Preservation to ensure optimal wood protection and long-term usability
Wood that is used outdoors needs effective protection against fungi and insects. This is the only way to ensure its durability and cost-effectiveness. We impregnate in industrial plants, using different methods depending on the application. We have decades of experience in using impregnating agents, both from renowned manufacturers and our in-house test plant, according to the latest technology standards.
