The characteristics of blast furnace slag provide long-lasting weed control! A rich variety of colors harmonizes with the landscape!
"Glassless Sand" is a weed control method that involves spreading a pavement material made by mixing blast furnace water-quenched slag as aggregate with cement and admixtures within a formwork, and then compacting it to a specified thickness. By utilizing the latent hydraulic properties of blast furnace slag, it can sustain weed control effects in a long-term and stable manner, ensuring a good landscape and visibility, as well as preventing the occurrence of pests, thereby maintaining a comfortable living environment. Additionally, by allowing rainwater to permeate through the surface of the weed control work and return to the ground, it contributes to the prevention of global warming and the reduction of environmental impact. [Features] ■ Contributes to the sanitary environment for residents living in the area through weed control work ■ Environmentally oriented with a rich variety of color options, considering landscape aesthetics ■ Contributes to the prevention of global warming and the reduction of environmental impact *For more details, please refer to the PDF materials 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."
