More Than a Shock Pad.
The Foundation of a Better Field.

A ShockPad for Every Turf

We view the field as a piece of equipment that has a significant impact on an athlete’s safety. We are of the firm belief that a safer system not only enhances player protection, but also offers quicker drainage, prolonged durability, and environmental preservation.

Precision at every turn

PowerBase YSR is made from expanded polypropylene, one of the most durable polymers on earth. Each panel is molded individually, allowing precise quality control. This results in a field that is flat and consistent underfoot. It is also recyclable without ever losing performance. A proper artificial sports surface is tuned for the athletes using it. PowerBase YSR was engineered for schools, recreational fields and for use with organic infills.

Achieving the proper performance levels for Impacts, Heat and Traction in a quality artificial turf defines the modern sports surface design.

By using the various standardized tests, we can now create an artificial surface as close to natural as ever before. The green areas designate the desired performance ranges of quality natural turf. The spokes indicate the performance results of the artificial turf field systems described in the center. Keep in mind, the turf pile height ranged from 1.5”-2.0” and consisted of products from every brand of turf, yet all of the systems performed well.

Solving drainage problems with PowerBase YSRXD

When artificial turf is replaced, the underlying stone base has most likely changed. Over time, the base’s flow rate degrades, leading to poor water drainage that can impact the new turf. PowerBase YSRXD builds on the proven drainage of our standard YSR Pad, enhancing drainage for areas with extreme rainfall or compromised bases.

Superior Drainage Performance

YSRXD is Engineered to manage water when the base doesn’t. PowerBase YSRXD ensures that storm water is efficiently channeled away from the field, reducing the risk of damage to both the turf and the underlying base.

Increased Safety & Durability

The impact and performance characteristics of PowerBase YSRXD adds a level of safety not achievable with turf placed directly over stone, more closely mimicking the qualities of great natural grass.

Faster Installation

Forget the hassle of tearing out and replacing the entire stone base. PowerBase YSRXD provides a high-performance drainage layer that can be quickly installed, saving time and expense. Your turf is ready for reinstallation in a fraction of the time.

Cost-Effective

The high capacity drainage of YSRXD solves drainage issues without the need for costly stone base replacement, while also improving safety and extending the life of the turf.

Frequently Asked Questions

PowerBase YSR is molded from 100% expanded polypropylene (EPP) and installed as interlocking panels beneath the turf. Its defining feature is lateral drainage — water moves horizontally through engineered channels at over 500 inches per hour, faster than the turf above it, so fields stay playable through heavy rain. The pad is dimensionally stable across freeze-thaw cycles and all climate conditions.

Most pads can hit their numbers on installation day. The harder question is what they read in year ten. PowerBase YSR carries a Gmax guarantee below 120 for the life of the field, not just at handover — and because the pad is a one-time installation that stays in place when the turf above it is replaced, every subsequent turf replacement costs less. Boise State installed Brock pads at Albertsons Stadium in 2008 and put the same pads back down when the blue turf was replaced in 2019, still performing as originally installed.

PowerBase YSR performance is verified through Gmax testing for impact force reduction, HIC testing for head injury criteria, and foot impact testing — measured both when new and over the life of the surface. The pad is Cradle to Cradle Certified, the only shock pad line in the artificial turf industry to hold that designation, which independently verifies material health including PFAS and restricted substance compliance.

PowerBase YSR is manufactured from 100% pure expanded polypropylene — non-toxic, resistant to bacteria and fungi, and fully recyclable at end of life. It contains no intentionally added PFAS and produces no microplastics. Because the pad outlasts multiple turf replacements rather than being landfilled alongside them, its practical environmental footprint is a fraction of systems that are replaced on every turf cycle.

Brock PowerBase YSR and YSRXD has earned C2C Certified® Material Health Bronze and C2C Certified® Circularity Bronze under version 4.1. These certifications evaluate material health and circular product design, supporting Brock’s commitment to protecting players and the planet.

PowerBase YSR carries a 25-year warranty covering structural durability, paired with a Gmax guarantee below 120 for the life of the field. That combination is unusual in this industry — most warranties cover the material but say nothing about whether the surface still performs safely a decade later.

Each Brock PowerBase YSR shock pad measures 42 inches wide × 61.1 inches long × 0.98 inches thick (25 mm). Each pallet contains 50 panels.

Each Brock PowerBase YSR XD shock pad measures 49 inches wide × 73.5 inches long × 0.98 inches thick (25 mm). Each pallet contains 46 panels.
