Abstract

The invention relates to a method for sealing water-bearing capillaries in rock, a liquid composition which is utilised in the method, and the use of a such liquid composition. The method comprises to drill holes in an adapted hole pattern in the rock, to inject a liquid composition with a silica carrier in aqueous solution into the holes at a high pressure, so that the liquid composition thereby forces away water in the water-bearing capillaries within a sealing area enclosing the hole pattern. According to the invention, the liquid composition further comprises a calcium carrier in aqueous solution, wherein the silica carrier and the calcium carrier together with at least water, at a controlled gel-formation rate, form an irreversible calcium silica hydrate gel in the sealing area after injection, so that water transport through the water-bearing capillaries within the sealing area is prevented. The invention has its main application when tunnelling through highly water-bearing, porous rock layers, but can also be used for other similar applications, for instance when mining or constructing water power plants.
