What is Pervious Concrete?

Cities all across the nation are replacing their existing public walkways with concrete. It is offering a valuable solution to an existing problem, were old outdated sidewalks and walkways have suffered the ravages of time.

A Permeable Solution

Cities all across the country are switching to permeable pavers and pervious concrete as a long-lasting solution for their outdated, worn-out walkways and pathways. Municipalities are creating durable roadways, driveways, and walking paths using permeable pavers built out of concrete. This helps minimize water runoff from rains and melting snow.

The Advantage of Permeable Pavers
Because groundwater is the main source of all drinking water in a city and town, it is essential to replenish it in every way possible. It helps deep-rooted trees and plants, and minimizes erosion.

In the past, concrete was used as an impervious surface that maximized water runoff. Since then, cities and towns have attempted to minimize water runoff that often carries away chemicals and toxic pollutants from parking lots, and paved roadways into the reservoirs, lakes and rivers.

The alternative of using permeable concrete pavers has worked as an ideal solution. When installed over a bed of gravel or sand, it can filter the water before it has a chance to percolate into the ground soil below. This has helped the environment significantly in the towns and cities that have incorporated it into their new construction projects.

Pervious Concrete
In addition to installing permeable pavers on sidewalks, walkways and pathways, cities and municipalities are also incorporating pervious concrete. This porous material has much greater porosity than traditional concrete. It has reduced the amounts of sand that allows rainwater and melting snow to drain through it, instead of allowing it to run off. It is the reduced fines inside the pervious concrete that leaves a stable pocket of air. This created void is designed to allow storm water to easily flow through the product to the sand and gravel below. Eventually it makes its way back to the groundwater table, enriching the community’s available water source.

Concrete public walkways are the ideal replacement material for traditional concrete on both vehicle and pedestrian applications. However, it cannot be used on high-speed or high-volume roadways. Because of that, municipalities and small towns are installing parking lots, driveways, sidewalks and walkways using pervious cement or permeable pavers.

A Better Solution than Asphalt
Pervious concrete is an ideal solution for discerning homeowners, designers and municipalities when looking for an attractive surface for their sidewalks and walkways. The porous pavement and other available permeable surfaces have the ability to temporarily store runoff from rain water and melting snow before it is infiltrated deep into the soil below.

There are significant benefits to installing permeable pavers and porous materials. Other than offering an aesthetically pleasing result, it helps the environment in a variety of ways. Both of these products are long-lasting solutions for homeowners, business owners, and city governments.
