Concrete Reinforcing Bar (Rebar) Installation Sizes

The installation of the rebar is critical for the success of the overall project. Rebar should be placed evenly throughout the project. For a flat slab, such as a driveway, consider placing the rebar in an 18 inch grid spacing, keeping the edge rebar at the same distance from each side. For a patio you can use a grid spacing of 24 inches.

Rebar vs Wiremesh Spacing for Slab - Fine Homebuilding

Jan 21, 2006  My understanding of slabs based on limited experience and a heck of a lot of reading here is:1. The compaction UNDER the slab is more important than the thickness of the slab. 2. Wire mesh is better then rebar, if it can be kept up off the bottom of the slab. 3. Rebar only serves to limit the width of cracks AFTER the concrete cracks.
