Concrete Slab Calculator
Estimate concrete cubic yards, slab area, base gravel, rebar or mesh, formwork and material cost for a slab-on-grade project.
Estimate concrete for a slab
Estimate slab materials from length, width, thickness, cubic yards, base material, reinforcement and cost. Use the result for planning quantities before confirming slab design, joints, base preparation and local requirements.
Ordering and design notes
- Base thickness, compaction, vapor barrier, insulation, joints, reinforcement and curing affect slab performance.
- Driveways, garages, patios and structural slabs can require different concrete strength and detailing.
- Use supplier yield, local code and project drawings before ordering ready-mix or bagged concrete.
