The Black Sea Region of Türkiye has a climate characterized by heavy rainfall throughout the year. This situation causes serious geotechnical and drainage problems, particularly in highway infrastructures constructed on mountainous and steep terrains. Similarly, along the Devrekani–Çatalzeytin route in Kastamonu province, intense rainfall endangered the safety of the road platform, creating the need for a retaining system in order to widen the roadway platform. The weak ground conditions in the area, combined with the reduction in bearing capacity due to rainfall, made the implementation of permanent stabilization systems essential. The aim of the project was to ensure the long-term safety of both the highway platform and the existing infrastructure, while also widening the road platform. Within this scope, a retaining system that is environmentally compatible and capable of exhibiting high flexibility was required. Maccaferri’s Terramesh retaining wall solution was evaluated as an ideal system to meet these requirements. In the project, stepped modular wall types with varying heights were implemented, resulting in a system that is both aesthetically pleasing and durable. Ultimately, the project aimed to control ground movements in the area and provide a long-lasting roadway solution.

The 12,000-year-old town city was flooded during the Hasankeyf Dam process. Before it was destroyed, all historical and cultural artifacts were moved from in the Batman district to the new Hasankeyf Cultural Park area through a special technique to preserve and transfer history, environmental and cultural values to future generations. Within the scope of the Hasankeyf Archeopark Project, which is located in the Mesopotamian region and contains many types of artifacts, stability problems became evident during the slope excavations on the banks of the Tigris River. Hence, it was decided to support these slopes with retaining walls. Since the rising of the river waters depending on the seasons and the retaining walls being under water, instead of classical retaining walls, alternative systems which has self- drain speciality is being turned forward.

The Korca - Erseka Road project is located in the southeast of Albania. The project construction started in March 2021 and finished the first part in January 2022. Currently, the road axis Korca-Erseka has a length of 45 kilometers, while with the completion of the new segment the distance is reduced to 35 kilometers. Its construction will promote the further development of tourism in the southeast of the country by bringing closer two areas with great potential, such as Korca and Erseka. With its completion, the distance between Korca and Erseka is reduced to 20 minutes. Being an unique design with back to back earthed filled structures, the contractor company ANK asked Maccaferri for our support for these project. After runing the profiles in Macstars 4. 0 we found out that the geogrid reinforcement lengths weren’t satisfying the stability checks. cks.
