Culvert Lining
Line culverts efficiently to restore flow and prevent leaks
Concrete Canvas® (CC) products offer a fast, flexible and efficient installation for Culvert Lining when compared with traditional methods such as bitumen coatings, sprayed concrete or precast sections. With CC products contractors benefit from significant technical and financial advantages, particularly where site access is restricted.
Traditional solutions such as sprayed bitumen and concrete are becoming increasingly prohibited by environmental agencies due to their adverse effects of local ecologies. CC’s low alkaline reserve, washout rate and embodied carbon mean it can be safely installed in live water courses without adverse effects.

Concrete Canvas® is the first Geosynthetic Cementitious Composite Mat (GCCM), established for more than 20 years
CC8® was installed in Newburn Culvert, Newcastle, UK, providing scour protection to a Victorian brick-built structure
User Benefits
Rapid Installation
CC can be laid at up to 200m²/hour, 10 times faster than traditional concrete.
Easy To Use
Requires less plant, fewer personnel and no on-site mixing or measuring — Just Add Water™.
Lower Project Costs
Faster installation and reduced logistics can make CC more cost-effective than conventional methods.
Lower Carbon
Uses up to 95% less material than concrete, cutting carbon and reducing transport needs.
Sectors Who Use Us
CC products are well established in their use to repair, re-surface and remediate ageing culverts. The unique composite construction of CC products enables a much thinner surfacing layer to be applied when compared to conventional concrete, significantly reducing volume loss on critical infrastructure. CC products unique properties also provide a lower carbon alternative to traditional concrete.
FAQs
Concrete Canvas® (CC) is the original Geosynthetic Cementitious Composite Mat (GCCM) and the first product to declare conformance to ASTM D8364 ‘Standard Specification for GCCMs’. It is a flexible, concrete filled geotextile that hardens on hydration to form a thin, durable and waterproof concrete layer.
Divert water (if lining an existing culvert). Remove vegetation, soil, gravel and any debris from pervious linings (such as loose bitumen coatings) to expose the corrugations in the culvert.
Damage to the culvert (e.g. voids or pitting created by rust or corrosion) must be filled with concrete, grout or compacted gravel depending on the designer requirements.
