This special brick is called an ecological permeable brick . It looks no different from other bricks, but when you pour a glass of water, the water disappears quickly, and the watermark left is gone for a while. Actually seeped from under the brick. It is understood that due to the large coverage of cement and asphalt, water cannot penetrate into the ground smoothly, resulting in more than 60% of the surface water lost in Chinese cities each year, disrupting the normal circulation of natural water. The implementation of this permeable brick will help deal with this problem. Inventor: In this way, rainwater can be collected thoroughly, soaked into the ground, or collected and used. The rainwater will not be left in vain with the sewer.
Now, this kind of permeable brick has been assessed by the Ministry of Construction and has been used on the Olympic site in Beijing.
