Cracks will develop within continuously reinforced slabs. This, however, will
not give rise to concerns provided they are neither too wide nor too close
together. Cracks should be no closer than 1.5m but no further apart than twice
this distance, as this would result in the cracks being at a width that would
require significant maintenance. There is a strong likelihood that cracks less than
1.5m apart will result in punching failure
