I have some "stepping stones" set in to my lawn: 9x18 cms and also a
couple of paving slabs : 60x75 cms which have sunk.
Is it better to relay them on "blobs" of cement rather than just
trying to get a sand base nice and level. I am think if large blobs
of cement are used it will be easier to get them level by tapping them
down with a rubber mallet. (The paving slabs take no vehicles)
