A method of stabilizing soil and aggregate for structural purposes including the step of mixing with water: (a) a soil aggregate base material; (b) a stabilization composition comprising: (i) an alkali metal silicate or other suitable gel precursor, and (ii) optionally a cation; and (c) a minimum amount of 1% of cement based on the weight of the resulting mixture, whereby sufficient water is added to the resulting mixture to hydrate the cement and thereby provide a stabilized soil aggregate matrix suitable for use in a structure. There is also provided a method of forming a structure which includes the steps of: (i) sampling a soil aggregate base material to carry out one or more Atterberg tests as well as UCS or CBR; (ii) determining target amounts of cement from the results of such tests; and (iii) substituting a percentage of the target amounts of cement with a stabilization composition comprising: (a) an alkali metal silicate or other suitable gel precursor; and (b) a cation, as well as a stabilization composition for use in the methods described above.
