Floor drain, permeable pavement, porous permeable floor price factory direct: 15902111656 Miss Qiu 1, pervious concrete pavement with a water permeability, water when it rains can quickly eliminate the phenomenon of roads, squares; when concentrated rainfall can reduce urban drainage burden on facilities to prevent river flooding and water pollution. 2, color permeable pavement to prevent surface water, not reflective at night, increasing road traffic safety and comfort. 3, pervious concrete pavement permeable, enabling rapid rainwater into the ground, reducing groundwater, maintain soil moisture, groundwater and soil maintenance of ecological balance, but also to avoid the over-exploitation of groundwater caused by ground subsidence. 4, permeable pavement has a unique pore structure, which is close to the ground covered by natural vegetation in absorbing and heat storage function, adjust the temperature and humidity of urban space, ease urban heat island effect. Porosity of 5, permeable pavement larger, with a sound-absorbing effect, can reduce ambient noise. 6, permeable pavement can absorb a lot of gaps urban contaminants (such as dust), to reduce dust pollution. And ease of maintenance, just use high-pressure water washing method, you can deal with the problem of pore blockage.
