Jazan City in Saudi Arabia is characterized by steep mountainous terrain, winding roads, and significant elevation changes. Due to the natural geology, fractured rock formations, and steep slopes, the area is highly susceptible to rockfall hazards, particularly during periods of heavy rainfall and temperature variations. These rockfalls pose a serious risk to public safety, road users, and nearby infrastructure, potentially causing traffic disruptions, property damage, and accidents. Existing protective measures are limited and do not provide adequate long-term mitigation against increasing rockfall events. Therefore, the authorities are seeking reliable, durable, and proven rockfall protection solutions that can be effectively installed in challenging mountainous conditions, minimize maintenance, and ensure long-term safety. Maccaferri’s engineered rockfall protection systems are considered a suitable solution to mitigate these risks while preserving the natural landscape.

Etihad Rail is the national railway network of the United Arab Emirates (UAE). From the border of Saudi Arabia to the border of Oman, this railway network will span 1200 km across the UAE. The UAE railway will connect all major import and export points, as well as trade, industry, manufacturing, production, logistics, and population centers. There have been two stages in the construction of Etihad Railway. Ruwais, Habshan, and Shah are connected by Stage One, which began operating in January 2016. This second stage has now been completed and extends from UAE-KSA border at Ghweifat to Abu Dhabi, KIZAD, Khalifa Port and Jebel Ali Port, Dubai, Sharjah, Ras al-Khaimah and then to Fujairah on the east coast of the UAE. Etihad Rail's connection to Fujairah passes partially through the Hajjar mountains, characterized by deep valleys, wadis, and high mountains. The railway works in this region required extensive mitigation solutions for problems such as scouring, erosion, soil retention and rock falling.

Siargao Island in the province of Surigao del Norte is known to be the Surfing Capital of the Philippines. Not just for surfers, Siargao's fascinating natural beauty captivates both local and foreign tourists. However, some areas are susceptible to landslides and other natural hazards due to the geologic setting and weather conditions. Certain sections of the road is confined by cut-slopes along its perimeter which is unprotected and presents the following risks: (1) erosion of soil – leading to slippery roads, (2) dislodgement of rocks leading to rockfall events, and (3) localized slope failure from surfacial instability. Even small rockfalls, or debris flows can block infrastructure and can have far-reaching economic effects beyond the immediate disruption.
