Modern mining operations demand high-performance solutions that ensure environmental safety, chemical resistance, and long-term durability. In this context, the COLETANCHE® bituminous geomembrane stands out as a strategic solution for projects where waterproofing is not optional, it is critical.
Manufactured by Axter, an internationally recognized company specializing in advanced waterproofing systems, COLETANCHE® combines modified bitumen technology with internal reinforcement to deliver superior performance under extreme conditions.
COLETANCHE® is a waterproofing system composed of:
Thanks to this composition, it offers:
Unlike many synthetic geomembranes, it combines flexibility and structural robustness, which is essential in mining environments where differential settlement and ground movement are common.
Mining operations handle large volumes of:
Without a reliable waterproofing system, risks include:
International organizations such as the United Nations Environment Programme promote responsible waste management and environmental protection practices. In this context, selecting the right waterproofing system becomes a strategic decision.
Tailings storage facilities contain mining waste with long-term contamination risks. COLETANCHE®:
Heap Leach Pads
Leaching processes require complete containment of aggressive chemical solutions.
Key advantages:
Thanks to its bituminous composition, it:
| Feature | COLETANCHE® | Traditional Synthetic |
| Puncture resistance | High | Medium |
| Adaptability | Excellent | Variable |
| UV resistance | Very high | High |
| Chemical stability | High | High |
| Service life | Extended | Extended |
Its reinforced structure reduces risks from sharp objects commonly found in mining environments.
It tolerates ground movement without cracking.
Modified bitumen provides a protective layer that enhances durability.
Thermal welding ensures reliable hydraulic continuity.
Mining faces increasingly strict environmental regulations. COLETANCHE® contributes to:
Its long service life also reduces replacement frequency, lowering the project’s overall environmental footprint.
Mining projects can operate for decades, making long-term reliability essential.
This geomembrane provides:
A single leak in a mining facility can result in millions in losses. Prevention is always more cost-effective than remediation.
Material quality must be matched by proper installation:
Due to its weight and stability, COLETANCHE® presents lower wind uplift risk during installation — a common challenge in open-pit mining environments.
While initial investment may be comparable to other alternatives, real savings come from:
In mining, investing in prevention protects both the environment and the project’s profitability.
Modern mining increasingly demands solutions that are:
The combination of polymer-modified bitumen and advanced engineering positions COLETANCHE® as a forward-looking solution ready to meet future environmental and operational challenges.
The COLETANCHE® bituminous geomembrane represents a reliable, durable, and technically advanced solution for the mining industry.
In a sector where environmental safety and operational efficiency are priorities, a robust waterproofing system makes the difference between a successful project and one exposed to significant risk.
Investing in high-quality waterproofing technology is not just a technical decision — it is a strategic investment in the sustainable future of mining.
Yes. It is designed to withstand chemical solutions used in leaching processes, ensuring long-term chemical stability and durability.
Absolutely. Its modified bituminous composition maintains flexibility in low temperatures and resists high temperatures and UV exposure.
It provides greater adaptability to differential settlement and improved puncture resistance, reducing structural failure risks in irregular terrain.
