specific engineering goals They are not substitutes for soil or other construction materials but rather enhance their performance The main types of geosynthetics include Geotextiles Woven or nonwoven fabrics used for separation filtration drainage reinforcement and protection They are highly versatile and find applications in various projects Geomembranes Impermeable sheets primarily used for containment of liquids and gases They are essential in landfills lining canals and creating reservoirs Geogrids Highstrength polymeric grids used for reinforcement increasing the bearing capacity of soils They are frequently used in road construction and slope stabilization Geonets Threedimensional netlike structures used primarily for drainage Their high void space allows for efficient water flow 2 Geocomposites Combinations of different geosynthetics such as geotextilegeomembrane or geogridgeotextile composites that offer combined functionalities Applications of Geosynthetic Engineering
