Frequently Asked Questions

CCX^® membrane protection is used to provide a durable concrete armour layer over geomembranes such as HDPE. It protects liners from mechanical damage, UV exposure, weathering, animals and maintenance activities while preserving the integrity of the containment system.

CCX-U^® is suitable for protecting HDPE, LLDPE, PVC, EPDM rubber and Geosynthetic Clay Liners (GCLs). When used with GCLs, engineers should confirm that the confining stress provided during hydration meets manufacturer requirements.

CCX^® replaces thick poured concrete layers with a thin, high-performance concrete mat typically 5–12mm thick. This reduces installation time, cost, carbon footprint and logistical complexity, while minimising the risk of damage to the underlying membrane.

Yes. CCX^® is specifically designed for installation on steep slopes without the need for shuttering, geocells or formwork. It can be laid vertically, making it ideal for lined ponds, channels and containment structures.

CCX^® overlaps are thermally bonded using hot-wedge welding equipment to create a continuous, monolithic protective layer. This ensures structural continuity and long-term durability across the membrane surface.

Yes. Because CCX^® forms a thin concrete layer, it maintains the original storage and flow capacity of ponds, lagoons and channels far better than soil, gravel or rip-rap protection systems.

CCX^® installs significantly faster than traditional concrete solutions. Large membrane protection projects can be completed in days using small teams and minimal plant, reducing programme time and site disruption.

CCX^® provides long-term protection against UV degradation, weathering, animal damage and abrasion during maintenance activities such as de-silting, helping extend the service life of geomembrane liners.

No. CCX^® can be installed by general civil engineering contractors using standard site equipment, reducing reliance on specialist trades and lowering overall project risk and cost.

Yes. CCX^® has been successfully used on infrastructure and public works projects across Europe, including highway attenuation ponds and treatment ponds, delivering reliable performance and measurable cost savings.
