ABSTRACT:
A method for preventing corrosion of an expandable mounting element which involves introducing a sealing composition into a mounting hole of a support structure first to fill the hole about half-way, then driving an expandable mounting element into the half-filled hole to displace the sealing composition initially against the base of the mounting hole and then up along the surface of the expandable mounting element until the excess emerges out of the mounting hole. A compressible impact device, which has an upper and lower part and a spring part fixed therebetween, is arranged so that an impact tool can be driven against the upper part to fully drive the expandable mounting element into the mounting hole, effecting a sealing compaction in correspondance with the pressure exerted by the spring part. All gaps and cracks are thereby sealed against corrosive media.
