Introducing technical information about permeable and water-retaining blast furnace slag pavement "Color Sand"!
This document explains the winter benefits of "permeable and water-retaining blast furnace slag pavement (colored sand)." Not only does it function as a measure against summer heat, but its permeability and water retention capabilities also provide benefits during the winter. There is less freezing after the snow melts, and the porous structure of the "granulated blast furnace slag" used as aggregate absorbs the expansion pressure during freezing through countless voids, making it resistant to freeze-thaw cycles. Even if the retained water freezes, the durability of the surface does not decrease. Further explanations on the "effects of winter permeability and water retention functions," "suppression of the summer heat island phenomenon," and "our product lineup and examples of use" can be found through external links. 【Technical Information Introduction】 ■ Suppression of the "heat island phenomenon" in summer ■ Effects of winter permeability and water retention functions - Less freezing after snow melts - Easier snow removal - The water retention function moistens the dry winter air ■ Our product lineup and examples of use *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, 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."
