ABSTRACT:
A tactile warning pad composed of a polymer material, the pad comprising contact structures on its upper surface and embedded shearable anchor members in the form of a corrugated mesh webbing, wherein the upper portions of the mesh webbing are embedded within the pad and the lower portions of the mesh webbing extend below the pad, such that the pad may be positioned atop an uncured concrete base with the lower portions of the mesh webbing embedded within the concrete, and further such that the anchor members retain the pad on the concrete base once the concrete has hardened, and further such that the pad is removable from the concrete by shearing the anchor members at the interface between the concrete base and the polymer pad using a bladed shearing implement.
