ABSTRACT OF THE DISCLOSURE The invention relates to a wall or an earth sustaining wall. Elements to be joined to each other by means of tongue- and-groove elements, shaped in their horizontal section like part of an approximately regular figure (i.e. congruent with it- self after rotation through a given angle a) are assembled, course by course, to form a wall. The tongue-and-groove joints of the elements are intercalated course by course on opposite sides of certain vertical lines so that the centres of the regular figures of the tongues and grooves lie on straight lines. The wall corners are formed by changing the direction of the elements by rotating a basic component of the regular figure recurring in the tongue-and-groove (e.g. the side of a polygon) through the central angle of the figure or a multiple thereof.
