...E. Kavazanjian; J. Andresen; A. Gutierrez Laboratory testing was conducted to evaluate strain concentrations adjacent to high-density polyethylene (HDPE) geomembrane seams loaded in tension perpendicular to the seam. Strain concentrations were evaluated using digital image correlation (DIC...

...W. Guo; J. Chu; B. Zhou Permeable geotextile tubes are usually made by sewing geotextile sheets together and then filling with clay slurry or sand. However, the tensile strength of a seamed woven geotextile material is usually only half of that of the seamless geotextile sheet. A new seam method...

...P. Pierson; M. Barroso To characterize the gas permeability of seamed or non-seamed geomembranes, laboratory tests were carried out using a new permeability test: the gas permeability pouch test. Circular and rectangular “pouches” made of two pieces of high density polyethylene (HDPE) geomembrane...

...J.P. Giroud; B. Tisseau; K.L. Soderman; J.F. Beech Polyethylene geomembranes which are subjected to excessive tensile strains often fail next to seams. The analysis presented in this paper shows that strain concentration due to geomembrane bending in the vicinity of seams may play a significant...
