Dive Brief:

• Concrete panels that interlock and provide drainage between pieces offer a permeable paving option for sidewalks or areas with low vehicular traffic.
• The voids between the panels are filled with small stone, and the panels themselves are laid on a base of coarse stone that promotes drainage through it to lower compacted bedding sand or coarse aggregate.
• The pavers can work for pedestrian traffic areas or ones with light vehicular traffic.

Dive Insight:

According to a trade group, the permeable pavers can be installed for between $6 and $10 per square foot, which is balanced against the reduced expenses for dealing with all storm runoff though a conventional system.The pavers also come in colors and can be used as part of the design of the area.
