JIAYE
Geosynthetic Clay Liners (GCLs) 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 JIAYE®
GCLs make the product ideal for many lining and cap containment
projects.
Primary features of the JIAYE®
GCLs:
(1)
High internal shear strength
(2) Uniform bentonite content
(3) Excellent installation durability
(4) More versatile than compacted clay
(5) Increased airspace and liner efficiency
(6) Improved leakage performance
