PowerBase™ is made from polypropylene, a material known for it’s durability and versatility in design. It provides superior dimensional stability through temperature variations, wet, dry, and frozen conditions. The unique BROCKLock™ interlocking design ensures the panels will not move during or after your installation. Unlike other “underlayments,” or “shock-absorbing” foams – PowerBase™ will not displace turf, deform, buckle from heat or moisture, or form gaps in cold or dry conditions which can be seen through the turf. No other manufactured system on the market is free from any of these issues.
