The main field of economic activity of our company is civil engineering construction, that is, conducting works on construction, reconstruction, and maintenance of all types of roads, in accordance with the international standards ISO 9001, 14001, 45001, and 50001. In 2005, we obtained the licence I131G2 for performing works on national roads of the Class I and II, road facilities, and border crossings, for which a permit is issued by the competent ministry. We proudly emphasize our long experience and a series of successful projects from this field, which have made us recognizable and which have been associated with the name of our company from many years.
For many years, apart from our primary activity, we have been successfully dealing with works in the field of hydro-construction, resulting in numerous successfully implemented facilities for the construction of water supply and sewage networks. We have constructed and reconstructed more than sixty kilometres of water supply and sewage networks, with accompanying water treatment and management facilities. Considerable investments in hydrotechnical equipment enabled us to readily welcome every project and to respond to all requirements of both the profession and investors.
Put-invest owns a modern asphalt base plant near Novi Sad and all larger towns in Vojvodina, which is one of the largest asphalt bases, with production capacity of up to 3,000 tons of asphalt mass per day. Its performance completely meets the needs of even the most demanding facilities, such as the construction of large highway sections and roads of particular importance. Owning asphalt production ensures uninterrupted supply of construction sites with asphalt mixtures during the implementation of the most complex projects, which is essential for the quality of the roadway structure. The asphalt base also has a system for the production of asphalt with the addition of recycled asphalt mixtures. The plant is equipped with modern ecological filters of the latest generation. The quality control of the input raw materials for the production of finished and installed asphalt is performed by accredited laboratories that monitor and control our production process.
