Injection In Underground Construction And Tunnel
Underground structures as tunnels, hydroelectric power plants, storage caverns etc are always expensive to build and have a major value to the society, then as infrastructures they are directly responsible for wealth creation and development, justifying thus also their need of better and constant maintenance.
Grouting works are a significant part of these important projects, mainly in:
Consolidation and strengthening of weak soil during tunnelling excavation
Curtain grouting for concrete and earth dams
Ground settlement control
Waterproofing of existing structures
Preventing spreading of hazardous contaminants
Foundation plate formation
Re-opening of old dams and tunnels
As seen, injection techniques help to solve problems that show up in the construction or during the operative life for the maintenance of such important structures.Today the range of products and techniques available for injection is quite wide.
