"PERMEABLE PAVERS"

End Grain Flow Pavers, are naturally rot-resistant wood blocks attached to a recycled backing to create an easy to install wood walkway at ground level or for rooftops. The end grain of the wood is stronger than concrete. Black Locust wood pavers are naturally rot-resistant for a lifetime of 50 years or more. Rainwater is able to pass through the paver joints and natural bio filters, for maximum water filtration. While permeating through each filter, the water quality is improved and runoff pollution is reduced. Black Locust permeable pavers help restore groundwater resources and reduce the heat island effect
