Is it necessary to use spacers for determining the spacing between the individual welded wire meshes?

The use of spacers for determining the spacing between welded wire meshes is recommended since spacers secure the correct placement of reinforcement in concrete. Spacers are used to ensure that welded wire mesh stays at the correct height and distance, which guarantees an even load distribution and maximum strength of the concrete. As a matter of fact, spacers are also necessary in structures where welded wire mesh is used.
