Rebar vs. Wire Mesh: Concrete Reinforcement

Reinforcement does not stop cracks; it manages them. Choosing between rebar and welded wire mesh depends on the project, load, and expected use.

Wire Mesh

Welded wire mesh provides crack control across relatively lightly loaded slabs. It must be positioned in the correct plane during the pour to be effective.

Rebar

Rebar offers greater tensile strength, useful for driveways with heavier vehicles, thicker slabs, and projects where load and span justify it.

How Decisions Are Made

  • Expected use and load
  • Slab thickness and span
  • Soil and base stability
  • Project specifications when applicable

Frequently Asked Questions

Do all concrete slabs need reinforcement?+

Most exterior slabs benefit from reinforcement. The type and layout depend on load, span, and use.

Does rebar or mesh prevent cracking?+

Reinforcement does not prevent cracks. It controls where and how much cracks open once they form.
