(2) Water: Regular tap water is sufficient. Impure groundwater that has not been filtered or used water that is not clean should not be used.

(4) Pigments: High-quality inorganic pigments

b. Fabric: When laying permeable pavement, consider the reserved compaction height. When using manual fabric for permeable pavement, use a shovel to flip over, never throw. If the laying time for permeable pavement exceeds 30 minutes or there is strong wind, cover the concrete site with plastic sheets promptly to prevent rapid moisture loss from the permeable pavement.

d. Surface Finishing: Promptly finish the edges of the compacted surface with permeable concrete. For areas with insufficient material, fill and level the surface. For drier sections, spray a layer of water evenly first, then add material for finishing.

f. Maintenance: After the surface finishing of the permeable paving, it should be immediately lightly watered and covered with a plastic film for maintenance. The maintenance period is the same as that of normal concrete. During the maintenance, barriers should be set around the road surface, and it is strictly prohibited to have pedestrians or vehicles on site.
