Sandwich Track System
IAAF-Compliant • High Strength • Long Service Life
Sandwich Track System
Our Sandwich Track System — a hybrid polyurethane solution — is built with a fully-poured, solid polyurethane base and a seamless PU or EPDM wear layer.
This system achieves consistent, competition-level performance, combining excellent energy restitution, cushioning, and shock absorption.
Complying with World Athletics (formerly IAAF) standards, it ensures long-term stability, outstanding spike resistance, and durability under heavy use.
It’s the ideal surface for high-frequency athletic environments, such as schools, universities, and professional stadiums.
