It is composed of 3 levels. The upper level and the lower level are
woven geotextile and non woven textile. The middle level is
bentonite grains, which are carefully selected crude and filled in
between the two levels after special
processing. The bentonite grain in GCL made by this method does not
flow in a fixed direction. It distributes evenly and forms
waterproof layer, owning excellent waterproof effect. This GCL is a
kind of new green waterproof materials, which are widely applied in
many waterproof construction projects.
GCL can be applied separately, or combined with high density
polyethylene (HDPE).
Our GCL combines the two advantages together, not only containing
all the properties of geotextile materials, but also bearing of
double waterproof property.
