Compensation grouting<\/h2><\/div>

This technique is an essential complementary specialist measure in tunnel construction.<\/strong><\/h3><\/div>

Soletanche uses compensation grouting to reduce surface settlement during tunneling works. Compensation grouting prevents soil decompression caused by excavation works. This is achieved by injecting precise and calibrated quantities of grout between the tunnel and the structures that need to be protected.<\/p>\n<\/div>

Applications of compensation grouting<\/h2><\/h3><\/div>
    \n
  • Wherever there is a risk that tunnel construction may cause deformation of sensitive structures.<\/li>\n
  • All tunneling methods: using TBM machines, traditional methods (e.g. NATM), etc.<\/li>\n
  • Remedial programs \u2013 provides protection to existing structures in the event of unforeseen incidents during TBM progress.<\/li>\n<\/ul>\n<\/div>
