Motivation
Soil is an important basis of existence and an only partially renewable resource.
More than half of the waste generated in Germany is mineral waste. The use of excavated soil has a great potential to conserve resources. Through their use in the economic cycle, large quantities of natural, mineral raw materials such as natural stones, sands, gravel, or building materials obtained from them can be substituted. Germany is undergoing the necessary transformation towards a resource-conserving and sustainablerecycling economy. In this way, natural raw materials and landfill space can be saved and the objectives of the German Waste Management and Product Recycling Act, the European Waste Framework Directive, or the German Resource Efficiency Programme (ProgRess) can be achieved.
Restoring soil-like conditions
All construction measures are associated with interventions in the soil and its structure. In most cases, a complete soil replacement is necessary to ensure the functionality of the erected structures. The use of the excavated material for the production of liquid soil enables us to reestablish soil-like conditions and thus to keep the impact of an intervention as low as possible. Physical properties, load - bearing capacity, and water conductivity are largely retained.
Controllability
Increasing complexity, cost pressure, and high quality expectations put enormous demands on the backfilling material in today's world. Therefore, the topic of controllability of liquid soil is very important for us. We develop a backfilling material whose final properties can be influenced.
