A Sandwich Running Track is a high-performance athletic surface composed of multiple strategically bonded layers — starting with a resilient rubber base and topped with a sealed polyurethane/EPDM wearing layer. This “sandwich” structure provides an impermeable, spike-resistant surface that supports athletes with consistent traction and comfort. For dedicated jogging paths and park surfaces, explore our EPDM Jogging Track system.

Applications:

Professional & school athletics tracks

Competitive and training facilities

Community jogging and walking paths

Durability & Weather Resistance

The bonded base and top layers protect against wear, UV fading, and extreme climates — ensuring long-lasting performance year after year.

Elite Athlete Safety & Comfort

Designed to reduce impact on joints while providing excellent traction, this system supports athletes during sprints, training, and competitive events.

Cost-Effective Solution

Low maintenance needs and robust construction make this track surface a smart long-term investment for schools, clubs, and stadiums.

Low Maintenance & Seamless Finish

Seamless installation means fewer joints, less wear, and easy cleaning — reducing downtime and upkeep costs.

Primer Layer

Prepares and bonds the base surface using high-quality PU primer.

What is the Sandwich Running Track System and how is it constructed?

The Sandwich Running Track System is a multi-layer synthetic athletics surface built from four bonded layers: a polyurethane primer base, an elastic SBR rubber granule layer mixed with PU binder, a polyurethane pore sealing layer for impermeability, and a final PU and EPDM broadcast wearing surface. The total system thickness is typically 13–15 mm. This layered "sandwich" construction creates a spike-resistant, impermeable, and high-traction running surface suitable for school, district, and state-level athletic competition across Australia.

What is the difference between a Sandwich Running Track and a Spray Coat Running Track?

The key difference is construction depth and performance level. A Sandwich Running Track System includes a dedicated PU sealing layer between the rubber base and wearing surface, making it impermeable, spike-rated, and suited to competitive athletic use. A Spray Coat Running Track omits this sealing layer and uses a spray-applied wearing surface instead, making it more affordable but better suited to recreational, community, and school training use rather than formal competition. The Sandwich system generally offers higher shock absorption (35–40%) and a longer lifespan of 8–12 years.

Is the Sandwich Running Track System suitable for competitive athletics in Australia?

Yes. The Sandwich Running Track System is suitable for school, district, and state-level athletics competition in Australia. Its spike-rated wearing surface, ≥35% shock absorption, and impermeable sealed construction meet the performance requirements for formal athletic events at these levels. The system is installed in compliance with recognised athletics surface guidelines. For national or international events requiring full IAAF World Athletics certification, a Full PU Running Track system with independent laboratory testing is recommended.

How long does a Sandwich Running Track last and what affects its lifespan?

A properly installed Sandwich Running Track System in Australia has an expected lifespan of 8 to 12 years. Key factors that influence longevity include the frequency and intensity of athletic use, the quality of base preparation, local climate conditions (particularly UV intensity), and regularity of cleaning and surface inspections. The impermeable PU sealing layer in the sandwich construction plays a major role in protecting the rubber base from moisture, which is one of the primary causes of premature surface degradation in running tracks.

Why does the Sandwich Running Track System include a sealing layer and what does it do?

The sealing layer is what distinguishes the Sandwich Running Track System from simpler spray coat or EPDM surfaces. It is a high-grade polyurethane pore filler applied over the elastic rubber base before the top wearing layer is installed. This sealing layer closes all open pores in the rubber base, making the entire system waterproof and preventing water from penetrating to the foundation below. Without this layer, moisture ingress can weaken the bond between layers, cause surface lifting, and significantly shorten track lifespan — particularly in Australia's high rainfall coastal regions.
