Abstract

The present invention makes a water-permeable structure decorative, to enhance landscapes such as streets. In a water-permeable structure 10, gaps among aggregates 21, 31 act as water passages. The water-permeable structure 10 is divided into a base layer 20 that forms a main part and a surface layer 30 that covers the surface of the base layer 20, and the aggregates in the surface layer 30 are formed of dry gravel that is natural stones. The respective aggregates 31, 21 of the surface layer 30 and the base layer 20 are hardened with an epoxy resin binder that is mixed with ceramic fibers or glass fibers. The water-permeable structure is installed on a rainwater retention layer that is formed of crusher run laminated on a roadbed, thereby configuring a water-permeable pavement structure. The water-permeable structure is filled inside an edge frame, thereby configuring a water-permeable lid for drainage facilities.
