Wire mesh
Wire mesh is a grid of steel wires used to reinforce concrete slabs.
Why it matters
It can help control crack movement if it is placed correctly.
Where people get this wrong
Wire mesh only works when it is held in the right position in the slab. Mesh left flat on the ground is common and often ineffective.
Real-world example
A slab cracks and you can see the crack opening and closing with seasons. If reinforcement was in the right place, the crack movement can be smaller.
Where this hits your build
This matters during site work and foundation. Mistakes here get buried and are expensive to fix later. Pay attention before concrete is poured.
