Geomembrane welding procedures and imperviousness assessment

Abstract

This paper presents the main geomembrane welding procedures used in the sealing systems. The causes leading to inefficacious welding of sheets are studied and the procedures currently used for welds are presented. The paper also includes the advantages and downsides of each procedure, by the type of geomembrane and by the technology used for these works. In addition, the article outlines the assessment methods for welds executed on sites (for quality control goals).
