Hanger floors can be subjected to extreme severity of use in the form of heavy point loadings and regular spillage of grease and oil. This can give rise to serious damage to normal asphalt surfacings and these are therefore not recommended for this type of flooring. Special proprietary materials, e.g., epoxy asphalt or sand/cement/polymer grouted asphalts, or alternative forms of construction such as concrete, will be more appropriate in such circumstances.
