KTV Working Drone technology has been used in an extensive facade cleaning and surface treatment project at Felleskjøpet’s historic industrial facility in Vaksdal, Western Norway. The work was carried out by KTV Group, KTV Working Drone’s Norwegian franchisee, in several phases over two years, with the aim of preserving the buildings and their historical value for future generations.
The industrial complex dates back to 1871 and developed into one of Scandinavia’s largest commercial flour mills. Among its most distinctive buildings is the monumental grain silo from the 1930s, designed by renowned Norwegian architect Leif Grung.
The facility remains an active industrial production site and represents an important part of Norway’s industrial and architectural heritage.
Extensive deep cleaning and preventive surface treatment.
Years of exposure to moisture and demanding coastal weather conditions had resulted in significant dirt accumulation and biological growth across large parts of the facility.
Using KTV Working Drone technology, KTV Group carried out extensive high-pressure cleaning and deep cleaning of most surfaces. The technology makes it possible to clean large and challenging facades without scaffolding or lifts in areas where drones are used, contributing to improved safety and efficiency.
Following the cleaning, the surfaces were treated with SelfCleaner, a preventive surface treatment designed to counteract new biological growth and help keep facades clean for longer periods.
Preserving historical value through modern technology.
The Vaksdal project is about much more than facade cleaning. It demonstrates how modern drone technology can contribute to the long-term preservation of historic industrial buildings, even at facilities that remain in active operation.
By combining thorough deep cleaning with preventive surface treatment, KTV Working Drone technology provides an effective approach to maintaining complex building structures while helping protect their architectural, historical and economic value.
From historic industrial facilities in Norway to modern buildings and infrastructure worldwide, KTV Working Drone develops technology that makes exterior maintenance safer, more efficient and more accessible.
KTV Working Drone is a Norwegian technology company specialising in drone-based exterior cleaning, surface treatment and industrial maintenance. The company develops innovative solutions for maintaining buildings and infrastructure in demanding environments worldwide.
