three points of safety
PREVENTING CONCUSSIONS IN SPORTS HAS BECOME A NATIONAL PRIORITY.
1 in 5
Studies show 1 in 5 concussions occurs by head to surface impact, WHICH IS WHY BROCK HAS DEDICATED COUNTLESS HOURS TO PERFECTING THE RIGHT PRODUCT FOR THE UTMOST PLAYER SAFETY.
How do we test impact safety?
Only infilled turf over a quality shock pad can reach player safety ranges found in natural grass. We know this from the data collected from the GMAX test, the HIC test, and a foot impact test on fields of all types. This gives a more comprehensive picture of how the field is performing from an impact safety standpoint.
HEAD INJURY CRITERI0N (HIC)Head Impact Test
- The HIC test correlates with the likelihood and severity of a head injury, has been used to test playground surfaces for decades, and was adopted by ASTM for athletic fields in 2016.
- The HIC impact test drops a 10.1 lb. hemisphere projectile (curved like a human head) multiple times from increasing heights and determines the surface’s Critical Fall Height. The higher the Critical Fall Height, the safer the surface. A good natural grass field will produce a minimum critical fall height of about 6 feet or higher.
GMAXBody Impact Test
- The GMax test is not correlated with head injury risk. The GMax test drops a 20 lb. flat missile from just 2 feet high. The higher the GMax value, the harder the surface. A good natural grass field (the benchmark for a quality athletic field) will produce a GMax below 100 and often below 80.
- Artificial turf over stone will produce a GMax above 140 and frequently higher, meaning far more impact energy is absorbed by the body than by the surface. Turf over a Brock Shock Pad will mimic the low Gmax of natural grass without making the field soft to run on. (Study: the University of TN Dept. of Biomechanics, 2016.)
deformationFoot Firmness Impact Test
- This test simulates the heel strike of an adult running athlete in stride. In other words, it measures the softness or hardness underfoot during play on a field.
- A great natural grass field hits the “sweet spot” of being firm underfoot while producing very low Gmax and high Critical Fall Height.
- This is why quality natural turf is the benchmark for quality artificial turf.

Dartmouth Football has been a pioneer of safety innovation for nearly a decade. With Coach Teevens at the helm, Dartmouth football eliminated all player-on-player tackling in practice. In 2016 they continued their safety mission by installing a Brock Shock Pad System for their Artificial Turf Field.
