The pavement paved by Guangzhou Wanxin Ceramic Pervious Bricks is not only a matter of the pavement data itself, but also the support of the subgrade, the system for collecting water entering, and a series of related technologies. But at present, our technical level has not reached such a requirement.

Because the permeable brick has a good function of air permeability, the new type of permeable brick is more effective in soaking up moisture and then reaching the effect of conditioning humidity. Permeable bricks are laid in the city, as if the aerobic breathing of the city is increased, so that the entire air becomes more fresh and natural. In the long-lasting past, the streets, squares, and courtyards of residential quarters in the city were mostly paved with granite, cement, and glazed tiles.

Therefore, almost all cities are facing the same dilemma. On the one hand, urban rainwater formed on many hardened grounds cannot penetrate into the ground, and the groundwater level drops because it cannot be replaced by rainwater. And inconvenience caused by transportation, and even waterlogging due to incomplete urban drainage equipment. The occurrence of a new type of permeable brick can quickly absorb water on the surface. After the brick body is soaked, water moves between the bricks and eventually flows into the underground drainage pipe. If permeable bricks are laid on the streets of the city, even in heavy rainfall, the municipal drainage capacity can be reduced to avoid water on the road area.

In addition, permeable bricks can also absorb heat and adjust the temperature and humidity of some parts of the ground surface, which has a greater effect on alleviating the urban heat island effect. Of course, there are some shortcomings in permeable bricks. His cushion cannot use concrete cushions. Because the use of concrete cushions has lost the significance of permeable bricks, water cannot enter the bottom through the permeable bricks, and water will form. In order to make the permeable bricks permeable, fine sand is selected as the cushion layer during construction. The bricks and bricks are not bonded with mortar, but are fixed on the sand layer by the effect of kneading. This can sometimes lead to road inequality. However, there is no need to worry about the compressive strength of the permeable brick. The small size and high thickness of the permeable brick can make the compressive strength relatively high.
