Why “safest” depends on the system, not just the infill

Infill choices matter, but the shock pad under the turf does the heavy lifting for impact protection. You get reliable safety when the whole system is designed and tested together for your fall height.

What the shock pad does

  • Delivers impact attenuation that protects against head injury criteria at the rated fall height.
  • Stays consistent across cold and hot temperatures when specified correctly.
  • Reduces performance loss from infill migration and heavy traffic.

What the infill does

  • Stabilizes fibers and tunes surface feel for play.
  • Supports consistent energy absorption at the surface layer.
  • Helps manage aesthetics, cleanliness, and maintenance cycles.

EPDM vs TPE infill for playgrounds

Both EPDM and TPE are resilient, clean, and consistent options for playground turf systems. Pair either with a proven shock pad to reach your target fall height.

  • EPDM granules: Durable, color-stable, low dust, and widely used in play surfacing. Predictable particle sizing supports even coverage and feel.
  • TPE granules: Resilient, uniform, and clean. Offers strong elasticity and stable performance in a wide temperature range.
  • Other options, briefly: TPV can also perform well in play. Organic infills and coated sands can add stability, but they usually need a robust pad to achieve fall-height ratings and are less consistent for impact attenuation by themselves.

Safety standards you must hit

  • ASTM F1292 impact attenuation: Verify the complete turf system meets HIC ? 1000 and Gmax ? 200 at your design fall height. Confirm both lab and field results at relevant temperatures.
  • IPEMA listing: Request IPEMA-certified systems or third-party documentation for the exact build you plan to install.
  • ADA accessibility: Confirm ASTM F1951 accessibility on accessible routes.
  • CPSC guidance: Ensure the surface’s critical fall height meets or exceeds the highest designated play surface.

Specification checklist for a safer build

  • Map the highest designated play surface and target fall height.
  • Select a shock pad with lab reports showing compliance at that height across temperature ranges.
  • Choose EPDM or TPE infill that matches the tested system design. Follow the tested infill depth and particle size guidance.
  • Pick a playground-rated turf with appropriate pile height and stitch density for stability over the pad.
  • Detail seams, edges, and transitions to keep the surface uniform and accessible.
  • Require post-install field testing to ASTM F1292 before handoff.

Maintenance that keeps safety locked in

  • Groom routinely to redistribute infill and prevent hard spots.
  • Top off infill as needed to maintain the tested depth and even surface.
  • Schedule field testing at set intervals and after major repairs.
  • Manage heat with lighter infill colors, shading, or hydration plans where appropriate.

Heat, hygiene, and appearance

  • Lighter EPDM or TPE colors run cooler in sun than dark blends.
  • Choose clean, uniform granules to reduce dust and simplify cleanup.
  • Confirm cleaning protocols for spills, debris, and bio-contaminants without harming the system.

Typical system approaches by fall height

  • Up to 6 ft: Playground-rated shock pad paired with EPDM or TPE infill on playground turf. Verify lab and field tests for your climate.
  • 6 to 8 ft: Higher performing pad and the same resilient infill. Confirm HIC results at elevated temperatures.
  • 8 to 10 ft and above: Premium pad solution, tuned turf, and EPDM or TPE infill. Require robust third-party reports and on-site validation.

Common missteps to avoid

  • Specifying infill without a pad and expecting it to carry impact performance.
  • Mixing products that were not tested together for your fall height.
  • Skipping field testing at turnover or neglecting ongoing maintenance checks.

Procurement requirements that protect your project

  • Third-party lab report to ASTM F1292 for the exact system build at your fall height.
  • IPEMA listing or equivalent documentation for the system.
  • Field test results to ASTM F1292 after installation.
  • Clear maintenance plan and warranty terms that cover impact performance.
