How much could we reduce the thickness of an unreinforced concrete driveway if we include wire mesh in its construction?
Don't try. The standard purpose of using welded wire fabric, commonly known as wire mesh, in driveways or other flatwork is not to contribute to its strength. It is intended to hold together any cracks that might form in the slab. The amount normally used does not materially affect the flexural strength. To increase the flexural strength would require a considerably larger amount and the fabric would have to be positioned at both the top and bottom of the slab since the location of tensile stresses varies from top to bottom as loads move over soft and hard spots in the subgrade.
