geosynthetic
clay liners
A manufactured hydraulic barrier consisting of clay (sodium bentonite) bonded to a layer or layers of geosynthetics
Typically 3.0 to 6.0 kg/m2 sodium bentonite clay
Very low permeability
Self-healing if punctured
Replaces compacted clay liners
Hydraulically equivalent to 0.6 meters of compacted clay in many applications
Weather
GCLs can be installed in extreme temperatures that would prevent compaction of a clay liner
May be limited due to weather constraints for overlying geomembrane welding
Why is bentonite a good
liner material ?
It swells when hydrated
Bentonite swells up to 15 times its original volume if unconfined.
Bentonite expands and conforms to irregular surfaces, penetrations, and infiltrates cracks and voids.
