Project Profile:

Pentagon RDF and Pentagon Building- LEED™ 2.0 Certified

Project 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 (15,940 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.

Project Gallery

Grass pavement was installed for parking helicopters at the Pentagon RDF and Pentagon Building in Arlington, Virginia, using Grasspave2.
An aerial shot of the RDF facility. The four grass squares in the middle of the photo are Grasspave2 heliports. Helicopters land on the concrete pad, the small pentagon shape with the “H,” and hop over to the Grasspave2 pads for parking.
Porous grass pavers were used to construct four heliports for parking helicopters at the Pentagon RDF and Pentagon Building in Arlington, Virginia, using Grasspave2.
A closer look at the Grasspave2 heliports, before final renovation. Some modifications were done after this photo was taken. See final version in photo 1.
