ABSTRACT:
The side surfaces of compound stones are provided with relatively flat elements which interlock with little play when said stones are laid out, while adjoining side surfaces of neighboring stones are in contact along two lines only. A compromise between a sufficient mutual securement of the stones and a certain mutual mobility thereof is thus obtained. In particular, a certain tilting of neighboring stones with respect to each other is possible, whereby it is possible to produce pavements in uneven places.
