Concrete Curbs and Gutters in San Antonio, TX
Curb and gutter is drainage infrastructure that happens to look like trim. If the flowline wanders, water pools in a parking lot and starts eating the asphalt edge and the pavement subgrade with it.

How San Antonio curbs & gutters are built, step by step
Curb and gutter is drainage infrastructure that happens to look like trim. Drag the timeline to see the full sequence — mark, excavate, compact, form, steel, pour, finish, and strip.
01 02 Excavate
Soil is removed along the curb-and-gutter path, creating a clean channel for the base and forms.
03 Grade & Compact
Aggregate base is placed in lifts and compacted to a firm, properly sloped bedding layer.
04 Set Forms
Vertical curb forms and the lower gutter channel are staked, braced, and checked to line.
05 Add Steel
Longitudinal rebar and dowels are positioned where the engineer's details call for reinforcement.
06 Pour Concrete
The curb and gutter are filled continuously so there are no cold joints in the flowline.
07 Shape & Finish
The curb face, gutter slope, edges, and control joints are formed before the concrete sets.
08 Strip & Reveal
Forms come off and the finished section is left moving water exactly where it should go.

Overview
Concrete Curb and Gutter Installation in San Antonio, TX
Curb and gutter looks like trim around a parking lot, but it's really drainage infrastructure. It defines where vehicles can go, holds the edge of the pavement together, and — most importantly — carries stormwater along a controlled path to an inlet instead of letting it spread across the lot and soak into the base.
We install and replace curb and gutter for commercial properties, retail centers, apartment complexes, HOAs, subdivisions and industrial sites throughout the San Antonio area. That includes standard barrier curb, rolled curb, integral curb and gutter, curb radii and islands, valley gutters, inlet transitions and drive approaches.
When curb work goes wrong, it usually shows up as water. A flowline that wanders even slightly leaves standing water in a parking lot, and that water works its way into the pavement edge and the base underneath it. Fixing pavement that's failing because of a bad curb line costs several times what the curb did.

Why It's Worth Doing Right
What Good Curb and Gutter Work Does for a Property
Controlled stormwater
A consistent flowline moves runoff to the inlets instead of letting it pond in drive lanes and parking stalls.
It protects the pavement
Curb holds the edge of asphalt in place. Without it, edges ravel and break down from the outside in.
Traffic control and site definition
Curb lines, islands and radii keep vehicles where they belong and keep them off landscaping and sidewalks.
Fewer pavement repairs later
Water that never gets into the base doesn't undermine it, which means far fewer potholes and edge repairs down the road.
A finished, maintained look
Straight, consistent curb lines and clean radii are one of the first things people notice about how a commercial property is kept up.
Safer pedestrian separation
Curb creates a defined line between vehicle areas and walkways, islands and building fronts.
Is This You?
When Curb and Gutter Needs Attention
- Water standing along the curb line or in the gutter pan after rain
- Broken, spalled or crumbling curb sections, especially at drive entrances
- Curb that has been hit and displaced by vehicles or equipment
- Asphalt edges raveling where curb is missing or has broken away
- New parking lot construction or a lot expansion
- A parking lot reconfiguration that changes drive lanes, islands or stall layout
- Subdivision or development work requiring new curb, gutter and approaches
- Damaged or settled inlet transitions and valley gutters
What to Expect
How Curb and Gutter Work Gets Done
01 Site review and grade check
We look at the existing flowline, inlet locations and how water currently moves across the site before pricing anything.
02 Written scope and phasing plan
For occupied properties, the estimate includes how the work gets phased so tenants and customers keep access during construction.
03 Removal of failed sections
Existing curb is saw-cut and removed to clean joints, with the adjacent pavement protected and cut back where required.
04 Subgrade prep and stringline
The base under the curb is prepared and compacted, and grades are shot and strung so the flowline runs continuously to the inlet.
05 Form or machine placement
Curb is formed or slip-formed depending on the run, then placed, consolidated and finished to a consistent profile.
06 Joints, backfill and cleanup
Joints are tooled, curb is backfilled behind so the edge is supported, and the site is swept clean before reopening the area.
Worth Knowing
Getting the Flowline Right Is the Whole Job
Curb profile is easy to get consistent. Flowline elevation is what takes attention. A gutter pan with a flat spot or a slight reverse grade will hold water permanently, and it doesn't take much — a fraction of an inch over a long run is enough to leave a puddle that never fully drains.
That's why grades get shot before placement and verified again after, especially through radii, at inlet transitions and where new curb ties into existing curb that was built to someone else's elevations. Tying into existing work is where most flowline problems get created.
Details that matter on a curb and gutter project:
- Continuous fall to the inlet, verified rather than eyeballed.
- Clean transitions where new curb meets existing curb, drive approaches and valley gutters.
- Curb profile consistency through radii and around islands.
- Backfill behind the curb so it's supported rather than left with an exposed back face.
- Phasing on active properties so drive access and fire lanes stay open.
Service Area
Curb and Gutter Work Across the San Antonio Metro
We work on commercial and residential development sites throughout San Antonio and the surrounding area, including Schertz, Cibolo, Converse, Universal City, Live Oak, Selma, Boerne, Helotes and New Braunfels.
Rain patterns here put curb work under real pressure. Long dry periods followed by intense rainfall mean a parking lot's drainage system has to handle a lot of water in a short window. Curb and gutter that only works in a light drizzle shows its problems the first time a heavy storm rolls through.
Public improvements and work in the right-of-way are typically subject to local standards and inspection. On projects that involve city or county requirements, we build to the specified detail and coordinate with the inspecting authority.
Questions
Curb and Gutter Questions
Can you replace only the damaged curb sections?
Yes. Failed sections are saw-cut out and replaced, tying into the existing curb at both ends. We check the flowline through the replacement so the new section doesn't create a low spot.
What's the difference between barrier curb and rolled curb?
Barrier curb has a vertical face that discourages vehicles from crossing it. Rolled curb has a sloped face vehicles can drive over, which is common at residential driveways. Which one you need depends on the site and any applicable standards.
How long does a parking lot need to stay closed?
Usually only the section being worked on. We phase curb work so most of the lot stays open, and we give you a specific schedule for when the poured sections can carry traffic again.
Why does water stand in my gutter pan?
Almost always a flowline problem — either the curb was placed without continuous fall to the inlet, or a section has settled. Correcting it means removing and re-placing the affected run to the right elevation.
Do you do drive approaches and valley gutters too?
Yes. Approaches, valley gutters, inlet transitions, islands and radii are all part of standard curb and gutter work, and they're the spots where getting the transition right matters most.
Can you match the profile of the existing curb on my property?
In most cases yes. We measure the existing profile on site so replacement sections line up with what stays instead of standing out.
