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.
