What are shallow setts?
Shallow setts are those having depth less than width.
Precast concrete setts have long been manufactured having shallow depth and it is now common to manufacture natural stone setts in this format.
Specifying shallow setts makes a more economical use of the raw material used in their manufacture but the pavement construction requires to designed more carefully and there is an upper limit to the level of traffic which can be carried.  British Standards BS7533-7 & BS7533-10 provide guidance for the specification of shallow setts.
