To meet landscape integration requirements and to overcome scarcity in available logistics space the Swiss startup Eccus has developed a standardized solution with the underground design of a cavern system to utilize previously unused space. Access is via elevator shafts with a load capacity of up to 12 tons. The so called ECO-Cavernes® have a diameter of up to 24 meters and are located more than 20 meters below ground level. They can be installed beneath existing buildings. The building process is fast and cheap because of high standardization. Feasibility checks of geology and accessibility are part of the process.

The caverns are not counted towards land sealing or building limits. The natural thermal insulation of the earth allows for a reduction in heating and cooling energy. Oxygen can be reduced to as little as 13.5 %, thus providing significant fire protection benefits. Automated processes can be implemented underground without any problems, human-operated processes can also be implemented within certain limits. They also offer significant energy savings – up to 50 % for storage in a controlled atmosphere.
The product ECO-Caverne® is available in three dimensions:
- 12 meters in diameter, volumes between 8,000 m³ and 14,000 m³
- 18 meters in diameter, volumes between 9,500 m³ and 26,000 m³
- 24 meters in diameter, volumes between 23,000 m³ and 39,000 m³
The target markets and customers include data centers, energy distributors, large-scale distribution systems, automated high-bay warehouses, mid-season fruit storage, archives, and the storage or production of pharmaceutical or electronic components.
„Our solution enables us to handle an underground throughput of approximately 140 pallets per hour with an automated system (storage and retrieval machine), as our fire protection concept eliminates the need for constant staff presence,“ says Eccus-CEO Andrew Bourget.
„We have also observed an increased demand for storage space that ensures the security of supply for both industrial goods and food and basic needs of the population in the event of a crisis or conflict,“ adds Bourget.
The product fits into the current context of regulations in Switzerland and Europe regarding spatial planning and carbon emission reduction. Indeed, these laws are leading to new restrictions on industrial activity and land scarcity. Andrew Bourget: „However, thanks to the increasing automation of industrial processes, we can now consider using underground spaces to expand existing sites while simultaneously reducing energy costs thanks to natural insulation. Moving automated processes underground therefore enables both densification of the industrial structure and greater preservation of natural spaces. The ECO-Caverne® also meets sustainability goals, as its lifespan extends well beyond a century.“
