Pervious concrete is an innovative building material with many environmental, economic, and structural advantages. By allowing for various size voids in the concrete, Filtercrete allows water to pass through, putting rainwater back in the ground. Property owners and developers can also reduce fees and enhance the bottom line by using Filtercrete, which can provide 20-40 years of low-maintenance performance. Filtercrete also has a wide array of applications, ranging from streets and alleys to residential and architectural use.
The surface of a parking lot is heavily littered with trash, car oil, and chunks of asphalt. This junk is eventually swept away by stormwater that drains into retention ponds. From there, it flows into our local bodies of “fresh” water.
Filtercrete prevents these pollutants from contaminating out rivers and lakes because the concrete itself absorbs the stormwater, eliminating the need for retention ponds.
As the stormwater drains through Filtercrete, it is absorbed, filtered, or colonized with natural microbes that consume the pollutants.
Through this process, Filtercrete simultaneously purifies the stormwater and eliminates the need for expensive stormwater maintenance solutions.
Lowering Heat Island Effects
Cooling down “urban heat islands” can significantly reduce smog. Ozinga’s Filtercrete can help fight these rising temperatures in several ways.
The voids in Filtercrete allow water in the ground to evaporate (evapotranspiration) and cool the air above the ground. And lighter than black asphalt, Filtercrete also absorbs less heat from the sun. Because air and water move freely through the gaps in the concrete, trees can grow as closely as one foot away from Filtercrete. The shade from these trees helps stifle rising temperatures.
While Filtercrete protects the environment by filtering water and cooling the air, cities can lower pollution levels and reduce air conditioning costs.
During the day, dark asphalt and building facades absorb light from the sun, turning it into heat and raising ambient temperatures in dense urban areas.
By the time the sun goes down, the heat that was absorbed into the asphalt and buildings is finally released, raising nighttime temperatures higher than they normally would be. This is the essence of the Heat Island Effect.
Installing pervious concrete requires a special certification and it is recommended that hands-on experience with the substance be obtained before placing. Ozinga offers NRMCA pervious concrete certification classes and Filtercrete demonstrations on a regular basis – contact us to learn more and sign up for our next class.
