The Retaining Wall Structure for Stilling Basin in Sadawarna Dam is constructed using Paramesh System with a height of 5m, consisting of the Terramesh System as the facing and secondary reinforcement, which is then combined with Paragrid HF 150 – geogrid with a tensile strength of 150 kN/m – with the length of 3m – 5m as the primary reinforcement of the structure. Maccaferri Indonesia proposed to use the Polimac Coated Wire for the Terramesh System as protection against corrosion, abrasion, and UV exposure. The usage of this material proved to be more effective and efficient in terms of construction time and cost. All the stability checks of the structures were performed using the internally developed software of Maccaferri (MacStars). Furthermore, Maccaferri provided the client with Product Assistant in order to ensure The Obligated Standard

Procedure was followed.
