Traditional cement and asphalt pavements cannot retain rainwater, but this will be completely changed with the use of some eco-permeable materials.”Porous concrete, during rainy weather, allows rainwater to seep through the pavement cracks and infiltrate into the underlying strata, where it can be stored for a period of time.“Summer heat rises, and when standing on it, one can distinctly feel the difference in humidity and temperature compared to other surfaces – this is the sponge effect.

① Increase the permeable and breathable areas in cities, enhance the heat and moisture exchange between the ground surface and air, regulate the urban climate, lower the surface temperature, and benefit in alleviating the "urban heat island" phenomenon.
②Maximize the use of rainfall and snowmelt to increase the surface humidity, replenish the increasingly depleted groundwater resources in urban areas, and utilize permeable roadbeds as "reservoirs"; improve the living conditions for urban surface vegetation and soil microorganisms, and adjust the ecological balance.

③ Alleviates the burden on road drainage systems during the rainy season, significantly reducing the pollution of urban water bodies from heavy rains.
④ Absorbs noise generated by vehicle movement, creating a quiet and comfortable living and traffic environment; prevents road surface water accumulation during rainy days and glare at night; enhances the comfort and safety of vehicle and pedestrian traffic.
⑤ Prevents surface water accumulation and road reflections at night, thus avoiding the formation of black ice on the road during winter (a nearly invisible thin layer of ice formed by frost and fog, extremely dangerous), enhancing the comfort and safety of vehicle and pedestrian traffic.
⑥Large voids can absorb urban pollutant dust, reducing dust pollution.

Porous concrete flooring material is a high-quality paving material that effectively replenishes groundwater and alleviates the urban heat island effect. Its technology boasts strong practical performance and high environmental value, conducive to the benign development of the human living environment. It holds special significance in rainwater management and water pollution prevention. Currently, the technology of porous concrete flooring is an advanced and environmentally friendly technology in China, and it is a "Key Promoted Project of Scientific and Technological Achievements in National Construction."
