As one of the main components in the construction of a sponge city, permeable materials have attracted great attentions. In this study, a series of epoxy resin water‐permeable bricks were prepared by using scrubbed and the roasted sand with different particle sizes at ambient temperature. Considering the balance between mechanical properties and water permeability, the optimal vibration time during preparation was determined. Many tests were carried out for various samples. The results indicated that there were great differences in the mechanical properties between the two types of sands. However, the water permeability rate and water filtration efficiency showed opposite tendencies for the changes in sand particle size. The value of the water‐retention rate and the anti‐slide property were 0.25 g/cm 3 and BPN (78 ± 2), respectively, which satisfied the relevant industrial standard. The adhesive coating thickness on the sand surface in the permeable material was estimated by TGA test.
