Concrete Slab Pricing Guide
Slab concrete is commonly used for driveways, patios, and foundations. Standard residential slabs typically use 3000-4000 PSI concrete for adequate strength and durability.
Key Pricing Factors:
- Slab thickness and reinforcement requirements
- Ground preparation and gravel base costs
- Finishing options (smooth, broom, or stamped)
- Vapor barriers and insulation needs
For current pricing in your area, contact local suppliers or visit Concrete.org.
