Sodium Geosynthetic clay liner -OF

Geosynthetic clay liner-OF

Sanderay^®GCL-OF,Bentonite sometimes has been impacted by Wetting/Dry circle if it is exposed to air or soil. Sanderay^®GCL-OF is coated at least 0.15mm HDPE onto the Sanderay^®GCL-NP, which has lower permeability, usually is applied in Pond, dam, road embankment,tunnel which GCL expose to air or arid soil . PE film liner will reduce the impact of wetting/dry circle.
