Porous pavement, as a new environmentally friendly and ecological road material, has garnered increasing attention. Modern urban surfaces are predominantly covered with reinforced concrete buildings, which can be widely used for various types of roads, squares, gardens, parks, public parking lots, pedestrian paths, residential communities, garden walkways, villas, garden roads, scenic roads, recreational paths, recreational squares, garden roads, ancient-style architectural clusters, and various functional roads.

Porous concrete flooring installation

a. Subgrade Treatment: Clean the subgrade surface, ensuring it is free of dust, twigs, paper屑, and other debris, and moisten the surface before laying.

b. Fabric: When laying permeable paving, consider the vibration compacted reserved height. When using manual fabric for permeable paving, use a shovel to flip it over; throwing is strictly prohibited. If the laying time of permeable paving exceeds 30 minutes or during strong wind conditions, cover the concrete on site with plastic sheeting to prevent rapid evaporation of the paving's moisture.

c. Compaction: After the plain color permeable flooring fabric is completed, it is leveled with a trowel and compacted using a flat vibratory tamper. Once compacted, lay the surface layer of colored permeable flooring or colored aggregate permeable concrete, then level it. Promptly add materials to any shortages, and use specialized permeable flooring equipment for surface compaction and leveling until it is flush with the formwork.

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

e. After the permeable concrete reveals aggregate and the surface is smooth and compact to the required standard, apply a uniform coating of cleaner to the surface and then cover it with plastic film. After 6-8 hours (depending on weather conditions) post application, use a high-pressure water jet to rinse the surface. Ensure the cleaner is thoroughly cleaned off without any debris falling off.

f. Maintenance: After the surface of the permeable paving is finished, it should be immediately lightly sprinkled with water and covered with plastic film for maintenance. The maintenance period is the same as that of normal concrete. During the maintenance period, barriers should be set around the road surface, and it is strictly prohibited for people or vehicles to enter.

Porous concrete pavement materials are eco-friendly, high-permeability materials used in sponge city construction. They serve as a novel paving method that can partially replace urban paved surfaces, offering a new approach to urban ecology. These materials breathe life back into the city's surface, allow rainwater to infiltrate the ground, effectively eliminate surface water accumulation, and are a green, environmentally friendly ground material that breathes.
