Premium Superior Quality Bunker Sand using Specialty Minerals Bunker-White® Ground Calcium Carbonate

Bunkers are a concern for golf course architects, superintendents, and players alike. Ensuring the best quality and playability of sand traps, thus resulting in a fair hazard, requires superior sand quality. The USGA considers numerous factors when selecting bunker sand: particle size, particle shape, crusting potential, infiltration rate, penetrometer value, chemical reaction and hardness, and overall playing quality. When you add aesthetics to the mix, high-brightness limestone stands out as the premium choice among course architects and superintendents, replacing darker silica sands.
