I have an area that I am going to slab with different sizes of slabs.
It is only to be used as a patio, with no heavy traffic. I am being told different advice, as to what sub base to use, if any.
Some say just compact the soil, and add a thin layer of sand to level the site, then dabs of mortar to bed the slabs.
Others say dig down 6 ins, apply hardcore, then compact, layer of sharp sand to level, then dabs of mortor to bed the slabs.
Just what can I get away with ??? but to do a decent job.
