The goal of any artificial turf surface is to mimic a high quality natural grass playing field.
Achieving this requires a more sophisticated approach than laying “rug over rock.” Think of Brock’s SP Series as the “intel inside” of your field. The SP Series shock pads have been specifically engineered to optimize safety for artificial turf during impacts.
Brock SP comes in several thicknesses, from 14mm to 20mm, depending on the turf you select, always keeping the performance of the overall system in mind. Fields that utilize an SP shock pad demonstrate the safety, speed and impact performance that replicates a quality natural turf surface, plus they drain fast, and they last longer.
Large robust dovetail interlock makes installation fast and easy.
Open pore structure allows water to pass vertically through material.
Micro coating bonds material and maintains porosity.
Interaction of particles keeps field stiff for running, soft for impacts.

Shock Pads that out perform all artificial turf pads on market
Brock’s SP series will outperform other “shock pads” nearly twice as thick. That’s because it’s engineered for artificial turf and the impact it will experience during play. A patented material using polypropylene with a microcoating binder produces a material with an open pore structure for fast drainage and a unique impact profile ideal for artificial turf.
Critical Fall Height
Benchmarking natural turf
There are three measurements used to characterize safety and performance of a surface
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.
Safety to last, plus Drainage benefits for Artificial Turf Fields
OUR GOAL WAS SIMPLE: A PRISTINE NATURAL GRASS FIELD WILL DELIVER A G-MAX OF 90-100, AND BE FIRM AND FAST TO PLAY ON. A SHORTER PILE SYNTHETIC FIELD OVER BROCK SP WILL DO THE SAME THING. AND MAINTAIN IT FOR THE LIFE OF THE FIELD. TESTING SHOWS HOW EVEN AFTER YEARS OF HIGH IMPACTS, THE GMAX OF THE FIELD IS LOW AND STABLE.

Vertical permeability of Brock SP is far greater than the turf itself, so as long as the stone base below and the turf above allows water to pass, Brock SP will only enhance drainage.
When you replace your turf, shockpad series is reused for the next turf life.

When should I use the Brock SP Series?
Replacing an old, hard synthetic turf field.
Using a shorter turf and SP results in better play and greater safety, doesn’t change the field profile, and offsets some of the cost of the pad.
New synthetic fields designed with a draining stone base, where long term safety is required.
Again, we recommend a slightly shorter turf over SP. The thickness of the SP is determined by the turf you select. The shorter pile turf, the thicker the SP should be in order to attain the highest safety levels possible.
