ABSTRACT:
A method of sealing leaks is disclosed comprising the use of a bituminous rubber latex emulsion. The emulsion is introduced into the passage through which a fluid is leaking by injecting, often at considerable pressures and a coagulant is used to coagulate the emulsion. Water may be used as a coagulant. Alternatively, the emulsion may be carried into the passages by the water.
