A permeable brick production enterprises: 
 Guangdong tripod built cement works in 2000 from Australia welcomed into the world's most advanced science and permeable brick production equipment, large-scale professional production of an ecological water seepage brick and its manufacturing method, the weight with the ratio: cement: 100; water: 20-35; fine aggregate: particle size 1.25-2.5mm, the amount of 300-600; coarse aggregate: particle size 5-10mm; mineral aggregate fine admixture 0-10; organic polymer 0 -40; efficient and less agent 0-0.8; mineral aggregate fine admixture of fly ash or silica fume. The organic polymer is a vinyl acetate - ethylene copolymer emulsion or polyvinyl formal. 
 , Guangzhou Ding Jian ecological seepage brick has a larger porosity, has the following technical advantages: 
 1 helps to balance the urban surface temperature and humidity, to eliminate the heat island phenomenon, can rain can quickly penetrate the surface to replenish groundwater resources; 
 Can improve the surface permeability, water permeability, maintain soil moisture to improve the ecological balance of urban surface; absorb vehicle noise; 
 On rainy days to prevent surface water and reflective at night, to improve the comfort and safety of vehicles and pedestrians walking. 
 , Built Ling permeable brick uses 
 Widely used in urban road paving, such as sidewalks, non-motorized vehicles, motor vehicle lanes, parking and living area, Park and Plaza.
