An erosion resistant composition includes a granular material and a wax including oil in which a weight percent of the oil in the wax is between 0.01-15%. The granular material includes a sand and has a first resistance to flow prior to being coated with the wax. The wax at least partially coats a portion of the granular material to form the erosion resistant composition which has a second resistance to flow after coating that is greater than the first resistance to flow prior to coating. The erosion resistant composition may be used, for example, in golf course bunkers or other landscaping applications. Related methods of making the erosion resistant composition are also described in which the granular material is dried, the wax is heated, and the granular material is blended with the melted wax.
