Concrete Monolithic Slab Cost Calculator
To provide a rough estimate of the cost for a concrete monolithic slab, we can break down the table into key factors that impact pricing, including material costs, labor, and additional features. Below is an example table that reflects the approximate costs for a 1,000 sq. ft. slab (standard size for a small home foundation) based on average prices.
| Cost Category | Cost per Unit | Total Cost (for 1,000 sq. ft.) |
|---|---|---|
| 1. Concrete (Material) | $4 – $8 per sq. ft. | $4,000 – $8,000 |
| 2. Labor (Pouring, Finishing) | $2 – $3 per sq. ft. | $2,000 – $3,000 |
| 3. Excavation and Grading | $500 – $2,000 | $500 – $2,000 |
| 4. Rebar or Wire Mesh | $0.50 – $2 per sq. ft. | $500 – $2,000 |
| 5. Vapor Barrier | $0.30 – $0.60 per sq. ft. | $300 – $600 |
| 6. Footing (for monolithic slab) | $3 – $5 per linear ft. (perimeter) | $1,200 – $2,000 (for a 40×25 slab) |
| 7. Insulation (Optional) | $1 – $3 per sq. ft. | $1,000 – $3,000 |
| 8. Permit and Inspection Fees | $500 – $1,500 | $500 – $1,500 |
| 9. Additional Features (e.g., thicker slab, colored/stamped finish) | Varies | $500 – $2,000 |
Total Estimated Cost
- Low-end: $9,000
- High-end: $22,000+
Key Factors Affecting Cost:
- Concrete Thickness: Standard thickness is 4-6 inches, but for heavy loads, it may need to be thicker.
- Site Preparation: If the site requires significant excavation or grading, this can increase costs.
- Location: Prices for materials and labor vary by region.
- Reinforcements: Adding rebar or wire mesh for additional strength will increase cost.
- Footing Depth: Monolithic slabs require thicker footing around the perimeter, especially in cold climates.
- Finishing Touches: Custom finishes (like stamped, colored concrete) add aesthetic value and increase cost.
