The edging 1 comprises a tactile unit 5 let into the upper surface of a coping stone 2 used for edging. The edging is particularly used for raised platforms such as railway platforms or roadside kerb pavements. The edging preferably is in the form of a block, lamina or slab with a recess, indentation or rebate 7 which receives the tactile unit. The tactile unit is preferably thin relative to the coping stone such that the thickness of the stone below the unit is 85% of the overall thickness of the stone. The product allows easier access to those with visual impairments by having a tactile, relieved, studded or ridged surface near the edge of a road or platform, additionally the tactile unit can be made from material which is of a contrasting colour to the coping stone for easier visibility and acting as a warning. The tactile unit may have protrusions which are integral to it or have integers such as bosses, studs or domes attached to it. |
