Kafka Granite

Kafka Granite is a Wisconsin-based aggregate manufacturer specializing in decomposed granite and infield mix products for baseball and softball facilities. Their materials are used on infields and warning tracks, two areas where surface consistency, drainage, and long-term stability directly affect player safety and field playability. Decomposed granite is a popular choice for warning tracks because its distinct texture and firm footing give outfielders a reliable tactile cue as they approach the wall. For infields, aggregate composition, particle size, and binder type all influence how a surface handles moisture, compaction, and cleat wear over a season.

Kafka Granite offers their decomposed granite materials in standard, stabilized, and wax-polymer formulations. The stabilized option uses an organic binder to reduce dust and improve cohesion, while the wax-polymer version provides an alternative approach to surface binding and moisture management. Products are shipped nationally, making them accessible to facilities well beyond the Upper Midwest. See the contact and location details on this page to reach Kafka Granite directly.
