Claim 1
Independent Claim

A METHOD OF FORMING A STABILIZED STRUCTURE COMPOSED ESSENTIALLY OF NATURAL SOIL AND A STABILIZER THEREFOR, WHICH CONSISTS ESSENTIALLY OF ADMIXING WITH THE NATURAL SOIL A MONOMERIC WATER SOLUBLE ARCYLATE OF A POLYVALENT METAL, AND A REDUCTION-OXIDATION CATALYST, FORMING THE MIXTURE INTO THE DESIRED STRUCTURAL FORM, AND THEREAFTER POLYMERIZING THE MONOMERIC ACRYLATE IN THE PRESENCE OF SUFFICIENT MOISTURE TO AT LEAST PARTIALLY IONIZE SAID ARCYLATE AND SAID CATALYST, THE POLYMERIZATION BEING CARRIED OUT AT ATMOSPHERIC TEMPERATURE AND PRESSURE, TO PRODUCE A STABLE SOIL-POLYMER-WATER STRUCTURE IN SAID DESIRED FORM.
