In 2009 with PowerBase PLAY, Brock introduced a new level of engineering, precision and consistency to playground surfacing. When combined with a quality infilled artificial turf surface the playground becomes more natural looking, lasts longer than poured in place systems, and most importantly, produces consistent long-term impact performance. An artificial turf surface system with PowerBase PLAYPlayground surfaces with fall height safety requirements up to 9 feet according to the ASTM F1292 standard specification. The PowerBase PLAY system is dimensionally stable, provides consistent impact attenuation through temperature changes, is highly permeable, has the highest hydraulic lateral transmissivity rate of any playground underlayment system and can retain up to 1” of water within its underside 3-dimensional impact absorbing structure.PowerBase interlocking panels are multi-functional shock absorbing, vertical and lateral drainage base systems that can be installed over permeable or impermeable sub-base constructions. Each PowerBase system installs quickly and precisely without the need for tapes or glues. Each PowerBase panel is individually molded from high grade recyclable expanded polypropylene (EPP) in the USA in an ISO certified facility. All PowerBase systems are Cradle to Cradle Certified, a comprehensive product quality standard that evaluates product design, manufacturing and sourcing practices as well as corporate citizenship and ethics principles. C2C Certification is a symbol of Brock’s commitment to environmental stewardship and social responsibility. Cradle to Cradle Certified is also integrated as a key element of the LEED V4 Green Building Program.
