1.  The primary performance factors are clay
quality, amount of clay used per unit area,
and uniformity.
 In configurations using a geomembrane, the
clay is affixed using an adhesive.
 The landfill operator should test ensure that
its hydraulic conductivity.
 Provide barrier systems with low hydraulic
conductivity.
 The quality of the clay used affects a GCL’s
hydraulic characteristics.
 In particular, a geotextile-backed GCL, with
bentonite affixed via stitchbonding provides
additional internal resistance to shear in the
clay layer.
 As primary ingredient and affixed by needle
punching to a woven or nonwoven upper
geotextile and a nonwoven lower geotextile
 Mixed with water-soluble adhesive and
bonded or stitchbonded to a woven upper
and lower geotextile.
 Mixed with an adhesive and bonded to a
blend of high density polyethylene and very
low density polyethylene.
 Installers cover the GCL with soil, the GCL
hydrates by drawing moisture from the soil.
 To install it must allow enough seam overlap
at adjoining sheets to guard against the
potential opening of the barrier systems.
