Mortar Bedding
Slabs can be 'spot-bedded' with a small mound of mortar at each corner and one in
the middle; whilst this is easier to adjust and correct than other types of bedding
it is also weaker.
A full mortar bed provides the strongest support but can make it difficult to get
the slabs true and level.
Box and Cross bedding is a good compromise; providing good support while allowing
the mortar to squeeze sideways during levelling.
