stress prior to hydration, damage resistance, interface shear strength, durability, overlap sealing, the potential need for a polyolefin coating, and much more. Safety, of course, is of the utmost importance. Geosynthetic Clay Liners (GCLs) are often used as a stand-alone liner or in combination with a ge-omembrane. They replace thick compacted clay liners due to many advantages, such as easy installation, low hydraulic conductivity, self-healing capabilities, capable of withstanding [...] layer (fig. 1), securing the bentonite in place and reinforcing the oth-erwise weak layer of clay (when hydrated). The carrier layer is either a woven or a combination wo-ven/nonwoven geotextile which allows for good anchorage of fibres (von MAUBEUGE et al., 2007). The main purpose of a geosynthetic clay liner (GCL) is to reduce/limit the flow of liquid through the GCL or barrier system. GCLs are mostly used to replace a compacted clay liner (CCL) or soil barrier. Multi-component geosynthetic [...] Poor selection or installation can have the effect of negating the economic and technical benefits. This paper will touch mainly used geosynthetic systems but focus mainly on geosynthetic clay liners (GCLs) and the recent development of multicomponent GCLs. Geosynthetic clay liners (GCLs) are mostly needle-punched, fibre-reinforced composites that combine two durable outer layers and an intermediate uniform core of high swelling powder sodium bentonite clay, which acts as the barrier component.
Geosynthetic clay liners (GCLs) represent a relatively new technology (developed in 1986) currently gaining acceptance as a barrier system in municipal solid waste landfill applications. Federal and some state regulations specify design standards for bottom liners and final covers. Alternative technologies are allowed, however, if they meet federal per-formance standards. GCL technology is an alternative that performs at or above standard federal performance levels. GCL technology offers some [...] 1EPA United States Environmental Protection Agency EPA530-F-97-002 Revised December 2001 Solid Waste and Emergency Response (5306W) Geosynthetic Clay Liners Used in Municipal Solid Waste Landfills GCL Technology Materials A GCL is a relatively thin layer of processed clay (typically bentonite) either bonded to a geomembrane or fixed between two sheets of geotextile. A geomembrane is a polymeric sheet material that is impervious to liquid as long as it maintains its integrity. A geotextile is a [...] Bearing Capacity A study by the Geosynthetic Research Institute provides the basis for allaying some concerns about the bearing capacity of hydrated GCLs, but more research is needed. The study demonstrated that an adequate layer of cover soil (according to the product manufacturers’ recommen-dations), placed on GCLs during installation, prevents a decrease in liner thickness with the application of a load. Without a sufficient soil layer, GCLs become compressed, raising their hydraulic
