Abstract (en)
[origin: WO2018143808A1] A drainage block for dikes or urban settings and for use as a road pavement is provided with drainage and water buffering properties. The drainage blocks may be used in urban areas as pavement, or fundament or substructure underneath a street layer with porous / water passing pavement stones or clinkers with drainage and water buffering properties. The drainage blocks comprise four lateral faces, a base, and a single stem connecting the slab and the base, which stem has a cross-sectional area that is smaller than the cross-sectional areas of the slab and the base, thereby forming a water buffering space between the slab and the base; and wherein each of the four lateral faces of the slab comprises a single spacing projection.
