• Thickness = Selected slab thickness (in meters)
• Concrete Cost per Cubic Meter = Based on concrete type
• Labor Cost per Square Meter = Based on labor rate category

Factors Affecting Concrete Slab Cost

Several factors influence the cost of a concrete slab in Ontario:

1. Size and Shape: Larger slabs require more materials and labor
2. Thickness: Thicker slabs cost more due to increased material requirements
3. Concrete Type: Different concrete mixes have varying costs
4. Labor Rates: Local labor costs affect the final price
5. Location: Some areas may have higher material or labor costs
6. Additional Features: Reinforcement, finishes, or special requirements add to the cost

Worked Example

Let's calculate the cost for a 5m × 6m concrete slab with 10cm thickness using standard concrete and average labor rates:

This example shows that for a standard 5m × 6m slab with 10cm thickness, the estimated cost would be approximately $1,860 in Ontario.
