Abstract: In recent years, with the increasing application of composite vertical barrier technology in pollution control, GCL composite vertical barrier technology has received more and more attention due to its excellent anti-seepage performance and high construction efficiency. It has been applied in pollution control projects in fields such as landfills, slag yards, and industrial pollution sites, achieving the goal of reducing soil and groundwater pollution and protecting the surrounding environment. The GCL composite vertical barrier technology is a new type of flexible composite vertical barrier technology. This article provides a detailed introduction to its technical principle, selection of composite anti-seepage structure materials, and construction process, further elucidating the pollution barrier mechanism of this technology, in order to enhance people’s understanding of this technology. In addition, through the introduction of engineering application cases, it is further demonstrated that GCL composite vertical barrier technology could effectively control pollution.
