When selecting bunker sand for your course, perhaps nothing matters more than purity, but non-manufactured and unwashed sands can contain nematodes, clay and other potentially hazardous items. Calcium Products' bunker sands come from one of the purest limestone mines in the nation. Our sands are also superior in the vital areas of color, size, shape, and playability. Our color rating is white when dry and very pale brown when wet, giving your course that 'wow' factor. Our particle size is ideal for water infiltration, resulting in far-better drainage after rain events. Our sands are naturally-derived, not rounded, so they won't blow or drift away. Playability is also a key factor, and our bunker sand has consistently high ratings for avoiding fried-egg lies and buried balls, providing ideal conditions for the amateur golfer.
