[Case Study] Glassless Sand (Reconstruction of Street Trees in the Nishizukuma Area along National Route 3)
Reduce weeding effort and cut costs! Introducing examples of the weed prevention method "Grassless Sand."
At the Fukuoka National Route Office of the Kyushu Regional Development Bureau of the Ministry of Land, Infrastructure, Transport and Tourism, our environmentally friendly high furnace slag weed control method "Grassless Sand" has been adopted as a weed control measure for the planting area in the "National Route 3 Nishizukuguma District Street Tree Reorganization" project. Before the maintenance, the area was overgrown with weeds, and the sidewalks were narrow, making pedestrian movement difficult. However, with this maintenance, a neat landscape has been secured, the effort required for weeding has been reduced, and it has also led to a decrease in maintenance costs. 【Benefits of Adoption】 ■ Two-layer structure shuts out weed growth ■ Stability of slopes through formwork connection method ■ Excellent permeability and water retention ■ Maintenance of long-term durability ■ Use of materials resistant to freeze-thaw cycles in winter *For more details, please refer to the PDF document 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."
