CCX™ is part of a revolutionary class of construction materials called Geosynthetic Cementitious Composite Mats and Barriers (GCCM/Bs). It is a flexible, concrete filled geosynthetic, that hardens on hydration to form a thin, durable, water proof concrete layer.
Essentially, it’s Concrete on a Roll™. CCX™ allows concrete installation without the need for plant or mixing equipment while also reducing vehicle movements and contractor burden. Simply unroll and just add water.
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 low permeability.
CCX™ can be hydrated either by spraying or by being fully immersed in water. CCX™ products exceed the minimum requirements of ASTM D8364 – Standard Specification for GCCM Materials.
Benefits of CCX™ as a Bulk Water Infrastructure Liner
Rapid Installation
The speed of installation and high early strength gain means that infrastructure down-time is minimised. In critical infrastructure, where maintenance shut-down periods are fixed, this allows for much greater areas to be lined or repaired.
Reduced Seepage
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 fibre reinforcement imbedded within the its structure. This prevents crack propagation whilst retaining low levels of permeability.
Composite Solution
Composite Solution CCX™ combines the low permeability 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.

Properties of CCX™
- High Impermeability: CCX™ has an LLDPE geomembrane backing ensuring the material has very low permeability, significantly reducing or eliminating seepage losses.
- Durable: CCX™ has a high degree of durability with abrasion resistance more than 3.5 times that of standard OPC concrete.
- Long-Term Performance: CCX™ has very good long-term performance with a life expectancy in excess of 50 years.
- Lower Carbon: CCX™ is a carbon efficient concrete solution that offers significant embodied carbon reduction compared to conventional concrete linings.
CCX™ GCCM/B Applications
Bulk Water Infrastructure Lining & Remediation
CCX™ can be rapidly unrolled to line earth canals as well as remediating existing concrete bulk water infrastructure. It is significantly faster, easier and more cost effective to install than conventional lining methods.
The LLDPE geomembrane backing to CCX™ ensures the material has very low permeability. The composite concrete top cover provides a high degree of long-term durability.
As a result, CCX™ is the ideal solution for the lining and remediation of channels and irrigation canals, increasing their operational life and reducing
water seepage losses.
