The core highlight is its ultra-high water permeability of 1.2mm/min, which can quickly infiltrate rainwater from the road surface into the ground during heavy rain, effectively alleviating urban waterlogging and replenishing groundwater resources. The internal porous structure made of ceramsite aggregate not only has water permeability but also effectively reduces road noise, improving walking comfort. Its 55MPa compressive strength can withstand non-motor vehicles and light vehicle traffic, suitable for urban greenways, parking lots and other scenarios. The surface is treated with porous stone-like texture, which not only ensures water permeability but also has excellent slip resistance, with a R12 slip resistance rating ensuring pedestrian walking safety in rainy days. It is made of highly recyclable environmentally friendly materials, reducing the generation of construction waste and complying with the development concept of low carbon and environmental protection.
The standard size is 400mm×400mm×60mm, with a single block weight of approximately 7.5kg, and a water permeability rate of 1.2mm/min, complying with the GB/T 25993-2010 standard for permeable pavement bricks and permeable pavement panels. The internal porosity is over 25%, which can effectively store rainwater and slowly release it into the ground. It has a compressive strength of 55MPa, which can withstand repeated walking of adults and temporary parking of small cars. The surface is treated with porous stone-like texture, with a friction coefficient of over 0.75, and excellent slip resistance. It uses ceramsite, cement and natural stone powder as main raw materials, without any toxic and harmful substances, complying with national environmental protection standards. It is packaged on pallets, with approximately 62.5 square meters of paving bricks per pallet, which can be directly used for paving construction of sponge city projects.
It is mainly applicable to areas requiring permeable paving such as sponge city construction projects, urban greenways, community parks, parking lots, sidewalks and squares. It can be used to create urban slow-moving systems, community leisure spaces, paving floors around rainwater gardens, and effectively coordinate with landscape greening and rainwater collection systems, contributing to urban ecological environment construction. Its porous structure can also effectively reduce road temperature and alleviate urban heat island effect, creating a more comfortable outdoor environment for cities.
