Slab Thickness Calculator
Calculate the optimal concrete slab thickness for your construction project. Determine concrete volume, reinforcement needs, and cost estimates based on load requirements and soil conditions.
Step 1: Project Dimensions
Thickness Guidelines
Standard residential slabs: 4-6 inches. Driveways: 5-6 inches. Heavy loads: 6-8+ inches. Commercial: 8-12+ inches. Always consult local building codes.
Step 2: Material & Cost
About Reinforcement
Reinforcement controls cracking and increases strength. Wire mesh is common for residential slabs. Rebar provides maximum strength for heavy loads. Fiber reinforcement helps prevent plastic shrinkage cracks.

Slab Calculation Formula
Volume (cubic yards) = (Length × Width × (Thickness/12)) / 27
To calculate concrete volume: Multiply length (ft) × width (ft) × thickness (ft), then divide by 27 to convert to cubic yards. Add 5-10% for waste.
