The CalTrax IMB® (Impermeable Mat/Broadcast) is a 100% polyurethane-based track system that offers exceptional all-weather performance and spike resistance. The paved-in-place base layer provides exceptional shock absorption allowing safer long-term training. The two-component polyurethane sealer layer makes this system impermeable and adds increased resilience and durability. Finally, the micro-embedded broadcast EPDM finish provides the highly textured and durable wearing layer. The finished track system is a smooth, virtually seamless surface with outstanding performance characteristics and durability. California Track uses only time-tested polyurethane manufactured by Advanced Polymer Technology, Inc.

The CalTrax IMB polyurethane is made in the USA from materials free of mercury and other heavy metals by design.
