Method of forming a subterranean asphaltic water barrier

Claim 1

THE METHOD OF FORMING A SUBTERRANEAN ASPHALTIC WATER BARRIER IN SITU IN A PRESELECTED SUBSURFACE STRATUM OF SOIL AND IN A PLANE SUBSTANTIALLY PARALLEL TO AND COEXTENSIVE WITH THE SOIL SURFACE, WHICH COMPRISES THE STEPS OF: (A) FORMING A TRANSLATING CAVITY IN A PRESELECTED SUBSURFACE STRATUM OF SOIL IN A PLANE SUBSTANTIALLY PARALLEL WITH THE SOIL SURFACE WITHOUT SIGNIFICANTLY PARALING THE STRUCTURE OF THE SOIL SURFACE, SAID CAVITY HAVING THE BOTTOM SURFACE THEREOF IN A PLANE SUBSTANTIALLY PARALLEL WITH THE SOIL SURFACE, (B) SPRAYING ONTO SAID BOTTOM SURFAFE AN AQUEOUS ASPHALTIC EMULSION WHICH QUICKLY BREAKS AND SETS TO FORM A CONTINUOUS WATER IMPERMEABLE FLEXIBLE ASPHALT MEMBRANE ON THE BOTTOM SURFACE OF SAID CAVITY PROIR TO CLOSING OF SAID CAVITY; AND (C) THEREAFTER CLOSING SAID CAVITY TO THEREBY FORM IN SAID SUBSURFACE STRATUM OF SOIL AN ASPHALTIC WATER BARRIER IN A PLANE SUBSTANTIALLY PARALLEL TO AND COEXTENSIVE WITH SOIL SURFACE.

Claim 2

THE METHOD OF FORMING A SUBTERRANEAN ASPHALTIC WATER BARRIER IN SITU IN A PRESELECTED SUBSURFACE STRATUM OF SOIL AND IN A PLANE SUBSTANTIALLY PARALLEL TO AND COEXTENSIVE WITH THE SOIL SURFACE, WHICH COMPRISES THE STEPS OF: (A) FORMING A TRANSLATING CAVITY IN A PRESELECTED SUBSURFACE STRATUM OF SOIL IN A PLANE SUBSTANTIALLY PARALLEL WITH THE SOIL SURFACE WITHOUT SIGNIFICANTLY PARALING THE STRUCTURE OF THE SOIL SURFACE, SAID CAVITY HAVING THE BOTTOM SURFACE THEREOF IN A PLANE SUBSTANTIALLY PARALLEL WITH THE SOIL SURFACE, (B) SPRAYING ONTO SAID BOTTOM SURFAFE AN AQUEOUS ASPHALTIC EMULSION WHICH QUICKLY BREAKS AND SETS TO FORM A CONTINUOUS WATER IMPERMEABLE FLEXIBLE ASPHALT MEMBRANE ON THE BOTTOM SURFACE OF SAID CAVITY PROIR TO CLOSING OF SAID CAVITY; AND (C) THEREAFTER CLOSING SAID CAVITY TO THEREBY FORM IN SAID SUBSURFACE STRATUM OF SOIL AN ASPHALTIC WATER BARRIER IN A PLANE SUBSTANTIALLY PARALLEL TO AND COEXTENSIVE WITH SOIL SURFACE.
