Wide bay pours are a
compromise between the advantages of long strip and large pours construction
In practice, a greater
degree of control is achieved on the floor flatness to allow a reduced level of
remedial grinding to achieve a Defined Movement flatness classification than if
the large pour method was adopted. The
wide bay method allows this with less significant loss of speed or overall
output when laying the slab, which is normally the case when employing the long
strip method of construction.
The bays can either be jointed or jointless, depending on how the floor
is supported and what it is reinforced with. Both types have formed joints
between bays but jointed bays also have a grid of induced joints running
through the bay.
