Can GSE GundSeal GCL panels be welded together like typical geomembranes?
Yes. For applications that require the geomembrane backing of GSE GundSeal GCLs to be welded, such as when it is used as a composite liner, the GundSeal geomembrane backings can be welded together at seams. The material is manufactured with protective edge tape which keeps bentonite from being attached to the length wise edges. This tape is removed after installation and just prior to welding which creates a clean edge for fusion or extrusion welding. To replace the bentonite at the seam area, a GSE GundSeal GCL seam strip is positioned under the seam which ensures continuous bentonite under the welded geomembrane seam.
