“Three years ago all the Girl’s ASA State Fast Pitch games were rained out due to poor field conditions. Caldwell’s State Championships were completed because of having Diamond Dust on the 4-plex fields”

Moisture Control, Drainage, Compaction, Traction, Play-ability, and Maintenance are the most critical elements in creating a superior infield. Diamond Dust 4in1 exceeds all infield play surface expectations.
Diamond Dust is a pure 100% pumice material. No silt, sand, clay or color additives. As a porous organic material, it naturally absorbs water and drains well. And it’s because of this unique porous property it retains perfect moisture for compaction and traction, but won’t become heavy, slick or pack down into a settled mass like sand/clay.
Unlike other infield baseball dirt material, Diamond Dust wicks moisture up and down evenly to maintain a premium safe consistency.

Comparisons to Most Typical Infield Products: Typically most infield products being sold in the U.S. are 2 to 3 times heavier than our 100% Pure Pumice products. They contain various combinations of sands (60% to 70%), while the other (30% to 40%), mainly consisting of an array of fine silts and various types of clay, cinders, decomposed granite, various coloring dyes and binding agents with an end goal of producing the perfect infield products. They have to blend all these materials so they will bind together in order to meet the 6 basic industry requirements; for Moisture Control, Drainage, Compaction, Traction, Play-Ability and Maintenance. Our 100% Pure Pumice products do this without the ill effects of using sand, silt, & clay.
