<p>A process is described for sealing leaks in water-bearing pipes and vessels, by which it is possible to seal leaks without the danger of disturbing the flow of the aqueous medium through the pipe. This is achieved according to the invention if an aqueous sealing liquid, containing cellulose if desired, based on liquid water glass is used which contains an amount of water glass (sodium silicate) solution which gives a comparatively high pH >/= 10.5 to </= 11.5 in dilute solution at the boiling point of water and this is processed at elevated temperature in the range 30 - 90 DEG C.</p> |
