Concrete driveway pours in Texas face extreme thermal contraction and aggressive subgrade soil movement. Proper mix design, steel reinforcement, and joint layout prevent early cracking and structural settlement.
Concrete Driveway Specifications by Application
| Application Type | Slab Thickness | Concrete Mix PSI | Reinforcement Spec | Cost / Sq Ft |
|---|---|---|---|---|
| Standard Residential | 4 Inches | 3,000 – 3,500 PSI | #3 Rebar on 18" centers | $8.50 – $11.00 |
| Heavy Duty / Truck / RV | 5 – 6 Inches | 4,000 PSI | #4 Rebar on 12" centers | $11.50 – $15.00 |
| Commercial Apron / Entry | 6 – 8 Inches | 4,000 – 4,500 PSI | #4 Rebar mat on 12" centers | $14.00 – $19.50 |
| Stamped Decorative Finish | 4 Inches | 3,500 – 4,000 PSI | #3 Rebar + Poly fiber mesh | $14.50 – $22.00 |
Critical Subgrade & Joint Guidelines
- Crushed stone base: Never pour directly on raw black gumbo clay. Lay a compacted 2 to 4-inch crushed road-base (crushed limestone or flex-base) foundation.
- Expansion joints: Place 1/2-inch expansion joint material against building foundations, garages, and municipal sidewalk tie-ins.
- Control joint depth: Saw-cut control joints must penetrate at least 1/4 the slab depth (1 inch deep on a 4-inch pour) within 12 to 24 hours of pouring.
