ABSTRACT:
Wheel chock blocks may be comprised of bodies of various ultra-lightweight foam materials, such as expanded polystyrene. A coating may be provided which integrally covers such bodies to form a skin effect for dispersing pressures applied thereto over such body. Thus, effective use is made of the entire compressive strength of the block, which further permits practical use of even such ultra-lightweight materials. Such coating may be formed with hardened latex paint, which paint also slightly penetrates the foam body so as to further enhance the skin effect thereof.
