In the research project WiFaPu (Wrapping process for highly fiber-reinforced concrete using the example of a pump sump), a wrapping process is developed, combining the advantages of glass-fiber-reinforced and textile-reinforced concrete. The process involves spraying fine-grained concrete with short fibers onto a carrier sheet and textile reinforcement, producing a thin layer wrapped continuously to form components of varying thickness. Challenges in process development and material coordination are addressed to ensure durable components with simple geometries and a reduced CO2 footprint. Demonstrator pump sumps exhibit high load-bearing capacity and suitability for use, validated through load and filling tests.
