Abstract (en)
[origin: DE4335290A1] The invention relates to a method of sealing soil bodies (1), in particular landfill sites, old deposits, pipelines or the like, or even foundation pits to be constructed, with the use of sealing substances. In this method, at least one borehole (2) is driven under the soil body (1) from the surface outside the soil body (1) by means of a fully path-controlled drilling method and in the process the sealing substance is injected into the surrounding soil area of the borehole (2). To carry out the method, nozzles for injecting the sealing substance into the ground are arranged on the controllable, remotely guided drilling head. <IMAGE>
