Introducing technical information about permeable and water-retaining blast furnace slag pavement "Color Sand"!
This document explains the technical basis for the "permeable and water-retaining blast furnace slag pavement (color sand)" being compliant with "universal design." The target value for slip resistance is set at BPN 40 or higher on wet surfaces, and the color sand pavement exceeds 62, thus meeting the target value. Additionally, as it is a site-cast pavement, it does not pose obstacles for pedestrians and wheelchair users, allowing for smooth curved construction, making it suitable for wheelchair users and visually impaired individuals. Furthermore, it excels in shock absorption, permeability, and water retention, with the main factors contributing to overall "walkability" being elasticity, foot feel, and slip resistance. It is stated that when selecting walking surfaces, it is necessary to evaluate overall ease of walking and running. **Features** - Exceeds the target value for slip resistance - Allows for smooth curved construction - Excellent shock absorption and soft walking sensation - Maintains permeability without creating puddles that hinder walking - Highly superior in water retention capacity and retention time due to its porous structure *For more details, please refer to the PDF materials or external link pages, or feel free to contact us.*

basic information
What is the basis for being compatible with universal design? In the field of public works, the role of pavement in sidewalks requires that the surface is slip-resistant, does not cause tripping, and does not splash water. It should be level and have appropriate shock absorption. It is also necessary for the pavement to have permeability and water retention properties to help suppress temperature increases, ensuring that it is comfortable and safe for elderly individuals, visually impaired persons, and wheelchair users. It must be "barrier-free" and consider "universal design." *For more details, please refer to the PDF materials or external link pages, or feel free to contact us.*

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, revitalizing spring water, promoting the growth of trees and flowers, and restoring "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" access, "disaster evacuation routes," "weed prevention measures," and "school route improvements."
