We deliver top-tier Poured-in-Place Rubber: The Ultimate Playground Safety Surface solutions across our service areas, from the busy playgrounds of Charlotte to community spaces in Tucson, ensuring every project meets the highest standards.

The Two-Layer Construction Explained

The performance of EPDM wet pour rubber surfacing comes from its two-layer construction:

The Base Layer (Shock Absorption): This foundational layer is made of Styrene Butadiene Rubber (SBR) granules, sourced from recycled tires. Laid at depths from 25mm to 85mm, its primary function is shock absorption, providing the necessary cushioning to meet the Critical Fall Height (CFH) of play equipment. This is the core of the system’s safety, as detailed in our guide to Shock Absorbing Playground Surfaces.
The Top Layer (Durability and Design): This visible, 15-20mm thick layer is made from virgin Ethylene Propylene Diene Monomer (EPDM) rubber granules. Applied over the SBR base, it provides:
- UV Resistance: EPDM is highly resistant to sun damage, ensuring colors stay vibrant longer, whether in the Arizona sun or humid conditions in Lake Charles.
- Color Stability: Virgin EPDM granules allow for a vast palette of stable, non-fading colors.
- Softness and Durability: This layer adds softness underfoot and is incredibly durable, withstanding heavy foot traffic and weather fluctuations.

Both layers are bound with a specialized polyurethane resin to create a cohesive, resilient surface.

Key Material Components

Understanding the core materials is key to appreciating the quality of EPDM wet pour rubber surfacing:

EPDM (Ethylene Propylene Diene Monomer): These virgin rubber granules form the colorful top layer, known for excellent UV stability, chemical resistance, and long-term elasticity. Our EPDM granules contain up to 25% polymers with premium UV stabilizers for superior performance. Learn more at our EPDM Rubber Playground page.
SBR (Styrene-Butadiene Rubber): The workhorse of the base layer, SBR granules are derived from recycled tires, providing a sustainable source of shock absorption to meet fall height requirements.
Polyurethane Binder: This “glue” cures on-site to bond the rubber granules. There are two main types:
- Aromatic Binder: A cost-effective choice, though it may yellow slightly with UV exposure. This effect typically diminishes over time.
- Aliphatic Binder: A premium, UV-stable option that prevents yellowing and preserves the vibrancy of EPDM colors, especially lighter shades. It also improves durability.

The recycled content of our EPDM wet pour rubber surfacing is a point of pride. The SBR base is 100% post-consumer recycled material. The total recycled content of the entire system ranges from 82% to 96%, turning environmental waste into safe, functional spaces.
