Coletanche, Our Company: Innovation and Excellence in Bituminous Geomembranes

Our Mission and Expertise

At Coletanche®, we specialize in the design, manufacture, and global distribution of high-performance bituminous geomembranes for civil engineering projects. Our geomembranes are engineered to provide long-term, reliable waterproofing solutions across a variety of sectors including hydraulic infrastructure, environmental protection, and transportation. With over 30 years of experience and more than 30 million square meters installed worldwide, Coletanche® is trusted by engineers and project managers globally.

A Global Presence

Coletanche® geomembranes are installed in more than 70 countries worldwide. We serve markets in Europe, Africa, the Middle East, Asia, North and South America, and Australia, ensuring that our waterproofing solutions meet the needs of diverse environments and regulatory standards.

Commitment to Quality and Sustainability

Our production facilities are constantly evolving to maintain the highest levels of quality. In 2001, we modernized our factory, increasing our production capacity to over 30 million m², and in 2006, we added a dedicated production line for our Coletanche® geomembranes. Today, we continue to improve our processes, reducing environmental impact and ensuring the highest quality standards in every product we deliver.

Key Features of Coletanche® Geomembranes

  • Superior Waterproofing: Coletanche® geomembranes offer unparalleled waterproofing performance, ensuring the long-term stability of civil engineering structures such as dams, canals, and landfills.
  • Global Certifications: Our products meet stringent international standards, including ISO and other environmental certifications, ensuring they are safe and reliable for large-scale projects.
  • Sustainable Practices: Coletanche® is committed to reducing its environmental impact through waste reduction and energy-efficient production processes.

In 2001, work began to modernise the production facilities at the Courchelettes site: the plant and industrial processes were completely refurbished and production capacity increased to more than 30 million m². As a result, the company completed further expansion work in 2006 and installed a new line to manufacture COLETANCHE geomembranes. These products are specifically designed for civil engineering projects and large-scale works thanks to the unique 5.10 ml wide design.
