The enormous advantages of sprayed concrete as a construction process
and the improvement of equipment, materials and application know-how have made it an important tool for various types of work.
Sprayed concrete takes care of stability problems in tunnels and other underground constructions. Today sprayed concrete is a key factor for rock support in
< Tunnelling
< Mining operations
< Hydropower projects
< Slope stabilization
More than 90 % of all sprayed concrete is used for rock support.
In comparison with traditional concrete, sprayed concrete is used today to a relatively small extent, but when it is used, it is done so in many different
ways. Some examples:
< Pit curbing
< Canal lining
< Reconstruction and repair
< Sea walls
< Refractory
< Fire and corrosion protection
< Spraying of new constructions
< Agriculture (manure pits)
< Plastering and stabilizing of brick walls
Sprayed concrete is the building method of the future due to
< Flexibility
< Rapidity
< Economy
