MeduSoil is a construction-tech spin-off of EPFL and develops a smart construction material which mineralizes carbon underground to produce strong, mineral binders which enable contractors build on solid foundations. The goal of the Innobooster project is to support MeduSoil in delivering real-life infrastructure repair works in collaboration with key industrial stakeholders and in performing all portions of the building process related to ground stabilization. Implementing ground stabilization works mitigates failures caused by environmental threats such as earthquakes, soil erosion and landslides. Ground stabilization represents a crucial challenge in all construction projects and a major market opportunity, worth CHF 28 Bn annually. It finds industrial applications in roads, railroads, airfields, embankments, reservoirs, canals and coastal engineering. Rapid urbanization, particularly in the developing regions, is fueling the ground stabilization market growth due to the scarcity of suitable land for development. At the same time, the need to perform such works is becoming even more urgent given recurring, extreme weather phenomena which cause extensive floods and soil erosion. In addition to this, rising sea levels threaten coastal zones and existing infrastructure, requiring ground erosion barriers. The role of ground stabilization is therefore critical when it comes to emergency response following natural hazards.
Was ist das Besondere an diesem Projekt?
The industry of ground stabilization hasn’t been disrupted in decades and current solutions are complex, expensive, mainly due to heavy equipment required for application, and often hazardous to the environment because of the extensive use of industrial fluids. MeduSoil develops a new ground stabilization agent for use in subterranean works. The reagent combines a carbon source, typically in the form of soil fertilizers extensively used in agriculture, with calcium and soil microorganisms. Once on site, MeduSoil’s reagent is mixed with water to create a large volume of reactive solution that is ready for application within 24 hours. The solution is pumped into the ground under low pressure, spreads over a large area and sets within 4-8 days. The result of MeduSoil’s applications is a strong, rock-like material produced out of typical soil to serve as solid foundation and protect infrastructure against failures and environmental hazards.
MeduSoil is currently involved in three full-scale pilots, among which a project with one of Switzerland’s largest construction and engineering consulting companies. MeduSoil has forged collaborations with partner companies as well as with local public authorities and Swiss suppliers of biotech solutions. This established traction serves as the best evidence that critical stakeholders from the industry recognized that MeduSoil is building something truly vauable and has a place in the market and the potential to grow into the next big thing in ground stabilization and environmental construction operations.
