Synthetic / Natural Turf G-MAX Testing

Sports Turf International is one of only a few Independent certified G-max testers in Canada. Synthetic/Natural turf g-max testing including infill depth, fiber evaluation and documentation.

What is G-Max?

Essentially G-max is the measure of how much force the surface absorbs and in return, how much is returned to the athlete.

The more technical definition of G-max = the maximum negative acceleration on impact (which is measured in G's). For example, a high G-Max reading (> 200 G) would indicate less absorption of force by the surface and consequently a high risk factor for potential head injuries and/or life threatening situations.

All G-Max testing conforms to standards ATSM 1936 and F355

Why is it important to perform a G-max test on your natural or synthetic sports field?

1. For some artificial turf surfaces an annual G-max test is required to validate the turf warranty from the manufacturer. A proper Gmax reading helps demonstrate that the surface is being maintained correctly.

2. Demonstrates a proactive approach to safety.

3. Potentially help protect field owners from lawsuits.
