Competitive Price 13mm Compound Athletic Track Material

Excellent question. A composite track features a dual-layer structure: Base layer (9-10mm): Porous rubber granules bound with PU adhesive, providing shock absorption and allowing vapor release. Top layer (3-4mm): Dense, fine EPDM granules mixed with high-strength PU, forming a wear-resistant, spike-proof surface.

We recommend a stable asphalt or concrete base with a thickness of at least 80-100mm, properly compacted and cured. The base should have a slight slope (0.5%-1%) for drainage and must be clean, dry (moisture content <5%), and free from oil or loose particles. A primer coat is essential to ensure optimal adhesion between the base and the rubber layer.

Yes. When installed on a proper sub-base, our 13mm composite track meets World Athletics (IAAF) performance requirements for impact absorption (35-50%), vertical deformation (0.6-2.5mm), and skid resistance. It is suitable for official competitions, professional training, and educational institutions.

deal installation conditions are 5 to 35 degrees with relative humidity below 80%. Avoid installation during rain, heavy fog, or strong winds. The surface typically cures within 24-48 hours, and the track can be fully opened for use after 7 days of proper curing. For cold climates, we recommend using winter-grade adhesive to extend the working time.

The porous base layer allows water to drain quickly through the system, while the dense top layer prevents water from penetrating deeper. This hybrid design ensures rapid drying (typically within 20-30 minutes after rain) and eliminates puddles, allowing athletes to resume training almost immediately after rainfall.
