As part of the construction of a new underground railway line in \u0141\u00f3d\u017a, our subsidiary Soletanche Polska carried out successfully its first compensation grouting project to ensure the safe passage of a TBM under historic residential areas.<\/strong><\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n Compensation grouting is not a very commonly used technology in Poland. Underground tunnels are designed to pass under existing streets, but rarely under buildings.<\/span><\/p>\n The construction of the new underground railway network in \u0141\u00f3d\u017a, which will connect the two stations \u0141\u00f3d\u017a Kaliska and \u0141\u00f3d\u017a Fabryczna, is particularly complex: it includes the completion of the cross city tunnel, built with a TBM under a residential area.<\/span><\/p>\n Soletanche Polska was mobilized to stabilize the ground and reduce settlement of the houses located directly above the tunnel under construction.\u00a0<\/strong>For the first time in its history, our BU used compensation grouting. This technology involves injecting a cement slurry into the ground to fill voids and cavities in the native soil.<\/span><\/p>\n<\/div>
