Powerbase is a rigid, load spreading panel. It is manufactured from 100% ARPRO™ Expanded Polypropylene. This Code 5 PP is the same 100% non toxic material as Tupperware; there’s no leaching, off-gassing or contaminants. The material is fully recyclable and re-usable. The panels, with an in-molded self locking system, are manufactured through steam chest moulding. This manufacturing process is completely non toxic. Brock Powerbase is resistant to fungi, bacteria, chemical liquids, oxidation. PowerBase has achieved the Cradle to Cradle (C2C) Certification. Brock PowerBase has specifically been engineered as a shock absorbing and drainage base system for sports fields with synthetic turf. It is both a vertical and lateral drainage system and functions as an effective insulator. The material retains its dimensional stability under temperature variations, and wet, dry and frozen conditions. Suitable for indoor as well as outdoor usage.
