• Pile and foundation work

When weeds proliferate around power facilities, small animals such as "snakes" and "birds" inhabit the area, which can lead to their intrusion into electrical equipment, damage to control cables, and cause electrical accidents. Additionally, when weeds grow abundantly within a solar power plant, it can result in decreased power generation and malfunctions or failures of power converters. However, areas close to power facilities are often fraught with dangers. Tōsō Kōgyō Co., Ltd. has many employees with backgrounds in power companies. Because our company is well-versed in power facilities, we can safely carry out tasks from weeding to cleaning.
