Abstract: In practical applications, sodium-silicate grout injections are being used increasingly for underpinnings, improvement of bearing capacity of foundations, or as a supporting measure for tunneling projects. In many instances significant creep behavior of the solidified materials under sustained loading have been observed. This time dependent performance results from a superposition of the elastoplastic properties of the sand to be grouted and the mainly viscous shear resistance of the injected silicate-gel.
