Abstract The article presents 3 new methods of soil simultaneous strengthening and detoxicating. The methods are based on using hydrate complexes obtained by means of silica sol, foam concrete and phosphates. 3 technologies are suggested after silica sol, foam concrete and phosphates. The new technologies are named soling, aerating and phosphating. The level of soil strengthening is from 0,2 MPa for aerating and soling and more than 3 MPa for phosphating. The point of detoxication is to obtain heavy metal ion silicates and phosphates with very low solubility product. The level of detoxication is more than 1000 TC (tolerable concentration, mg/g).
