Background

In October 2022, Concrete Canvas^® CCX-MAT^® (CCX-M^®) GCCM* was used to line a drainage canal off the new E65 highway in Lamia, Greece.

The drainage canal was designed to divert water run-off away from the new highway and into a live watercourse located a few kilometers away. However, cracks and vegetation growth within the unlined canal structure, combined with flowing water was causing the canal to erode, allowing for water to seep into the surrounding area – making the canal structure susceptable to failure and nearby fields susceptable to water logging and localised flooding.

Solution

The Greek Government and contractors wanted to examine a new solution that could provide protection from further cracks, vegetation growth and waterloss whilst accommodating the steep sides within the canal.

Poured concrete was considered to mitigate the issues, however, the steep sides of the canal would have made it difficult to install.

CCX-M^® was chosen due to its ability to be both quicker and easier to install. The materials flexibility allows for the canals steep sides to be accomodated whilst providing protection.

Conclusion

A total of 5,000m² was installed in 9 days – with an average of 150m² per hour installation rate – by a team of 6 installers. Both the Greek Government and the client were very happy with the final results and have already suggested Concrete Canvas – including CCX^® – for many other projects
