ABSTRACT:
In situations where pressurized unsaturated brine or other unwanted liquid seeps through incompetent or soluble rocks, a pair of dams are constructed within a passageway, and the interface between the dams and the host rock is sealed. Thereafter, a hydrophobic liquid is injected under pressure within the passageway between the two dams thus impregnating the microfracture system within the host rock. A monitoring installation is used to sample the area on the flood side of the first barrier. This flood isolation method is also useful in containing other wastes such as in nuclear repositories.
