[Patent Granted] A vehicle-compatible pedestrian pavement material that combines excellent water retention and durability. It demonstrates outstanding long-term strength (durability)!
A new paving material that combines single-sized crushed stone and porous-shaped blast furnace water-quenched slag, possessing robustness, durability, water retention, and permeability. The interlocking of aggregates with different particle sizes achieves a bending strength of 40 kgf/cm². The "latent hydraulicity" of the blast furnace water-quenched slag provides excellent long-term strength (durability). 【Features】 ■ Bending strength exceeds 40 kgf/cm², achieving an exceptionally high value among pedestrian paving materials. ■ High durability is exhibited due to the interlocking of aggregates and the "latent hydraulicity" of the blast furnace water-quenched slag. ■ At a thickness of 7 cm, it stores approximately 16 liters of water per square meter! ■ Quickly permeates rainwater, making it difficult for puddles to form, allowing for comfortable walking even during and after rain. ■ Mitigates the heat island effect. ■ Enriches groundwater and stimulates plant growth. ■ The fine surface texture makes it slip-resistant when wet, providing easy walking. <Examples of Use> Building exteriors (terraces) / Residential exteriors / Schools / Parking lots / Commercial facilities Urban parks / Housing exhibitions / Parking areas and roadside stations / Event spaces, etc. *For more details, please contact us or download the PDF.

Company information
The permeable and water-retaining pavement materials developed by Sanwa Grand Co., Ltd. allow rainwater, an invaluable water resource for the Earth, to permeate and be returned to the ground, thereby alleviating the "heat island phenomenon" in urban areas during the summer, reviving spring water, promoting the growth of trees and flowers, and regenerating "moisture of water and greenery" in the city, creating a pavement that is friendly to both people and nature. Our company aims to contribute to society as a member of a company that creates a comfortable environment through the dissemination of these environmentally friendly pavement materials, which excel in permeability and water retention. Our pavement materials are also ideal for areas with high social needs, such as "barrier-free," "disaster evacuation routes," "weed control measures," and "school route maintenance."
