CC KEY PROPERTIES
CCH has excellent impermeability. It has been independently tested to BS-EN-1377 to have a hydraulic conductivity better than 1×10-12 m/s.
CCH has a hard armour surface, protecting the geomembrane liner from in-service puncture, abrasion, weathering, burrowing animals and UV degradation.
CCH has been shown to have excellent resistance to a wide range of chemical reagents, including hydrocarbons, digestates and acidic leachates.
CCH incorporates a high-visibility welding strip, allowing the joint to be thermally bonded with an air channel for fast and simple on-site pressure testing of 100% of the welding joint without additional offsite destructive testing.
