Concrete Reinforcing Mesh: Everything You Need To Know.
When it is poured, concrete is incredibly strong under compression (withstanding heavy downward weight). However, it is naturally weak under tension (pulling or stretching forces).
As concrete cures, it naturally shrinks, which can lead to unsightly cracks. Changes in temperature and shifting ground underneath the slab add further stress.
That is where steel reinforcing mesh (or fabric) comes in. By embedding steel mesh into your concrete, you give the slab high tensile strength. This holds the concrete together, prevents major cracking, and ensures your project lasts for decades.

Why Use Concrete Reinforcing Mesh?
- Prevents Cracking: Minimises shrinkage cracks during the drying process.
- Increases Load Capacity: Distributes heavy weight evenly across the slab.
- Extends Lifespan: Protects your investment from ground movement and seasonal freeze-thaw cycles.
Choosing The Right Reinforcing Mesh: A142 vs. A393
| Specification | A142 Mesh | A393 Mesh |
| Wire Thickness | 6mm | 10mm |
| Mesh Grid Size | 200mm x 200mm | 200mm x 200mm |
| Best Used For | Light-duty & domestic projects | Heavy-duty & commercial projects |
| Typical Applications | Driveways, garden paths, patio slabs, garage floors | Commercial yards, heavy vehicle parking, industrial floors |
A142 Reinforcing Mesh (6mm Wire)
This is the go-to standard for most domestic projects. If you are pouring a standard garden patio, a residential driveway, or a base for a shed or garage, A142 provides the perfect balance of strength and manageability.
A393 Reinforcing Mesh (10mm Wire)
Engineered for heavy-duty applications. The much thicker 10mm steel wires are designed to withstand significant weight and high-traffic stress. If your slab will be hosting heavy commercial vehicles, industrial machinery, or needs to meet strict structural engineering specs, A393 is the definitive choice.
