Types of Concrete Work

Slab-on-Grade

Garage floors, basements, driveways. Typically 4-6" thick.

Footings & Foundations

Load-bearing foundations. 8-12" thick, often with rebar.

Walls & Retaining Walls

Structural walls requiring forms and reinforcement.

Patios & Walkways

Decorative concrete work. 4-5" thick with control joints.

Concrete Calculation Factors

Fresh vs. Hardened Concrete

Fresh concrete density:2,400 lbs/cubic yard
Hardened concrete density:2,500-2,600 lbs/cubic yard
Typical waste factor:5-10%

Pro Tip

Order concrete in full yard increments. Ready-mix trucks deliver in 1-yard batches.
