steel
When cracks run in straight lines that match the rebar spacing, the steel is corroding and expanding. That means water and chloride reached it, which is a cover problem.
How a job runs
Permits and inspection
Structural work and anything in the public right of way gets permitted and inspected. We raise that at the start rather than at the pour.
Utilities
Anything dug or cut starts with locating. Finding a line with a saw is expensive and avoidable.
Knowing when to start floating is the part you cannot learn from a book.On finishing
Noise and disruption
Breaking and cutting concrete is loud. We will tell you which days those are so you can plan around them.
Cleanup
Washout handled properly, spoil hauled off, surfaces washed. The site should look finished when we leave.
Other decorative work
Stamped Concrete
Texture pressed into the slab while it is still open.
Colored Concrete
Color through the mix or worked into the surface.
Broom-Finished Concrete
The working finish, done well.
Salt Finish Concrete
Rock salt pressed in, then washed out.
Sand Finish Concrete
A fine, even surface texture.
Polished Concrete
Grinding the slab itself to a finish.
Concrete Overlays
A thin new wearing surface, bonded down.
Epoxy-Ready Concrete Floors
A slab finished so a coating will actually bond.
Straight answers
Does decorative concrete need sealing?
Yes, and then again periodically. Sealing protects the finish and the color. It is maintenance rather than a one-time step.
Which finish should I pick?
It comes down to where it is and what it has to do. Broom and salt finishes grip when wet. Exposed aggregate hides wear. Stamped and colored work read best where people actually look at the floor.
Is stamped concrete slippery?
Texture usually helps rather than hurts. Around a pool we specify for slip resistance deliberately, because wet feet are the whole point of that slab.
Can you do decorative work on an existing slab?
If the slab is sound, an overlay or a polish can change the surface without demolition. Bonding is the whole question, which means the existing concrete has to be prepared properly.
Will color fade?
Integral color goes through the whole section so a chip does not show gray, and it holds up better than surface color. Anything on the surface is in the wear layer and will need maintenance.
