FZ/T 64036-2013 Sodium bentonite water resistant geosynthetic clay liner
1 Scope
This standard specifies the terms and definitions, classification and designation, requirements, test methods, inspection rules as well as marking, packaging, transportation and storage of the sodium bentonite water resistant geosynthetic clay liner.
This standard is applicable to the sodium bentonite water resistant geosynthetic clay liner (GCL for short) produced by needle-punching method, needle-punching film-coating method and adhesive method, which is used in waterproof and anti-seepage projects in the fields of environment, water conservancy, transportation, construction and other fields.
This standard is not applicable to the sodium bentonite water resistant geosynthetic clay liner used with seawater.
