A proposal for a comfortable eco-life that is environmentally friendly through rooftop greening!
At Shirokaze Juken Co., Ltd., we are engaged in rooftop greening using the evergreen giraffe grass bag method in various facilities, buildings, and residences. The standard size is 50 cm square, with soil thickness of about 4 cm to 5 cm inside the bag, which grows solely with rainwater and does not require irrigation. With a load of approximately 40 kg/m², it can easily green existing buildings, significantly contributing to maintenance reduction through weed control, and efforts are made to minimize waste during the manufacturing process and on-site work. The "evergreen giraffe grass bag method" addresses the issues of rooftop greening. Please feel free to consult us. 【Features】 ■ Easy to handle due to the bag method ■ Simple seedling placement ■ No irrigation required ■ Easy installation ■ Prevents weed intrusion *For more details, please refer to the catalog or feel free to contact us.
