Certified and continuous development
Throughout our company’s history, we have been guided by quality and environmental responsibility. The responsibility values of a family business have always been and still are a part of our everyday operations. Quality and environmental certificates are proof of our operations, but in the name of continuous development, we want to go beyond official requirements. We are continuously investing in modern technology and reducing our carbon footprint. For example, the transition to electric propulsion for machinery and equipment has already taken a concrete shape, and for diesel-powered heavy equipment, we use myDiesel made from waste. We also require that our subcontractors operate at the same level of responsibility and quality as us. Looking to the future and continuous development is how we work and deliver sustainable services.
Kati Orasjärvi, our Director of Responsibility, is in charge of matters related to quality and responsibility.
