Permeable concrete pavers deserve special mention as a sustainable construction material. These concrete pavers are specially installed to filter storm water runoff through the paver joints to base and sub-grade layers that act as natural filters by capturing many harmful pollutants. Permeable pavers are widely recognized as an effective solution for reducing total suspended solids (TSS) levels in storm water to EPA-mandated standards.

This makes them an environmentally preferable solution for a number of reasons:

  • Stormwater management - Runoff from paved surfaces can cause serious environmental damage such as erosion and silt build-up in rivers, lakes and streams. By allowing rain and snowmelt to infiltrate on site, permeable paver systems reduce or eliminate runoff problems. Permeable paving eliminates surface puddles and local flooding, and is typically required in many waterfront applications to protect fragile shorelines.
  • Groundwater recharge - With permeable pavers, a higher percentage of rain and snowmelt percolates naturally down through layers of aggregates to maintain healthy groundwater levels.
  • Pollution control - Permeable paver systems trap up to 80% or greater of TSS, including salt, oil and other pollutants in runoff rather than allowing them to wash into the local watershed where they can harm fish and other wildlife. The aggregate base and subbase system acts as a built-in filtration device.
  • Tree maintenance - Trees beautify our cities and help regulate temperature in urban areas. Trees need adequate groundwater to stay healthy. Permeable pavers promote tree survival and growth by allowing tree roots to receive the air and water they need.
  • Tax incentives - Local governments may offer tax incentives, utility fee reductions, expedited permitting or approval for demonstration projects to encourage use of permeable pavers as a sustainable best management practice.
  • Lower lifecycle costs - While permeable pavers often have higher costs initially, they don’t require the installation of underground drainage piping, and they reduce the need for continuous expansion of drainage infrastructure.
