Canal Lining | Canal de Provence, Saint-Julien, France
15,000m² of CCX-M® Installed for Canal Rehabilitation
Project Overview
In April 2023, 15,000m2 of Concrete Canvas Ltds CCX-MAT® (CCX-M®) GCCM was used to line and provide erosion control to a canal, as part of the old Canal du Verdon in Saint-Julien, France.
Designed as part of a vast network, the Canal de Provence supplies water to more than two million people in 110 towns and villages, 6,000 farms with a total of 45,000 irrigated hectares, and 500 factories large and small. To maintain a continuous supply of water to the Canal de Provence infrastructure, the rehabilitation of part of the Canal du Verdon – which was abandoned after the construction of the Canal de Provence canal – was needed as part of works on the Maurras gallery.
Solution
The section of Canal du Verdon was initially designed out of soil substrate; however, inactive use had caused the structure to deteriorate due to erosion from rain-fall and damage from vegetation growth. As the canal went through the Regional Parc du Verdon, client chose CCX-M® for the project due to the materials low impact – needing very little machinery to install – being easier and faster to install in comparison to other standard solutions.
Design & Installation
- Vegetation growth within the canal was removed and 500mm of clay was compacted to form the channel and reduce permeability
- Bulk Rolls of CCX-M® specified
- Transverse layup
- Perimeter edges secured in anchor trenches
- Screwed and sealed overlap joints
- Hydrated using a water bowser and hose following guidance for drying conditions in warm weather
Summary
A total of 15,000m² of CCX-M® was installed by a team of 6 installing between 300/400m² of CCX-M® during a typical 8-hour shift. Even though there were delays with the installation – with the area experiencing adverse weather conditions and flooding – client was extremely pleased with how quickly and easily CCX-M® could be installed and were very appreciative of Concrete Canvas Ltd support during onsite visits.
