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:
These pavers can be used in conjunction with other materials, such as brick and concrete. Custom colors and sizes can be arranged, although the standard sizes are 11.81" x 11.81" x 1.97" or 15.75" x 15.75" x 1.97".
Xeripave Permeable Pavers are safe, non-slip, and strong enough for low traffic, low speed areas. Also, since they offer a high permeability rate, you may not need to cover the entire hardscape with the material. You can capture all of the runoff with something like 12-15% coverage. See how this works on a residential driveaway for a home that obtained LEED Platinum certification.
