If they don't, then 4 thick is usually standard for a patio slab, how large or small it is doesn't really matter. The most important part is the sub-base. Make sure you have a good gravel base. I would recommend at least 12 inches of compacted gravel. I like gravel where the aggregate (rocks) are no larger than 1.
How thick for a concrete patio base? This will be done with a rough finish to install a flagstone patio (mortar bed) on top. Total size will be around 14&#39;x24&#39;. I&#39;m thinking about 4&quot; . . . but am also curious about reinforcing steel and expansion joint needs.
