Abstract: An injection or grouting body for the transfer of mechanical stresses in structures in above-ground or below-ground construction, and for insertion into a borehole, in slits or similar openings, has a centrally-arranged filling tube and at least one fabric stocking surrounding the filling tube. The filling tube is embodied as a fabric stocking and one or a plurality of reinforcing wires and/or rods, and/or pipes and/or ridged sheet metal strips are arranged on site so as to be adaptable, axis-parallel between the fabric stockings. An outer closed fabric stocking is arranged along the axis of the injection body about its inner filling tube (Fabric tube) that is open at its lower end. The reinforcing wires or rods are arranged on the outside of the inner fabric stocking and are attached to the fabric of the outer stocking in such a way that it can be ensured that, following filling or grouting, the reinforcement will remain in position.

Abstract: A method and apparatus for enabling a subsequent stabilization of buildings with precast floors including several longitudinally extending girders resting with respective ends thereof on opposite building walls. The ends of the longitudinally extending girders are clamped to each other and to the building end walls carrying the girders. Two outermost longitudinally extending girders of the floor zone to be stabilized are clamped together with respectively adjoining parallel building side walls by grouting anchors in such a manner that the floor zone to be stabilized is encompassed by a rugged ring anchor. The floor zone may also be reinforced by the provision of longitudinally extending and transversely extending anchors incorporated into the floor in a lattice-shaped fashion.

Abstract: A grouting anchor to be inserted in a pre-drilled hole (3) comprises a stopper (4) sealing the drill hole at its orifice, this stopper being provided with an inlet opening (6) for the grouting compound.In order to be able to monitor from the outside the formation of the plug of grouting compound, the stopper (4) is equipped with a backflow opening (7) for grouting compound, this opening terminating into a forward, air-permeable collecting cage (8) which latter, after curing of the grouting compound, can be separated from the stopper (4).
