Choosing the Right Athletic Track Surface: Sandwich vs Porous Systems Explained

When planning a new athletic track or upgrading an existing one, choosing the right athletic track surface is one of the most important decisions you will make. While it may seem straightforward, the surface you select affects performance, safety, drainage, maintenance, lifespan and budget.

At Smart Surfacing, we understand there is no one-size-fits-all solution. The right choice depends on how the track will be used, how often and the level of competition it needs to support.

In this blog post, we explain the difference between sandwich systems and porous systems, helping you choose the best athletic track surfacing for your needs.

Why the Right Athletic Track Surface Matters

An athletic track is a long-term investment, so selecting the right surface is essential for creating a safe, durable and reliable facility.

The right athletic track surface affects athlete comfort and performance, drainage and weather resistance, maintenance requirements and long-term repair costs. It also determines whether the track is suitable for training, recreational use or competitive events.

Rather than choosing based on cost alone, it is important to match the surface to your specific requirements. A well-suited surface will deliver better value over time.

The Two Main Types of Athletic Track Surfacing

Most synthetic athletic track surfaces fall into two main categories:

• Porous systems

• Sandwich systems

A sandwich system is a type of non-porous surface, so comparing sandwich vs porous systems means comparing a higher-performance option with a more cost-effective one.

What Is a Porous Athletic Track Surface?

A porous athletic track surface allows water to pass through the surface into the sub-base below. This natural drainage makes it a practical and widely used option.

Porous systems are commonly chosen for schools, colleges and local athletics clubs because they offer a good balance between performance and cost.

Benefits of Porous Athletic Track Surfacing

Porous surfaces are cost-effective and provide reliable performance for everyday use. Their drainage helps prevent water build-up, and they offer a slightly softer feel underfoot, which is often preferred for training.

They are well suited to education and community settings where the track is used regularly but not at an elite level.

Considerations with Porous Systems

Porous systems typically require more maintenance over time. Their open structure means they can wear faster in high-use areas, especially where usage is heavy.

For this reason, they are best suited to facilities that need a dependable athletic track surface for training and general use rather than high-level competition.

What Is a Sandwich Athletic Track Surface?

A sandwich athletic track surface is a non-porous system built in layers. It combines a rubber granule base with a solid polyurethane top layer to create a durable, high-performance finish.

The structure usually includes an SBR rubber base and a coloured EPDM top layer, which improves grip, durability and overall performance.

Sandwich systems are often used for athletic tracks with higher usage or more demanding performance requirements.

Benefits of Sandwich Track Systems

Sandwich systems are known for their durability and consistent performance. They are designed to handle frequent use while maintaining quality over time.

They also require less maintenance than porous systems and offer many of the benefits of a full solid system at a more accessible cost. This makes them ideal for competitive environments and busy facilities.

Considerations with Sandwich Systems

The main drawback is the higher upfront cost compared to porous systems. However, this is often balanced by a longer lifespan and reduced maintenance needs.

For many facilities, a sandwich system provides an excellent balance between performance, durability and long-term value.

Sandwich vs Porous Systems: Key Differences

The main differences between sandwich and porous athletic track surfaces come down to drainage, durability, performance and cost.

Porous systems allow water to drain through the surface, making them effective in wet conditions and more affordable initially. They are softer underfoot and ideal for schools and community facilities, but may require more maintenance over time.

Sandwich systems are non-porous, meaning water drains away across the surface. They offer greater durability and improved performance, making them better suited to high-use or competition-focused athletic tracks. Although they cost more upfront, they often provide better long-term value.

Which Athletic Track Surface Is Right for You?

The best athletic track surface depends on how the facility will be used.

Porous systems are ideal for schools, colleges, community sports facilities and local athletics clubs where budgets are tighter and the focus is on training and general use.

Sandwich systems are better suited to high-use tracks, competitive clubs and facilities hosting regular events. They are a good choice where durability and long-term performance are priorities.

If you need an affordable and reliable athletic track for everyday use, a porous system is likely the right option. If you require a more durable, high-performing surface, a sandwich system is usually the better choice.

Performance, Safety and Longevity

An athletic track is not just about the surface. A successful facility must also be safe, accurate and built to last.

This includes correct layout, effective drainage, durable materials and regular maintenance. All of these factors contribute to performance and lifespan.

At Smart Surfacing, we take a tailored approach to every project, helping clients choose the right athletic track surfacing based on usage, performance needs and budget.

Maintenance Matters

Whatever athletic track surface you choose, maintenance is essential to protect your investment.

Porous systems generally need more frequent upkeep, while sandwich systems are more resistant to wear. However, both require regular cleaning, line remarking and timely repairs.

Ongoing maintenance helps improve safety and extend the life of your athletic track surface.

FAQs About Athletic Track Surfacing

What is the best athletic track surface?

It depends on usage. Porous systems suit schools and community use, while sandwich systems are better for higher-use and competitive environments.

What is the difference between porous and non-porous surfaces?

Porous surfaces allow water to drain through them, while non-porous surfaces direct water away across the surface.

Is porous athletic track surfacing cheaper?

Porous systems are typically more cost-effective upfront.

Is a sandwich track better than a porous track?

Sandwich systems are more durable, but porous systems are often better for lower-cost, general use.

How long does an athletic track surface last?

This depends on usage and maintenance, but regular care will extend its lifespan.

Can an athletic track be repaired or resurfaced?

In many cases, resurfacing is possible depending on the condition.
