Influence of the degradation on the stress cracking values of high density polyethylene (HDPE) geomembranes after different exposures
(2012-12-03)
This paper presents results from stress cracking (SC) tests performed in both fresh and exposed high density polyethylene (HDPE) geomembranes (GM). The HDPE GMs were exposed to ultraviolet radiation, thermal aging (air ...

Permeation properties of HDPE geomembranes
(2010-01-01)
This paper evaluates the permeation properties of HDPE geomembranes intacts and after exposure to UV rays (weathering) after 12 years. Water vapor transmission tests (WVT) were performed in HDPE geomembranes (1.00 mm). ...
EVALUATION OF THE INFLUENCE OF DAMAGE ON THE PERMEATION AND DIFFUSION OF POLYMERIC GEOMEMBRANES
(Centro Federal Educacao Tecnologica Rio Grande Norte, 2021-01-01)
Geomembranes have been used in order to waterproof and protect the soil, as well as groundwater and water sources. However, during the installation process they can become susceptible to the occurrence of mechanical damage ...
UV degradation of HDPE and pvc geomembranes in laboratory exposure
(2010-01-01)
This article evaluates the effects of UV degradation in HDPE geomembranes that were exposed both in laboratory and outdoor conditions. The laboratory tests were performed using a weatherometer assembled at EESC-USP in ...

UV exposure of polymeric geomembranes
(Zhejiang Univ Press, 2008-01-01)
The break of polymer chemical bonds may occur due to penetration of sun short wavelengths. In sanitary landfills for instance, ultraviolet radiation affects uncovered materials and can be dangerous during the installation ...
