Geosynthetic liner: A modern solution for a concrete dam constructed from particularly lean roller-compacted concrete

Abstract

This paper discusses the issue of seepage control in gravity dams made of compacted lean concrete. Several possible design options are outlined. The benefits of using geocomposite impervious blankets are explained. A description of different types of geocomposites is given, including their composition and component parameters. Basic properties of geosynthetics are discussed, along with methods for defining them, such as water permeability, tensile strength, puncture resistance, and ageing. Finally, the main areas for future research are formulated, although it may be helpful to provide more detail on the specific focus of this research.
