Vibrations created by road or railway traffic are transmitted though soil to adjacent structures. In densely populated urban areas this can have an impact on the health and well-being of residents as well as affecting the value of their property. Geocomposite products with 3D looped filament polyamide cores have been used successfully over the world for decades in vertical and horizontal drainage applications. In situ monitoring coupled with complementary laboratory testing has led to a comprehensive understanding of the capabilities of these products, which due to the long-term elasticity of the polyamide core enables these materials to reduce the transmission of these vibrations. This paper discusses the efficiency of the geocomposite materials on the basis of newly executed field test results regarding the behaviour of geocomposite materials in dynamic pressure environment.
