Process for the preparation of containment barriers impermeable to fluids, which comprises: a) hydraulic fracturing of the ground to create extensive fissures, the above fracturing being effected by injecting, under pressure and through wells, compositions selected from: i) aqueous solutions or dispersions of materials capable of gelling; ii) aqueous dispersions of solids; iii) materials, or relative solutions/dispersions, capable of solidifying on cooling; b) subsequent maintenance under pressure until the formation of the above containment barriers, essentially consisting of compositions (i)-(iii). |
