<p>A review of 92 heap leach projects from 15 countries provides a starting point for a series of experiments, at 22 &deg;C and a vertical pressure of 2000 kPa, to examine short-term puncturing and the development of geomembrane strains that could affect longer-term ...

<p>For the last three decades, high density polyethylene (HDPE) geomembranes (GMBs) have played a crucial rule as the primary barrier in municipal solid waste (MSW) landfills. In parallel, there have been extensive investigations into the service life of HDPE ...

<p>Heap leaching is one of several leaching methods (in-situ leaching, dump leaching, pressure leaching and tank leaching) whereby metal and other ores are leached with various chemical solutions to extract valuable minerals. Commonly HDPE is used in the pad ...

<p>The behavior of heat-tacked GCL seams under cyclic wetting and drying is examined. It is shown that the transverse shrinkage behavior of heat-tacked seams was similar to that observed in previous shrinkage tests performed on unseamed GCL. It is shown that ...

<p>The shrinkage of fabric-supported reinforced geosynthetic clay liner (GCL) panels covered by a geomembrane and left exposed with no overlying soil was openly documented as a potential problem in 2005. Laboratory and field testing has been conducted in an ...

<p>Shrinkage of GCL panels in composite liners left exposed to solar radiation (i.e with no cover soil/ ballast) has resulted in significant separation between initially overlapped panels in a number of field cases reported in the literature. Separations between ...
