Hi Folks, I'm in the process of boxing up a slab area for a 10 x 4m carport and I have Googled the question and it recommends 65mm for the height of the reinforcing mesh.
The slab is to be 100mm thick and I'm getting 25mpa concrete and having the mesh at 65mm is that okay to prevent cracking.
The carport is to house a Ford RTV trayback.
