Introducing technical information about permeable and water-retaining blast furnace slag pavement "Color Sand"!
This document explains the differences in permeability and water retention functions between "permeable and water-retaining blast furnace slag pavement (color sand)" and "porous concrete pavement." Porous concrete pavement allows for point-based permeability, while color sand enables surface-based permeability, distinguishing it as a new type of permeable pavement that can be differentiated from conventional permeable pavements. Its advancement and novelty have been recognized, and it has also obtained a "patent." Additionally, explanations regarding "water retention performance and its effects" and "the duration of sustained permeability performance" can be viewed through external links.

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."
