The consistent Gmax and Shock Attenuation properties of the AirDrain system are major contributors to the safety of players and the reduction of concussions. Unlike traditional shock pads or e-layers, AirDrain is 1” high, has 92% air void and 100% vertical drainage. AirDrain's performance cannot be matched by any other product in the industry. The AirDrain system works on any type of prepared subbase (Compacted Aggregate, Concrete or Asphalt) or rooftop. A Rubber-Free Synthetic Turf Solutions provided for Sports Fields, Play Areas and general purpose use reduces maintenance, upkeep and cleaning the surrounding area of rubber pieces that tend to find their way off the field.
