Wire mesh under saw cut joint

[Okiryu]

I have a slab on grade, 6 and 8 inches thick. No vehicle loading, just well distributed load (liquid). Saw cut is 40 mm depth and wire mesh is 50 mm below the surface of the slab. Do I needs to cut the wire mesh under the saw cut joints or can the wire mesh be continuous thru the slab. Joints are at 5 m spacing.

BTW, joints will be sealed

It is typical to cut every second bar of the mesh perpendicular to the saw cut or cut out every second bar (one grid only, ie. the bar that is cut in the first option) at the location of the proposed saw cut joint to reduce the strength and help propagate cracking at the the desired location.

Thanks for the response. I was checking further and looks like we will need to cut the mesh under the saw cut joint as ShawThing has indicated above. Thanks again!
