Rectangular flagstone for ground covering

摘要

The flagstone comprises a plate portion (D), to which a base (B) is glued, consisting of bedding (G) and reinforcing (C) layers. Perforated mounting bosses (1) on the reinforcing layer protrude beyond the plate periphery, being inclined to it all in the same direction. A self-adhesive coating is provided on the bedding layer, while the base is perforated in a sieve pattern. To allow for variations in the seam width (S), the bosses protrude for less than the intended width of the latter. Between the first two successive main axes (x,y) of the base of the bosses are longer. The top surfaces of the base and protrusions can be keyed.
