what is CC Hydro?

CC Hydro (CCH) is a revolutionary new containment product from Concrete Canvas Ltd. It combines the company's concrete impregnated fabric technology with a highly impermeable, chemically resistant geomembrane liner. The liner incorporates a hi-visibility welding strip which allows joints to be thermally bonded with a double-track or triple-track air channel for on-site testing.

Reduced Life-Cycle Costs

CC Hydro combines the impermeability of a containment liner with the hard armour protection and durability of concrete, reducing install times and simplifying logistics.

CC Hydro does not require a protective top cover. This removes the need for additional excavation, treatment of contaminated arisings and import of costly fill material.

CC Hydro can be laid directly onto existing profiles without loss of volume capacity for refurbishment projects, providing significant overall time and cost savings.

CC Hydro provides effective weed suppression, eliminating the ongoing maintenance cost of soil covered systems. It reduces the end-of-life costs associated with treatment of any contaminated top cover.



High Impermeability

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 puncture, abrasion, weathering, burrowing animals and UV degradation.

Chemical Resistance

CCH has been shown to have excellent resistance to a wide range of chemical reagents, including hydrocarbons, digestates and acidic leachates.

Testable Joints

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.
