Environmental Benefits of Geosynthetics in Construction Projects

The use of geosynthetics has gained increasing attention in recent years due to their potential benefits in various engineering applications. Geosynthetics are used to improve soil structures such as base courses or retaining walls, mostly through reinforcement, filtration, separation, and sealing functions. This paper examines the environmental and economic benefits of using geosynthetics in road, earthworks, and foundation engineering. The paper discusses soil reinforcement of base courses, construction of retaining walls, and sealing layers. One of the main environmental benefits of using geosynthetics is the reduction in the use of natural or manufactured resources such as concrete. Traditional construction methods often require excavation and transportation of large quantities of soil, rock, and other materials. By contrast, geosynthetics can be used to enhance the properties of existing soils, minimizing the need for additional materials. This significantly reduces the carbon footprint and improves the sustainability of construction projects. Case studies are presented to illustrate the benefits of geosynthetics in practice. The paper concludes that geosynthetics can provide significant environmental and economic benefits in construction and should be widely considered in construction projects.
