SUPBENT EG Geosynthetic Clay Liners are high performance needle punched environmental reinforced composites which combine two durable geotextile outer layers with a uniform core of natural sodium bentonite clay to form a hydraulic barrier. Fibers from the non-woven geotextile are needle punched through the layer of bentonite and incorporated into the other geotextile (either a woven or non-woven). Unique properties, including increased internal shear resistance and long-term creep resistance result from this production.　　When hydrated under a confining load, the bentonite swells to form a low permeability clay layer with the equivalent hydraulic protection of several feet of compacted clay. The excellent hydraulic properties and slope performance of the SUPBENT EG make the product ideal for many lining and cap containment projects.
