Welded wire mesh Welded wire mesh is a grid of steel wires welded together at regular intervals and used to reinforce concrete. It helps distribute loads and limit the width of shrinkage cracks.
Welded wire mesh is supplied in sheets or rolls and is positioned within the concrete before placement. It provides more uniform reinforcement than individual loose wires and is commonly used where engineered plans call for crack control. Proper placement is important so the mesh remains at the intended depth within the slab.
Frequently Asked Questions About Welded wire mesh
What is welded wire mesh?
A grid of steel wires welded at regular intervals, placed within concrete to distribute loads and limit the width of shrinkage cracks.
How is it different from rebar?
Mesh provides light, distributed crack control across a slab. Rebar provides heavier, engineered structural reinforcement.
Why does positioning matter?
Mesh must sit at the intended depth within the slab. Mesh left lying on the base does almost nothing for crack control.
Is mesh required in sidewalks?
Only where engineered plans call for it. Many standard sidewalk flags rely on proper jointing and base preparation instead.
