Heat stress is a major safety issue with artificial turf. In many areas in the U.S., temperatures of an artificial turf field with crumb rubber can exceed 175° F.

We don’t make turf. We make turf cooler.

Everyone knows artificial turf has a heat problem, but the use of cheap crumb rubber has prevented a solution. Until now.

The solution is BrockFILL

Finding a material that could address the issues associated with crumb rubber, as well as the durability, cost, and availability challenges of other organic infills, was no small task. BrockFILL is a 100% organic wood infill sourced from sustainably cultivated and harvested trees in the USA. Southern Pine, which is both safe and prevalent, has been utilized by humans for centuries. However, transforming this raw material into an infill necessitated an entirely novel process. Therefore, we created a unique 9-step process to yield smooth, rounded particles that facilitate efficient drainage, cool the field, and provide the necessary natural foot traction.

How we test for heat


BrockFILL is a significantly cooler infill than crumb rubber and does not require watering. Each BrockFILL particle is naturally hydrophilic, so they absorb natural rainwater and condensation into their core, not just on the surface. Moisture is then released slowly for extended cooling. Plus BrockFILL gains weight when wet, so it doesn’t float or
migrate like cork.

We measured two adjacent fields in the same location, with the same turf product, the same day, the same time, and both were dry. The BrockFILL field measured 33 degrees cooler than the crumb rubber field with a cooling agent added. Plus the lower thermal conductivity of BrockFILL reduced heat transmission through shoes and skin. The difference is even greater after a rain.

A cooler surface can reduce dehydration which in turn can reduce risk of injury.

“The risk of heat cramps increases when you aren’t properly hydrated. As your body loses water during physical activity, your muscles can become tense. This interferes with your athletic performance and can make you more likely to injure yourself. Muscle strains, tears, and bone fractures are common effects of exercising with tense, cramped muscles.”

Watch Now

Artificial turf fields with Crumb Rubber can reach dangerously high temperatures and can increase the risk of heat related injuries for athletes. BrockFILL dramatically lowers the surface temperatures of these fields.
