The invention provides water-permeable bricks. Each water-permeable brick comprises a water-permeable brick main body and an anti-pollution coating layer, wherein the water-permeable brick main body is prepared from the following production raw materials: waste ceramic crushed grains, waste stone crushed grains, cement, sand and water; the weight part ratio of the waste ceramic crushed grains to the waste stone crushed grains to the cement to the and to the water is (20 to 35 parts) to (10 to 15 parts) to (1 to 3 parts) to (6 to 10 parts) to (3 to 10 parts); the anti-pollution coating layer isprepared from the following production raw materials: fluorocarbon coating and an organic silicon anti-pollution agent; the mass ratio of the fluorocarbon coating to the organic silicon anti-pollution agent is 1 to (40 to 80). The water-permeable bricks provided by the invention have high water permeability and also keep high-strength stability and corrosion resistance; the water-permeable brickshave an excellent water-permeable function so that a comfortable living environment is created for human beings; comprehensive utilization of wastes is facilitated, energy sources and resources are saved and real recycling economy is realized.
