​GROUTING

Expertise, many years of experience and state-of-the-art specialised equipment makes us competent in the following areas of grouting technology:​

ROCK GROUTING

• Curtain and contact grouting in the construction of dams

• Grout sealing to prevent water inflow in tunnel and shaft construction
  

• Stabilisation and sealing of fault zones in the rock mass

GROUTING LOOSE ROCK

• Soft gel base for horizontal sealing of excavations in groundwater
• Stabilisation grouting to increase the load bearing capacity of the subsoil
• Compaction grouting to increase the load bearing capacity of the subsoil

SPECIAL APPLICATIONS

• Contact grouting of the space between the concrete inner shell of pressurised water tunnels and rock
• Passive prestressing of concrete inner shells in the pressurised water tunnels of hydroelectric power stations
  
• Investigation of water permeability in rock (Lugeon test)
  
• Chemical grouting​
  

RESIN- OR CEMENT INJECTION AGAINST MOISTURE AND PRESSURE WATER

• Field injection, compartment injection in connection with waterproof lining
  

• Crack injection according to German technical rule ZTV-Riss
  
• Grout curtains
  
• Cement injection
  
• Contact grouting
  
• ​All kind of injection by use of Acrylic Gel or PU-resins for wa­ter­proo­fing of underground structures (s.a. tunnels, caverns shafts etc) also in connection with membrane sealing systems.
