We will introduce a long-term case study of a thin-layer tray type rooftop greening system in Chiba Prefecture.

The inspection conducted in the ninth year with the customer's consent. The greenery on the rooftop remains unchanged since the time of delivery!

In 2019, a large typhoon struck Chiba Prefecture. In September of the same year, I visited several properties where we had delivered and installed work in Chiba Prefecture for a self-inspection. Self-inspections were conducted at Store A, Store B, and Store C, all of which have metal roofs. First of all, despite hearing that maintenance had hardly been performed, the condition of the rooftop greenery at each property was good. We also conducted a self-inspection to check for any issues with the installation of the thin-layer tray-type rooftop greening system. The inspection results showed no problems. Before conducting the self-inspection, I was particularly concerned about Store A, which had been delivered and installed in 2010, as the number of years since installation crossed my mind. It has been nine years since then. The plants were growing and declining with the seasons on the rooftop, spreading their unchanging greenery towards the sky. The fixtures that hold them in place continued to support the planting trays without change. Our rooftop greening system is a non-irrigation system compatible with various metal roofs. [Case Overview] ■ Location: Chiba City, Chiba Prefecture ■ Delivery date for Store A: May 2010 ■ Delivery date for Store B: October 2013 ■ Delivery date for Store C: November 2014 I would like to express my heartfelt sympathy to all those who suffered damage from the large typhoon that struck Chiba Prefecture in 2019.
