Paving stone unit having integral connecting webs

摘要

A concrete paving stone unit formed of a number of individual spaced paving stones connected together by integral thin webs. The webs constitute predetermined breaking points in the unit, so that when the unit is laid in sand and vibrated, some of the webs can break to allow the individual stones to bed firmly in the sand. If the ground shifts at a later date, other webs may break to allow the stones to conform to the new ground contour.
