GCL sodium bentonite geosynthetic clay liner is a new type of geasynthetic material, and
it can be divided into needle-punctured GCL(GCL-NP) and needle-punctured coated GCL
(GCL-OF). GCL is a kind of bentonite seepage-proofing mat needle-punctured through
filling sodium bentonite between woven geotextile and non-woven geotextile. Among which
tiny fiber spaces can be formed to prevent bentonite particles to move to a direction. It can
form glue-type water-proofing layer to prevent water leakage. Woven geotextile of 120g/㎡f
and non-woven geotextile of 220g/ ㎡’ are applied in this kind of GCL.
Mass per unit of GCL sodium bentonite clay liner can be divided into: 4000g/㎡,
4500g/㎡,5000g/㎡, 5500g/㎡, etc. The length of the product is 30m, and the width is
6m.
