Summary: Grasspave2 was selected as a “green” alternative for helicopter landing pads. The Pentagon RDF is the largest green roof east of the Mississippi, and Lee and Associates, Landscape Architects, needed to keep as much of the landscaped look as possible. Grasspave2 has a high compressive strength (5,721 psi) more than adequate to land a helicopter – other installations have seen jet aircraft driving over the system. The Pentagon RDF is also a LEED Certified project. Grasspave2 helped get the certification with its 100% recycled content, stormwater benefits, and heat island mitigation.
