Due to Hilton Head Island regulations, the a UPS expansion at its hub facility required a porous parking lot and road. UPS performed an internal review between porous concrete and Gravelpave2. Installation time for porous concrete was 7 to 10 days, whereas Gravelpave2 was a maximum of 3 days. Porous concrete has only 2,800 psi compressive strength and Gravelpave2 has 15,940 psi. Gravelpave2 was also a third of the cost of pervious concrete. Daily maintenance was deemed too much for pervious concrete with an entire parking area and road lined with deciduous trees.
