Modern running track systems are made from polyurethane-based materials combined with EPDM (Ethylene Propylene Diene Monomer) rubber granules. These synthetic materials provide resilience, slip resistance, shock absorption, and weather durability—key factors in ensuring athlete safety and long-lasting track performance.
The Spray Coat System and the Sandwich System are both certified by organizations like World Athletics (formerly IAAF) when installed correctly. Choosing between them depends on budget, intended usage, and expected lifespan.
2.1 Overview
The Spray Coat System (often called a “textured spray track”) is one of the most economical options for synthetic running tracks. It consists of a structural base layer with a thin sprayed-on polyurethane and EPDM coating, creating a textured surface.
2.2 Composition & Layers
- Base Layer – Asphalt or concrete foundation, properly graded and sealed.
- Polyurethane Structural Layer – Poured-in-place PU mixed with black SBR granules.
- Spray Coat Finish – Spray-applied colored polyurethane mixed with fine EPDM granules.
- Cost-effective – Lowest initial investment compared to other systems.
- Durable for schools & community tracks – Sufficient for training and moderate competition.
- Textured grip – Provides slip resistance in wet or dry conditions.
- Easy maintenance – Damaged top layer can be recoated without full replacement.
- Thinner wear layer – Shorter lifespan compared to sandwich systems.
- Not ideal for elite competitions – More suitable for training and school-level events.
- Less cushioning – May be less comfortable for long-distance training.
- School tracks
- Municipal or community sports facilities
- Multi-purpose outdoor areas
3.1 Overview
The Sandwich System is a mid- to high-performance synthetic track system designed for more intensive athletic use. It is called “sandwich” because of its layered build-up: a base layer of PU and SBR granules is sealed, then an additional PU layer is installed, followed by a full broadcast of EPDM granules.
3.2 Composition & Layers
- Base Layer – Asphalt or concrete sub-base.
- In-situ PU & SBR Base – Poured polyurethane mixed with black recycled rubber.
- Sealing Layer – PU applied to close the pores of the base.
- PU Layer – Liquid polyurethane layer applied over the sealed base.
- EPDM Broadcast Layer – Colored EPDM granules broadcast into the PU and sealed to create a durable, UV-stable surface.
- Higher durability – Thicker wear surface compared to spray system.
- Better comfort & shock absorption – More cushioning reduces injury risk.
- Longer lifespan – Typically lasts longer with proper maintenance.
- Suitable for competitions – Can meet World Athletics certification standards.
- UV and weather resistant – Withstands harsh climates better.
- Higher cost – More expensive than spray coat system.
- Longer installation time – Requires multiple layers and curing steps.
- Requires skilled contractors – Proper technique is essential to achieve performance standards.
- Professional athletic facilities
- Universities and high-performance training centers
- Stadiums for track & field competitions
| Feature | Spray Coat System | Sandwich System |
| Cost | Lower (budget-friendly) | Higher (investment-grade) |
| Performance | Suitable for training & schools | Suitable for competitions & elite use |
| Durability | 5–7 years (with maintenance) | 8–12 years (with maintenance) |
| Comfort/Cushioning | Moderate | High |
| Installation Time | Faster | Longer |
| Maintenance | Simple re-spray possible | More complex, but long-lasting |
Both systems require proper maintenance to extend lifespan:
- Regular cleaning – Remove debris, dirt, and organic growth.
- Surface inspection – Check for cracks, wear, or drainage issues.
- Recoating (Spray Coat) – Spray systems may require re-application every few years.
- Seam repairs (Sandwich System) – Address any granule loss or PU cracks quickly.
Choosing between a Spray Coat System and a Sandwich System depends on the intended use, budget, and performance requirements:
- Spray Coat System: Ideal for schools, community fields, and cost-conscious projects.
- Sandwich System: Best for professional sports facilities, universities, and competition-level stadiums.
