What Are Rubber Granules?
Rubber granules — also known as rubber crumb — are small particles of rubber produced by recycling end-of-life tires or specially manufactured rubber compounds. These granules vary in size and are used as base material in rubber flooring systems.
In sports flooring, rubber granules act as the shock-absorbing core that protects athletes, reduces impact, and improves comfort underfoot. They are mixed with binders and compressed into tiles, rolls, or poured-in-place systems. Sports facilities, school gyms, playgrounds, and fitness centers frequently use rubber granule-based flooring because it outperforms most traditional floors in safety and performance.
Why Rubber Granules Are Perfect for Sports Flooring
Rubber granules offer several benefits that make them ideal for sports and fitness flooring:
????️ Superior Shock Absorption
Rubber granules cushion impacts from jumps and falls, helping reduce injury risk.
???? Enhanced Traction & Grip
The stable yet flexible structure improves traction — important for dynamic athletic movements.
???? Noise Reduction
Rubber flooring systems reduce noise and vibration — ideal for gyms and indoor courts.
???? High Durability
Granule-based floors withstand heavy foot traffic, weights, and equipment without premature wear.
???? Easy Maintenance
These surfaces are simple to clean and maintain, ensuring long-term hygiene.
EPDM vs SBR Rubber Granules: What’s the Difference?
Rubber granules used in sports flooring are mainly available in two types: EPDM and SBR. Each has its distinct characteristics and best-use scenarios.
???? SBR Rubber Granules (Styrene-Butadiene Rubber)
SBR granules are typically manufactured from recycled rubber and form the base layer of most shock-absorbing sports surfaces.
Key Features:
✔ Excellent shock absorption
✔ Cost-effective
✔ Strong durability
✔ Good resistance to heavy foot traffic and impact
Best For:
✔ Base layers of sports flooring
✔ Gym flooring
✔ Weightlifting and multipurpose areas
✔ School play areas
➡️ SBR granules are often mixed with binders like PU to form strong, cushioned flooring suitable for general athletic and recreational areas.
???? EPDM Rubber Granules (Ethylene Propylene Diene Monomer)
EPDM granules are premium synthetic rubber particles known for color stability, UV resistance, and long-lasting performance.
Key Features:
✔ Excellent UV & weather resistance
✔ Vibrant, long-lasting colors
✔ High surface elasticity
✔ Premium shock absorption
Best For:
✔ Outdoor sports courts
✔ Playground surfaces
✔ Multi-use athletic areas
✔ Weather-exposed environments
➡️ EPDM granules are often used as the top layer in poured-in-place and prefabricated sports flooring systems because of their superior performance and aesthetic appeal.
How Rubber Granules Are Used in Sports Flooring
Rubber granules are typically combined with binders like polyurethane (PU) or latex to form cohesive flooring systems:
???? Poured-In-Place Rubber Flooring
A mix of EPDM or SBR granules with binder is poured and cured onsite, creating a seamless, impact-absorbing surface.
???? Rubber Tiles & Rolls
Granules are compressed and bonded into tiles or rolls that are installed with adhesive for stable, modular sports floors.
???? Shock Pads & Underlays
Rubber granules form shock pads beneath synthetic turf or PVC flooring for enhanced impact protection.
These systems are widely used in schools, training centers, gyms, playgrounds, and indoor courts.
Choosing the Right Rubber Granules for Your Project
When selecting rubber granules for sports flooring, consider:
???? Application Area
EPDM granules are ideal for outdoor and decorative layers, while SBR works well as a base layer for shock absorption.
???? Traffic & Load
High-traffic areas with heavy equipment benefit from strong SBR base layers.
???? Weather Exposure
Outdoor courts and playgrounds benefit from EPDM’s UV and color stability.
???? Budget
SBR granules are cost-effective, while EPDM adds performance features at a premium price.

Installation Tips for Rubber Sports Flooring
A high-quality rubber flooring system requires careful installation:
✔ Ensure a clean, level subfloor
✔ Choose appropriate granule type and binder
✔ Use professional installation teams
✔ Follow curing and drying times
✔ Regularly inspect surface for wear
Correct installation extends flooring life and ensures optimal performance.
Maintenance & Care
Rubber sports floors are low-maintenance, but proper care improves longevity:
???? Cleaning
Sweep or vacuum regularly to remove dust and debris.
???? Mopping
Use mild detergent solutions for deep cleaning.
???? Inspection
Periodically check for surface wear, especially in high-impact zones.
???? Avoid Harsh Chemicals
Avoid solvents that degrade rubber and binders.
Rubber Granules & Sustainability
Using recycled rubber granules supports sustainability by:
✔ Reducing landfill waste
✔ Promoting circular economy practices
✔ Conserving raw materials
✔ Supporting eco-friendly product development
Rubber granules convert waste tires into high-value flooring materials — a win for performance and the planet.
Final Thoughts
Rubber granules form the backbone of modern sports flooring systems. Their ability to absorb shock, reduce noise, and improve traction makes them ideal for gym floors, playgrounds, courts, and multisport facilities.
Understanding the difference between EPDM and SBR granules helps you choose the right material based on performance needs, budget, and installation environment.
