In-situ injection test was carried out in fine sand layer with ordinary portland, colloid and ultra-fine cement. Permeability of the sand layer was 10{sup {minus}3} cm/sec. Suspension grout with ordinary portland and colloid cement was impossible to permeate into the sand. However with ultra fine cement small solidified sand was obtained and with ultra-fine cement-waterglass grout, water cement ratio of 0.8 and waterglass concentration of 75%, solidified sand with expected volume can be obtained.
