Bright and comfortable walkways even on rainy days! Introducing examples of the use of permeable and water-retaining paving material "Color Sand."
The walking path along the "Shakujii River" in Tokyo has adopted our permeable and water-retaining paving material, "Color Sand." Before the installation, when it rained, many people walked on the roadway due to poor footing, raising safety concerns. After the installation, even when it rains, puddles do not form, allowing for comfortable walking. As a result, the number of people walking on the roadway has decreased, which has pleased the local government officials. 【Benefits of Adoption】 ■ Disperses direct heat, reducing glare even on hot days ■ The surface has fine bumps, making it less slippery even in the rain ■ No water splashes, making it easy to walk on even when the surface is wet ■ Provides a soft walking sensation, reducing strain on the legs and back ■ Color options that harmonize with the surrounding landscape can be chosen *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, 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."
