New Construction
Concrete Curbs & Sidewalks in Arizona
Curb, gutter, valley pan, commercial sidewalk, and trip-hazard repair for parking lots, HOA streets, and municipal frontage across Arizona, self-performed by in-house crews and backed by a 2-year workmanship warranty.
THE EDGE THAT HOLDS THE LOT
Curb is not trim. It confines the asphalt, holds compaction at the perimeter, and carries stormwater to the inlets. When curb breaks down, the pavement next to it ravels and the base starts taking water, which is how a maintenance item turns into a reconstruction bill. American Asphalt has been building and repairing curb, gutter, and sidewalk on Arizona commercial property for more than 30 years.
Curb and walkway work is part of our full commercial concrete services, sequenced ahead of asphalt paving so the mat ties in flush, and coordinated with ADA ramp and accessible access work wherever the walkway carries an accessible route.

CONTROL WATER, PROTECT PAVING
Sound curb and correctly sloped walkways keep water moving, keep the asphalt edge confined, and keep pedestrians on a safe, compliant surface, three of the biggest drivers of pavement life and liability on a commercial site.
Protects the asphalt edge
Unsupported asphalt edges ravel and crumble first. Sound curb confines the pavement, holds compaction at the perimeter, and dramatically extends the life of the lot.
Controls water, the real enemy
Curb, gutter, and valley pans move runoff to inlets. Water that sits on or under asphalt is what causes alligator cracking and base failure in Arizona lots.
Removes trip-hazard liability
Heaved and settled sidewalk panels are among the most common slip-and-fall claims on commercial property. Replacement is cheap compared to the exposure.
Keeps accessible routes compliant
Sidewalk cross-slope, width, and surface condition are part of ADA compliance, not just aesthetics. We build and verify walkways against current tolerances.
Sequenced with your paving
Curb and walk are poured, cured, and ready before asphalt is placed against them, so the two surfaces meet flush with no lip, gap, or drainage trap.
Backed for two years
All curb, gutter, and sidewalk work carries a 2-year workmanship warranty from a family-owned Arizona contractor operating since 1993.

CURB & SIDEWALK SCOPES
Vertical and roll curb, curb and gutter, commercial sidewalks, valley pans, trip-hazard removal, and curb replacement with asphalt tie-in, all self-performed.
SHOOT GRADES, FORM, POUR & TIE IN
Curb and sidewalk live or die on grade and compaction. We establish flow lines before forming, compact the subgrade to density, and cut joints on schedule so the concrete cracks where we tell it to instead of where it wants to.

- 01Step
Grade survey & layout
We shoot existing elevations, establish flow lines and top-of-curb grades, and stake the alignment so drainage is designed before anything is formed.
- 02Step
Demo, excavate & compact
Failed curb or panels are sawcut and removed, subgrade is excavated to depth, and base is moisture-conditioned and compacted to the required density.
- 03Step
Form, reinforce & place
Forms set to string line or curb machine run to grade, dowels and reinforcement placed where specified, then concrete placed, consolidated, and finished.
- 04Step
Joint, cure & tie in
Control and expansion joints cut on schedule, curing applied and protected, then asphalt or landscape is tied in flush against the new concrete edge.

Every foot of curb, gutter, and sidewalk we place is built to a published material and workmanship standard. Below are the specifications and credentials most commonly referenced on the commercial, HOA, and public-agency flatwork we perform.
