Permeable Stone-like PC Paver for Sponge City Projects

Product features:

This product solves the pain points of traditional permeable bricks, such as easy blockage, low compressive strength, and short service life. The open-pore litchi surface design ensures that the rainwater can quickly penetrate into the ground through the internal porous structure, while effectively preventing soil and sediment from blocking the pores. The porous aggregate formula improves the compressive strength, allowing it to withstand the trampling of pedestrians and the rolling of light vehicles. The surface texture replicates the natural stone effect, meeting the landscape design requirements of sponge city projects. It also has excellent anti-clogging performance, which can be easily cleaned by high-pressure water gun, reducing later maintenance costs.

Product specifications:

The standard size is 200mm x 400mm with a thickness of 80mm, and custom sizes are available according to customer needs. The compressive strength reaches ≥35MPa, meeting the load-bearing requirements of pedestrian and light vehicle traffic. The permeability coefficient is ≥1.2mm/s, which can quickly drain rainwater and reduce ground runoff. The skid resistance index is ≥0.7 BPN, ensuring the safety of pedestrians in rainy weather. The water absorption rate is controlled within a reasonable range, with fast drainage performance. It is available in light grey, deep grey and other colors, matching the landscape style of sponge city projects.

Product application:

This permeable paver is mainly applicable to sponge city construction projects, urban rainwater gardens, road sidewalks with rainwater harvesting functions, park green space paths, and community parking lots with permeable requirements. It is widely used in urban waterlogging control projects, low-impact development road construction, and ecological park construction. It can effectively reduce urban ground runoff, replenish groundwater resources, and improve the urban ecological environment, while creating a natural stone-like landscape effect. During construction, it can be matched with permeable base materials to form a complete rainwater infiltration system.
