EPDM (Ethylene Propylene Diene Monomer)

rubber is commonly used in the wet-pour system for safety surfaces, especially in applications such as playgrounds, sports facilities, and recreational areas. The wet-pour system involves mixing EPDM rubber granules with a polyurethane binder to create a seamless and impact-absorbing surface. Here’s a closer look at the use of EPDM in wet-pour applications:

1. Composition:

• EPDM Granules: These are small rubber particles made from EPDM, providing flexibility, resilience, and durability.
• Polyurethane Binder: The binder is a liquid material that, when mixed with EPDM granules, forms a solid, seamless surface upon curing. It acts as the adhesive and binding agent.

2. Installation Process:

• Substrate Preparation: The existing surface is prepared by cleaning and, if necessary, repairing any damage.
• Primer Application: A primer may be applied to enhance the adhesion of the wet-pour system to the substrate.
• Mixing Components: EPDM granules are thoroughly mixed with the polyurethane binder in specific ratios. This mixture can be customised to achieve desired properties such as thickness, colour, and resilience.
• Pouring and Spreading: The mixed material is poured and spread onto the prepared surface. The wet-pour method allows for a seamless and uniform application.
• Smoothing and Finishing: The surface is then smoothed to achieve an even and level finish.

3. Advantages of EPDM in Wet-Pour:

• Impact Absorption: EPDM’s elastic properties contribute to the wet-pour system’s ability to absorb impact, providing a safer surface in case of falls or accidents.
• Durability: EPDM is known for its durability and resistance to wear, making it suitable for high-traffic areas.
• Weather Resistance: EPDM is highly resistant to UV radiation and weathering, ensuring the longevity of the wet-pour surface in outdoor applications.
• Colour Options: EPDM is available in a variety of colours, allowing for creative and customisable designs. This is particularly beneficial in applications such as playgrounds where vibrant and visually appealing surfaces are desired.
• Flexibility: EPDM maintains flexibility over a wide temperature range, ensuring that the wet-pour surface remains resilient in different weather conditions.

4. Applications:

• Playgrounds: EPDM in wet-pour is widely used in playgrounds to create impact-absorbing surfaces, minimising the risk of injuries from falls.
• Sports Surfaces: Wet-pour surfaces with EPDM are utilised in sports facilities, including multi-use games areas (MUGAs) and athletic tracks, providing a comfortable and safe surface for various activities.
• Recreational Areas: Wet-pour surfaces with EPDM are suitable for recreational spaces, providing a safe and visually appealing environment.

5. Maintenance:

• Wet-pour surfaces with EPDM generally require minimal maintenance. Regular cleaning and inspections can help ensure the surface’s longevity and performance.

6. Environmental Considerations:

• EPDM rubber granules used in wet-pour systems can be sourced from recycled materials, contributing to sustainability efforts.

In summary, EPDM in wet-pour applications combines the durability and weather resistance of EPDM with the safety and design flexibility of the wet-pour system. This makes it a popular choice for creating impact-absorbing and visually appealing surfaces in various outdoor settings.
