What size mesh do I need for concrete?
The most common size is 150x150mm with a 4mm thickness. A reinforcing mesh is set inside the concrete during construction. After the slab is set, the mesh inside it offers additional strength against pressure. Thus, concrete with reinforcing mesh is able to withstand much more pressure than regular concrete slabs.
Do I need plastic under concrete?
A concrete vapor barrier is any material that prevents moisture from entering a concrete slab. Vapor barriers are used because while fresh concrete is poured wet, it’s not supposed to stay that way. It needs to dry and then stay dry to avoid flooring problems. This is why a vapor barrier under concrete is essential.
Do you need wire mesh for 4 inch slab?
No, they do not. Larger projects or slabs may need steel reinforcement to provide support or extra strength. Wired mesh can also help resist breaking. However, not every piece of concrete necessarily requires that extra boost.
