ABSTRACT A novel paving slab, particularly for use outdoors or in areas where efficient drainage of water from the pavement surface is required. The slab comprises a composite of upper and lower superimposed layers bonded together, the upper layer being water-permeable and comprising a granular dispersion in a bonding medium and the lower layer comprising a closed- cellular, soft-foamed plastic material having a plurality of openings distributed therethrough. This arrangement overcomes the disadvantages of prior art structures that water inadequately drains from the paving surface and becomes trapped in the pores of the material.
