LNG Canada – Exceptional foundations for a landmark cryogenic tank

To build the largest cryogenic LNG tank in North America, in a high-seismicity zone, Entrepose Contracting and VINCI Construction Grands Projets had to design a truly unprecedented foundation system.

Our challenge? To ensure the long-term stability of a 225,000 m³ capacity structure, weighing several thousand tons, while safeguarding its integrity throughout its entire operational life cycle.

Our solution? A dense grid of close-ended driven steel pile inclusions, not connected to the tank slab.

🔍 These piles act as rigid inclusions, providing:
✅ Enhanced bearing capacity
✅ Liquefaction resistance
✅ Control over differential settlements — the most critical factor in preserving the structural integrity of such a tank over time

📈 Field data confirmed the efficiency of this foundation system, designed specifically for this project’s geotechnical context.

🔗 This achievement demonstrates our ability to rethink conventional engineering approaches and deliver robust, adaptive, and efficient solutions for today’s most demanding energy infrastructure, while still maintaining a cost-effective approach.
