What are permeable pavers?
Permeable pavers refers to a system of interlocking concrete pavers, installed in such a way, that allows water to filter through the gaps between the pavers to the specially prepared gravel layers and infiltrate into the ground. Conventional driveways or patios made of impermeable asphalt or concrete do not allow water to pass through and direct stormwater toward storm drains, streams, and ponds. In many areas, the amount of stormwater generated from impervious surfaces is so large that it can exceed the capacity of storm drains, resulting in localized flooding. In addition, stormwater runoff contributes to stream pollution and erosion. The replacement of conventional concrete or asphalt with permeable pavers helps to reduce these impacts.
