Surface regularity – levelness and flatness

Surface regularity, as defined in terms of levelness and flatness of an unformed ground or
suspended slab surface is important to satisfactorily apply flooring materials or, in the
case of a wearing surface, for traffic and people to circulate safely. The slab must also be
constructed within a tolerance of a datum plane. Over specification of tolerances can lead
to unwarranted costs and require a particular approach to the finishing process.
