Sprayed Concrete Has Many Advantages
- Application to any elevations because sprayed concrete adheres immediately and bears its own weight
- Can be applied on uneven substrates
- Good adhesion to the substrate
- Totally flexible configuration of the layer thickness on site
- Concreting without formwork
- Reinforced sprayed concrete is also possible (mesh/fiber reinforcement)
- Rapid load-bearing skin can be achieved without forms or long waiting times
Requirements for Sprayed Concrete
The multiple demands placed on sprayed concrete today no longer allow standard solutions. Dependent on the spray process and the type of structure, different conditions are imposed on the sprayed concrete during application and in service.In tunnel construction sprayed concrete is normally used for excavation stabilization, in open-pit mining and on major construction sites it is typically used for rock and soil stabilization on slopes. In bridge and other civil engineering repair and refurbishment works, sprayed concrete is often used specifically because formwork can thereby be dispensed with.
