Abstract

The invention pertains to a process for sealing off ground sites in particular a waste dump, abandoned dumping grounds, pipelines or the like, or also excavated construction sites, using sealants, wherein a fully course-controlled boring technique is used to drive at least one bore underneath the ground site from the surface outside the ground site and the sealant is injected into the soil surrounding the bore. To implement the process, jets for injecting the sealant into the soil are mounted on the steerable remote-controlled boring head.
