4S, based in Olbia but also operating in Arzachena, Golfo Aranci, and Porto Cervo, carries out excavations and demolitions using the latest available technologies. We utilise state-of-the-art excavators, both wheeled and tracked, to perform work on all types of terrain and in any weather conditions. Thanks to our fleet of lorries for transporting sand and rubble, we can clear the worksite quickly. We operate in Northern Sardinia, primarily in Olbia and the surrounding areas.
