ABSTRACT:
A flexible shock absorbing component providing cushioning for surfaces, especially wall and floor surfaces, is described. The shock absorbing component includes two sheets of thermoplastic, each sheet with inwardly facing, opposing, resiliently compressible indentations extending into a cavity between the two sheets. The shock absorbing component also includes a layer of particulate matter applied to and adhered to the outer surface of one of the sheets, to provide wear and weather resistance. A moderator may also be attached to the outer surface of the sheet.
