Over time, synthetic and natural turfs begin to compact due to weathering, overuse, and lack of routine maintenance. Fields can also be subject to divots and low spots in natural turfs or displacement of infill on synthetic turfs. The harder the surface, the more dangerous it can become for the players whose bodies are absorbing the impact.

Field impact testing assists in honoring your commitment to safety and can protect players while keeping the investment of your facility performing at its highest level.
Measuring shock-attenuation is a fundamental tool of athletic field safety testing. The GMax test assesses the impact absorbed by the player’s body. As GMax values increase, shock-attenuation performance decreases. This results in an increased safety risk when the using the field.

Benchmarking and monitoring your field is a good first step in protecting your players.
Synthetic turfs are tested upon installation; however the shock-attenuation changes over time for all field types. Because of this, best practices call for a minimum of annual field testing, typically before the start of the playing season. For synthetic turfs, testing should be completed concurrent with annual grooming. Utilize best practices for field maintenance in coordination with impact testing will:
  • Demonstrate your commitment to a safe and functional facility
  • Identify potential safety issues to address in future facility planning, maintenance and budgeting
  • Establish a historical record of facility performance allowing easy reference for warranty and liability concerns
