Why Should Wiremesh Be Installed Before Casting?

In concrete structural work, especially on floors, roofs, or roads, wire mesh is an essential element. But why must it be installed before the pouring process?

The answer is directly related to the structural function and long-term strength of the concrete itself. Here's a complete explanation.

What is Wire Mesh?
Wire mesh is a woven steel wire mesh in the form of sheets or rolls, usually available in various sizes and diameters. Its function is to reinforce the concrete so that it doesn't crack or break easily when subjected to loads.

Reasons for Installing Wire Mesh Before Pouring
1. Reinforcing Concrete from Within
Concrete is very strong in compression, but weak in tension. This is where wire mesh comes into play as reinforcement, helping to withstand tensile forces and prevent cracks that occur due to dynamic loads or temperature changes.

2. Reducing Hairline Cracks
Fine cracks (hairline cracks) often appear if concrete is not reinforced from the start. Wire mesh helps distribute stress evenly, making the concrete more stable and less prone to cracking.

3. Increase Floor Bearing Capacity
On concrete floors—whether on a house roof, garage, or warehouse floor—wire mesh helps make the structure more rigid and able to withstand heavy loads without sagging.

4. Work Efficiency
Installing wire mesh before pouring is very practical because it's already assembled. The worker simply adjusts the position and height using concrete wedges (dobeg), without having to tie the steel bars individually like manual reinforcement.

What Happens If Installed After Pouring?
Installing wire mesh after the concrete has been poured will not have any structural effect, as its function is to bond with the concrete mix. If installed on a hardened surface, the wire mesh will only serve as a complementary layer without affecting the concrete's strength.
