Safest Artificial Turf Fields for Your Athletes & Programs

Since 2004, Brock has partnered with hundreds of schools, parks, universities, and professional leagues on their artificial turf projects. Brock is the only company that has engineered a shock pad product specifically for synthetic turf fields. You wouldn’t buy a used, recycled helmet to put on a valued athlete, and a shock pad under your turf performs the same function. Artificial turf fields are now a sophisticated system of components all aimed at mimicking a quality natural turf playing surface.

We have studied the brain, concussions, footing, speed, and how the surface impacts the athlete – literally. These fields are built for the players in your program today, but they need to last for years to come – without degrading in safety or performance. Your artificial turf field should mimic the qualities and safety of pristine natural turf as much as possible. The University of Tennessee Center for Athletic Field Safety provided the benchmarks to do just that. It also needs to work for your climate and the hours of use needed.

Shock Pads are the Standard for Modern Artificial Turf Fields

Here Are Reasons Why All Artificial Turf Fields NEED Shock Pads:

Increased use of alternative infills that require a shock pad Increased use of shorter turf pile heights Turf lasts longer over shock pads than directly on rock Increase in state legislation promoting concussion prevention
Increased awareness by players and parents of risks of brain injury and need for safety measures in turf Increased litigation related to unsafe athletic venues and related head injuries New safety standards related to G-Max and HIC allowable limits University research on natural turf so we know what the goal is!

Gracie Hussey’s Story – Impacts of Concussions on Her Life

What is CTE? Turf Impacts and Head/Brain Injuries

After the controversies surrounding the NFL’s denial of the repercussions from frequent sub-concussive blows to the head, concussions were brought front and center for all contact sports. The biggest revelations came after the publication of Dr. Omalu’s article in the Journal of Neurosurgery, “Chronic Traumatic Encephalopathy in a National Football League Player.” Dr. Omalu was the chief surgeon assigned to the autopsy of Pittsburgh Steeler Legend, Mike Webster. Webster died in 2005 homeless and financially bankrupt. Much of his fall from grace has been attributed to his plight with Chronic Traumatic Encephalopathy or “CTE.” The correlation of contact sports and the long-term effects of concussions and sub-concussive blows has forced many leagues, especially youth sports, to re-evaluate how the games are played.

What We Know About Concussion:

1 in 5

1 in 5 concussions involve the head hitting the surface

AGE 25

The brain does not fully develop until age 25 so it’s more susceptible to injury until then


It does not take a concussive level impact to cause brain injury


Brain injuries are cumulative


Recovery from a concussion can takes months or years

Young Necks

Young Necks are weaker, and therefore less able to stabilize the head during impact, so young athletes have more head movement upon impact than adults

Knowing what we do now about concussions in sports we have an increased responsibility to build the safest environment we can for these kids.– A.R., Director of Facilities

What Does Reducing HIC Mean for Head Injuries

23-50% reduction in the relative risk of common head injuries on the surface.


Y Axis – “Probability”

“Estimates for 5-year old surfaces showed a somewhat larger effect of the underlayment, directly attributable to the faster deterioration of impact attenuation performance of surfaces without underlayment.”– Biomechanica, 2009

Learn About Field Safety & Performance Testing

Three unique parts of the body produce different impact levels when contacting the surface, so 3 different test devices are used, each designed for a specific impact quality.




HIC is the internationally recognized test standard for head injuries. It drops a 10 lb hemispherical impacter from increasing heights to determine Critical Fall Height. It’s the same test used in playgrounds, automotive crashes, wall padding, pole vault, and the WR Reg22 standard for artificial turf. The higher the Critical Fall Height, the more protective the surface is for head injuries.




This test method covers the measurement of certain shock-absorbing characteristics, like during body impacts. It’s applicable to natural and artificial playing surface systems. It does not correlate to head injury. It drops a 20 lb flat missile from 24”. GMax is a good measurement when used in conjunction with HIC above, but as a standalone test is not a total measure of field safety.





This test simulates the heel strike of an adult running athlete in stride. This is the softness or hardness under foot during play. A great natural grass field hits the “sweet spot” of being firm under foot while producing very low gmax and high Critical Fall Height. Which is why quality natural turf is the benchmark for quality artificial turf.

The Next Generation of Sports Surface

Reduce Risk of injuries by putting performance safety layers under the field.

  • The original shock pad system that set all industry standards for artificial turf fields. PowerBase Pro provides the ideal balance between shock absorption and field stiffness for elite athletes and is the only product engineered for NCAA, Pro and elite level players.


  • The “younger brother” of PowerBase Pro, offers the same safety, drainage, cost, and environmental benefits as PowerBase Pro, but is the only artificial turf shock absorbing pads system engineered specifically for youth and recreational sports. Smaller bodies need a different surface than the pros!


  • If lateral drainage is not required, SP Series (stands for “Shock Pad) is a cost-effective, high-performance line of shock absorbing pads for use on new or replacement fields with an existing, well-draining stone base. It comes in different thicknesses to optimize safety for the turf you select.


  • slider-header-play

    This is our playground product. 2” thick, and engineered for critical fall heights under playground equipment. For use under artificial turf.
