Maccaferri MacRO Active and Passive Protection system to mitigate the rockfall hazards in Puerto Princesa – El Nido road
One section of the road in Palawan was identified to be susceptible to erosion and falling boulders. DPWH and Maccaferri Philippines addressed this problem by providing a solution to mitigate rockfall hazards, ensuring the safety of the people passing the road.
El Nido, Palawan, is considered one of the best island destinations in the Philippines and in South East Asia, known for having incredibly beautiful natural seascapes and landscapes and one of the most biodiverse islands in the Philippines. Situated at the northern tip of Palawan island, It can be accessed by flying to the island-capital, Puerto Princesa, and riding a minivan for five hours on a windy and bumpy road. However, one section of the Puerto Princesa – El Nido road was found to be at high risk from falling boulders.
Maccaferri MacRO Active and Passive Rockfall Protection system was chosen by the Department of Public Works and Highways as the solution to mitigate the rockfall hazards. The slope of 150 meters high and 45 degrees inclination was installed with a rockfall barrier having an energy capacity rating of 1,000 KJ (RB 1000) 20 meters above the toe of the slope. Below the barrier, a Steel Grid HR30 active protection system with MacMat 12.1 erosion mat was installed to prevent boulders from detaching and to address the erosion at the bottom of the slope. Further, the contractors of the project, a joint venture of Grace Construction and JB Konstruktura, was elated with Maccaferri’s support and assistance during the installation and commissioning of the system.
Over time, the slope started to vegetate, enhancing the beauty of Palawan Island. Tourists from all over the world can travel to El Nido, Palawan, and bask at its beauty without having to worry about falling rocks and debris along the way.
