Geofoam: A potential for Indonesia's soil problem II

Abstract

Indonesia is a country with a fair amount of hills and mountains. Having a tropical climate and high rainfall, landslides/slope failures are a common occurrence in Indonesia. According to the Indonesian National Board for Disaster Management, 355 slope failures occurred in 2019, with 81 casualties. To aggravate the problem, global warming and climate change result in extensive dry period and higher intensity rainfall. Slope failures can become more frequent in the near future. Common mitigation of slope failure includes construction of retaining structures, or by reducing water infiltration by the use of shotcrete. In this paper, the use of geofoam to mitigate slope failures is introduced, followed by a case study.
