Porous pavement

Porous pavement, also known as permeable pavement or pervious pavement, can consist of cast-in-place pervious concrete, or porous asphalt pavement. Residential porous pavement typically consists of interlocking concrete pavers (such as brick pavers or block pavers) that have built-in gaps or openings through which rainwater and stormwater runoff can infiltrate.

The purpose and concept behind porous pavement is to provide stormwater retention (soaking runoff back into the ground). Depending on the subsoil infiltration capacity, porous pavement can help to maintain the natural water cycle, recharging local aquifers and supporting groundwater-driven base flow (subsurface water movement) that feeds into streams, ponds and wetlands. Porous pavement systems can also improve runoff quality through filtration and a reduction in runoff temperatures (thermal loading).

In 2003 we started bit by bit to remove the old, impervious, cast-in-place concrete pavement and side walk (a run-of-the-mill sidewalk) and replaced it with the porous pavement. All of our concrete pavers were salvaged from various locations before being reused in this project.

You can download an INFO SHEET for more detailed information on porous pavement and its performance in freezing climates. Additional information on winter maintenance/snow clearing is included in the SNOW VIDEO and SNOW MELT+ICE section and WINTER IMAGES.
