Key Advantages: Drains rain instantly | Breathable to release vapor pressure | Anti‑blistering even in monsoon | No standing water after 5 minutes | UV & hydrolysis resistant
This high‑permeability porous track is engineered for regions with heavy rainfall and high humidity. Its open‑cell structure achieves water permeability ≥2.5 mm/min (tested under ASTM E2396). Unlike solid sports surfaces, it never traps moisture underneath, preventing the blistering and delamination that plague traditional tracks in tropical climates.
Suitable for open‑air stadiums, coastal athletic fields, schools in monsoon zones, and any outdoor track that must remain usable shortly after rain.
| Parameter | Value | Requirement |
|---|---|---|
| Permeability (ASTM) | 2.5–3.5 mm/min | ≥2.0 |
| Thickness | 13mm (custom 10–20mm) | ≥13mm |
| Impact Absorption | 35–45% | 35–50% |
| Vertical Deformation | 0.6–2.2mm | 0.6–2.5mm |
| Slip Resistance (wet) | 0.65–0.8 | ≥0.5 |
| Blistering Resistance | No blisters after 72h water flooding test | — |
| UV Resistance (ΔE) | ≤3 after 1000h QUV | — |
Same layered construction but with higher binder content in the bottom layer to resist constant moisture.
| Layer | Material | Why |
|---|---|---|
| Base | Recycled or virgin SBR (2–4mm) | High porosity, low cost |
| Top | Virgin EPDM (1–3mm) | Color stable, UV resistant, non‑absorbent |
| Country | Project | Rainfall (annual) | Result |
|---|---|---|---|
| Kerala, India | University track | 3,100 mm | No puddles after 2 years |
| Costa Rica | National training centre | 3,500 mm | Zero blistering |
| Vietnam | International school | 2,200 mm | Used same day after rain |
Same 15‑30 day lead time. Optional waterproof packaging for sea shipment to tropical ports.
Q: Does algae grow in the pores?
→ Our top layer includes anti‑microbial additive (optional). Regular sweeping prevents any growth.
Q: Can it handle freezing after rain?
→ Yes. The open structure allows ice to sublimate without cracking the surface.
