The message
from "hillier" contains these words:

My patio is made up with 2ft slabs on a dry mix of sand and cement. One of
the slabs has dropped slightly at one end.
Is there a way to lift and build up the slab without a major operation or
damaging the slabs.

Little pile of fine sand on the low bit. Lift carefully with the corner
of a spade, or similar. When level, wash sand into cracks with a small
watering can or similar.
