New Types of Geo-Composite Materials for Anti-Filtration Systems

Abstract

The article discusses the results of studies of new types of geocomposite materials used for anti-filtration and drainage purposes in hydraulic engineering and environmental protection construction. As the main elements, the presented geocomposite materials include various types of synthetic materials – bentonite mats and profiled geomembrane. A distinctive feature of these materials is the inclusion of additional elements of geotextile material or polymer geomembrane in their design, these elements are connected to the main element by thermal bonding. As a result, the combined geocomposite materials acquire new properties: they become more waterproof and durable. At the same time, waterproof materials are used for anti-filtration systems (as screens and coverings for canals, ponds, dams and various types of waste collectors), and previous material are used for drainage systems (as drainage in hydraulic and civil engineering). New types of geocomposite materials have improved properties on water resistance and water permeability (filtration coefficient), durability and strength.
