Laying synthetic turf directly over rock is simply an old and risky idea. The base is unreliable, it’s expensive, it moves, it clogs, it’s bad for the environment, and the field gets hard. Really hard. So we designed a base system to solve these common problems. One that’s safer for the players, drains faster, lasts longer, saves money and preserves the environment. And then we precisely tuned it to reduce the likelihood of impact injuries in youth and student athletes, and recreational sports.
We started the revolution over a decade ago. Teams at all levels in over 19 countries around the globe have joined us.
Now it’s your turn.
Stair step edge supports turf and prevents shadowing through turf.
Conical piston shape reacts dynamically to variable running loads for more natural feel of play. G-Max guarantee.
Millions of drain holes on every field line up with channels on bottom.
Shock absorbing structures.
Large high volume drainage channels.
Drain channels are continuous between panels for water flow.
Crush ribs control fit during installation.
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
Head Injuries are a serious subject.
Only by understanding impacts to the brain and body could we engineer the highest safety and performance shock layer available. You wouldn’t buy a used helmet with a recycled foam liner to protect a kid’s brain, and the same applies to your artificial turf shock pad.
Critical fall height (HIC) is the internationally recognized standard for head injury. You want your field to have the highest critical fall height possible, like that of a high quality natural grass. When PowerBase YSR is used under a proper infilled turf system, Critical fall height, GMax and vertical deformation all mimic that of a quality natural grass and significantly improve the safety of the field. Turf over stone simply does not.
For young adults this is especially important, since the human brain is not fully developed until age 25. Young brains lack the mylenation that strengthens the nerve cells and helps protect against concussion. Combined with weaker necks, lack of skills, and the cumulative effect of sub concussive head impacts, protecting the young brain from surface impacts is even more important than doing so in adults.
Reduction in the relative risk of common
head injuries on the surface.
“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
Understanding Surface Impacts
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.

Proven, fast drainage
Brock PowerBase YSR has large lateral channels that transport water to the collector system along the edge.
ASTM D3885 Dual-ring infiltrometer testing on fields that use the Brock cross section have shown field drainage rates of greater than 70” per hour. EN12616 drainage test produces vertical drainage of the panel alone greater than 100” per hour.
