An interdisciplinary branch of geotechnical engineering related to the manufacturing of polymer-based of synthetical materials and their applications in civil engineering projects is referred to as geosynthetic engineering. The main aim of geosynthetic engineering is to provide potential stability in terms of reinforcement, separation, filtration, and drainage. The most common types of geosynthetics are geotextiles, geogrids, geonets, geomembranes, geosynthetic clay liners, geofoam, geocells, and geocomposites. They are used for different applications like transportation, hydraulic, geoenvironmental, erosion control, sediment control, retaining structures, roads, railways, embankments, dams, landfill liners, and mining operations. This book is a compilation of chapters that discusses the most vital concepts and practical applications of geosynthetic products. It elucidates new methodology and their applications in the multidisciplinary domain. This book aims to equip students andexperts with advanced topics and upcoming concepts in this area.
