True or False: Welded wire mesh is often used as reinforcing in concrete slabs.

• A. False
• B. Sometimes
• C. True
• D. Not sure

Answer: (C)

Welded wire mesh provides a uniform grid of reinforcement that helps resist cracking and distribute forces across a concrete slab. This type of mesh is commonly used in many typical slab applications because it’s quick to install, covers large areas evenly, and is cost-effective for light- to medium-duty slabs such as sidewalks, driveways, and garage floors. While heavier structural slabs may call for larger or additional reinforcement (like deformed rebar), welded wire mesh is indeed often used as the reinforcing in concrete slabs.
