There are lots of posts about this but none seem to explain the benefits of either method.
I was planning on laying a new patio (38mm thick concrete slab paving) on 100mm of MOT compacted hardcore and 40mm of compacted sharp sand.
However several posts say to use just the MOT and bed the flags on a wet mix of sand and cement? Is this a better method?
Our ground is clay.
