CCX™ has been developed specifically for canal lining and can be rapidly unrolled to line and remediate bulk water infrastructure. CCX™ has excellent impermeability significantly reducing water seepage losses in applications such as canals, waterways and hydroelectric channels.
WHAT IS CCX™?
CCX™ consists of two interconnected layers of geotextile that encapsulate a specially formulated dry concrete mix. An LLDPE geomembrane backing ensures the material has very high impermeability. The composite concrete top cover provides a high degree of long-term durability.
CCX™ can be rapidly unrolled to line and remediate canal infrastructure. It is significantly faster, easier and more cost-effective to install than conventional lining methods. CCX™ can be hydrated either by spraying or by being fully immersed in water.
As a result, CCX™ is the ideal solution for the lining and remediation of large channels such as irrigation canals, increasing their operational life and reducing water seepage losses.
Two variants of CCX™ are currently available: CCX-MAT™ (CCX-M™) for erosion control applications & CCX-BARRIER™ (CCX-B™) for containment critical applications. CCX™ products exceed the minimum requirements of ASTM D8364 – Standard Specification for GCCM Materials.
Learn More About CCX-M
CCX-MAT (CCX-M™) has a 0.3mm LLDPE backing to ensure the material has excellent impermeability. Jointing of CCX-M™ is typically through a combination of screws, adhesive sealant and thermal bonding. It is not possible to create a testable thermally welded joint with CCX-M™. For applications where this is required, CCX-B™ should be used.

CCX-BARRIER (CCX-B™) has a >1.0mm LLDPE geomembrane backing for containment critical applications. CCX-B™ joints can be thermally welded and air-channel tested to provide quality assured impermeable joints. Standard thermal welding equipment and joint testing equipment for LLDPE geomembranes can be used.
Bulk Water Infrastrucutre
CCX can be used to line large hydraulic structures such as irrigation canals, navigable canals,
and waterways. The properties of CCX make it well suited for lining large profiles, either as
remediation for existing concrete canals or new linings for earth canals.
CCX can be used to line and upgrade existing reservoirs with the benefit of providing a protected
geomembrane above the waterline where existing liners may be susceptible to damage.
CCX can be used either to line the exposed reservoir crest area or the entirety of the containment surface.
CCX can be used to line large uniform profile channels such as feeder canals and flumes
for hydroelectric systems. Please contact Concrete Canvas for high flow rate projects to ensure
suitable fixings and jointing methods are specified.
PROPERTIES OF CCX™
CCX™ has an LLDPE geomembrane backing ensuring the material has very high impermeability, significantly reducing or eliminating seepage losses.
CCX™ has a high degree of durability with abrasion resistance more than 3.5 times that of standard OPC concrete.
CCX™ has very good long-term performance with a life expectancy in excess of 50 years.
CCX™ is a carbon efficient concrete solution that offers significant embodied carbon reduction compared to conventional concrete linings.
The speed of installation and high early strength gain means that infrastructure downtime is minimized. In critical infrastructure, where maintenance shut-down periods are fixed, this allows for much greater areas to be lined or repaired.
Over time conventional concrete liners can suffer from widespread cracking due to differential ground movement, leading to significant seepage losses, undermining and, in the worst instances, complete channel collapse.
CCX™ can accommodate a high level of differential ground movement due to the fiber reinforcement embedded within its structure. This prevents crack propagation whilst retaining high levels of impermeability.
CCX™ combines the impermeability of a geomembrane with the protection and durability of concrete. CCX™ can be installed as rapidly as conventional geosynthetics and 24 hours from hydration will cure to create a hard-wearing concrete liner which is ready to use.
LOW LOGISTICAL FOOTPRINT
CCX™ has an un-hydrated unit weight of 14.5-15.5kg/m² compared to ~220kg/m² for 10cm of cured concrete. This means it is typically more than 10x more efficient in terms of the logistical footprint, requiring fewer trucks and reducing operational overheads.
CCX™ is available in two standard roll sizes: bulk rolls or smaller, lighter batched rolls. The quantity per roll differs between the CCX™ types as shown in the table below.
|CCX™ Type||Thickness (mm)||Roll Width (m)||Mass per Unit Area (kg/m²)||Bulk Roll Coverage (m²)||Bulk Roll Length (m)|
