PROBLEM TO BE SOLVED: To provide an inexpensive ground consolidator liquid having a high expansion ratio and an excellent expansion stability. SOLUTION: A ground consolidator liquid comprises liquid A essentially comprising water glass, a polyol and water and liquid B essentially comprising a polyisocyanate. Here, the polyisocyanate has a dinuclear content of 55 wt.% against the total nuclear component and a 2,4-isomer content of 25 wt.% or larger against the total dinuclear component. Preferably, the polyisocyanate has a weight ratio of 2,4-isomer to 2,2-isomer within the dinuclear component of from 25/2 to 80/0.1. |
