Xeripave Natural Stone Permeable Pavers

Rancho cucamonga dogpark

Stormwater design and control is a huge aspect of green building, especially with LEED credits provided for reducing impervious cover, increasing on-site filtration, and reducing pollution from stormwater runoff and eliminating contaminants.  We've mentioned a company previously makes recycled content pavers, Vast Pavers, but I thought I would also mention another company that's been making news in the industry, Xeripave.  Xeripave makes permeable pavers in various colors that have a flow through rate of up to 1.5 gallons per second per square foot.  Watch how the paver works:
