Driveways & RV pads
Vehicle loads plus irrigation and monsoon moisture. GFRP keeps cracks tight without rust-jacking the surface off years later.
Flatwork · Driveways · Patios · Slabs on grade
Rust is why driveways crack wide and slabs spall: steel and wire mesh corrode inside the concrete and push it apart. Pultrax GFRP rebar can't rust — your flatwork lasts as long as the concrete itself, and your crew installs it faster with tools they already own.
Where it works
Vehicle loads plus irrigation and monsoon moisture. GFRP keeps cracks tight without rust-jacking the surface off years later.
No rust bleed-through staining decorative or stamped finishes. The reinforcement never shows through the surface.
Full-strength reinforcement that doesn't corrode at cold joints and cracks — where steel always fails first.
Public flatwork with a 100-year design life. Lighter bars mean faster layout on long runs.
Slab-on-grade foundations with reinforcement rated for the life of the home, engineered per ACI 440.11-22.
Non-conductive and non-magnetic — ideal around pumps, transformers, and sensitive equipment.
Side by side
| Factor | Pultrax GFRP #3 | Welded wire mesh | Steel #3 bar |
|---|---|---|---|
| Corrosion / rust staining | Never | Rusts at every crack | Rusts, spalls surface |
| Stays in position mid-slab | Yes — rigid bar on chairs | Walked to the bottom | Yes |
| Weight to carry | 2.2 lb / 20 ft bar | Heavy, awkward sheets | 7.5 lb / 20 ft bar |
| Cutting | Grinder, ~5 sec | Bolt cutters | Rebar cutter / torch |
| Effective service life | 100+ years | 15–25 years | 25–40 years |
| Cost per square foot | Comparable* | Lower upfront, fails first | Comparable |
* Estimates for comparison; confirmed at quote. GFRP layout follows your engineer's design or ACI 440.11-22 — for typical residential slabs it replaces #3 steel one-for-one on the same spacing.
Desert slabs face brutal thermal cycling, alkaline caliche soils, and irrigation moisture. GFRP is chemically inert and has a thermal expansion close to concrete's — no internal rust pressure, no surprises ten summers in.
GFRP is commonly accepted for residential flatwork and slab-on-grade under the IRC — check with your building department. Permitted structural work is designed by a licensed engineer under ACI 440.11-22 with ASTM D7957 material data.
Federally funded flatwork increasingly requires Build America, Buy America–compliant materials — and imported bar is disqualified. Pultrax's all-American chain (SC glass, US resin, Arizona pultrusion) supports BABA compliance, with origin documentation on every lot. How the supply chain qualifies →
Installation
Same chairs, same grid you'd use with steel — typically every 3–4 ft so bars stay mid-slab. Bars this light won't crush chairs or sag between them.
Zip ties instead of wire twists — about 30 seconds a joint faster, no tie wire injuries, no rust spots at every tie.
Trim with an angle grinder wearing a dust mask. Then pour, screed, and finish exactly like any slab. Walking on GFRP won't displace it.
