Common Questions & Answers



What is Field Hardness?

How is Field Hardness Tested?

Field hardness measures the ability of an athletic field to absorb shock.  Energy created when a player falls is partly absorbed by both the player and the field surface.  A harder surface forces the player to absorb more of the energy, placing him or her at a greater risk for serious injury.

STTS utilizes a method of testing that measures the peak deceleration, also known as the Gmax, of a 20 pound weight dropped from a 2-foot height.  The average Gmax should always be less than the one stated in the manufacturer's warranty.  



When Should Hardness Testing Be Performed?

How Long Does Testing Typically Take?

We recommend that you have your fields tested twice per year.  Testing can be done anytime the sub-grade is not frozen.  All new surfaces should be test within 30 days of installation to establish the baseline hardness and to insure proper installation.

Our state-of-the-art equipment enables us to be very efficient.  An average football or soccer field requires fewer than two hours for testing.  A comprehensive report is sent to you within six business days following the test.
