摘要：Walls consisting of masonry, concrete or the like are sealed against rising damp and/or groundwater by driving injection bolts, which are through-bored in each case at least over a part of their length and are provided with radial passages, into the wall at a depth of 2/3 to 3/4 of the wall thickness, at predetermined intervals. During working, fluid sealing material, which can harden or set, is pressed through the injection-bolt through-bore, which opens out on the outer surface of the wall into which said injection bolts are driven. The sealing material penetrates into the capillaries of the adjacent wall region and solidifies there, as a result of which the wall region in question is sealed with respect to damp. The injection bolts have an elongate shank which is closed at its front end, in the direction in which said bolts are driven into the wall, and is also through-bored over its entire length. The wall of the said shank is provided with a number of passage openings which are offset with respect to one another in the longitudinal direction and continue into the through-bore. At the rear end of the shank, an enlarged head part is provided in which the through-bore opens into a connection for the mouthpiece of a pressing-in device.
