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.
CCX® is primarily used for lining uniformly profiled erosion control applications. CCX® consists of two interconnected layers of geotextile that encapsulate a specially formulated dry concrete mix. CCX-MAT® (CCX-M®) is a variant of CCX® with an LLDPE geomembrane backing which ensures the material has very low permeability.
CCX-M® 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-M® 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.
CCX-UTILITY® (CCX-U®) is a variant of CCX® without an LLDPE backing. Whilst unsuitable for hydraulic applications such as channels, it may be used to line uniformly profiled slopes.
CCX® products exceed the minimum Type II GCCM requirements of ASTM D8364 – Standard Specification for GCCM Materials.

CCX-UTILITY® (CCX-U®) is manufactured without an LLDPE geomembrane backing. Whilst unsuitable for hydraulic applications such as channels, it may be used to line uniformly profiled slopes. CCX-U® may be used as an alternative to CCX-M® where erosion protection is required to counteract wind or rain acting directly on the slope only. CCX-U® can be jointed through a combination of screws, adhesive sealant and thermal bonding.

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, Concrete Canvas are developing CCX-BARRIER (CCX-B) – details to be released soon!
APPLICATIONS
IRRIGATION CANAL LININGCCX-M® can be rapidly unrolled to line uniformly profiled irrigation canals. Joints can be thermally bonded
or sealed with an adhesive then fixed with screws, to provide a low permeability lining solution.
CCX-M® can be rapidly unrolled to line a uniformly profiled channel. It is significantly faster, easier and
less expensive to install than conventional concrete lined channels.
CCX-M® can be rapidly unrolled to line uniformly profiled slopes. CCX-U® may be used as an alternative
to CCX-M® where erosion protection is required to counteract wind or rain acting directly on the slope only.
CCX-M® can be used either to line the exposed reservoir crest area or the entirety of the containment surface.
CCX-M® 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 minimised. 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-M® can accommodate a high level of differential ground movement due to the fibre reinforcement embedded within its structure. This prevents crack propagation whilst retaining low levels of permeability.
CCX-M® combines the low permeability of a geomembrane with the protection and durability of concrete. It 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.
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.
