SRB Shockpad System Overview
The PLAYSaFE® SBR Shockpad System is an impact‑attenuating base layer system used within compliant wet‑pour rubber surfacing systems.
Wet‑pour is the installation system — not a product. Impact performance is achieved only through the correct on‑site installation of a complete system, not through individual materials.
The SBR shockpad is never a finished surface and is never specified, installed, or assessed in isolation. It is designed solely to deliver critical fall‑height impact attenuation where required and to support compliance with applicable standards when installed to specification.
SBR Shockpad Impact Performance & Fall-Height Design
Impact performance is thickness‑dependent and is engineered on a project‑specific basis.
PLAYSaFE impact performance data is derived from laboratory testing of complete wet‑pour systems under controlled conditions. Individual site applications are not tested. Tested system configurations form the basis from which project specifications are developed.
Indicative system thickness ranges include:
- 25–40 mm – low‑impact play areas
- 45–70 mm – standard playground equipment
- 75 mm+ – higher fall‑height structures
Final system thickness is determined by:
- Required critical fall height (CFH)
- Applicable standards
- Equipment configuration
- Substrate condition
When a tested system configuration is correctly specified and installed in accordance with PLAYSaFE requirements, the installed surface delivers the impact performance demonstrated during laboratory testing.
Substrate Requirements for SBR Shockpad Performance
Correct substrate preparation is critical to shockpad performance and longevity.
Suitable substrates include:
- Structurally sound, level, and fully cured concrete
- Correctly compacted and drained asphalt
- Engineered granular bases (e.g. compacted G5/G7 or equivalent), designed and constructed to PLAYSaFE® specifications
- Other engineered base constructions approved by PLAYSaFE®
Poor substrate preparation undermines system performance expectations, regardless of material quality.
