Endurance Test for South America's Largest Debris flow barrier

2 June 2017

Just one year ago, the largest mudslide guard in South America was created in several valleys in the Chosica region near Lima using 22 Geobrugg mudslide protection barriers – major earthquakes had claimed many lives in this area previously. Merely one year later, El Niño struck hard and in March, it brought the worst weather in 30 years. The north of the country was hit by floods and mudslides, resulting in many deaths. Despite the terrible misfortune that the country has suffered, the Geobrugg barriers worked extremely reliably. One of the pictures shows a barrier 55 m in length as one of four consecutive barrier levels. Two of these barriers were 95% filled with a rubble volume totaling 10,000 m3. This multi-level design meant that the potential of the construction was not fully utilized and the buildings below these barriers remained well-protected, even after the major mudslide. In the residential area, people were not seriously affected. Most importantly, the main road into the heart of the country – the Carretera Central – was not blocked in Chosica, which was invaluable at the time. We are thrilled that our solutions played a small part in making the impact of the catastrophe fairly minor in Chosica. However, our thoughts are with the thousands of people across country who are still suffering as a result of this disaster.
