Abstract: The aim of the invention is to provide an improved method for securing, stabilizing and recovering areas of land and subsoil above and below water. To this end, interlinked (used) motor vehicle tires (7) are used to secure the land. The necessary weighting is provided by concrete (19) injected into a protective casing (30).

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).

Abstract: An injection anchor designated for masonry or the like consists of a tube (1) closed at its rear end and of an elastically expandable jacket (2) that surrounds the tube.In order produce an injection anchor as a reasonably priced mass production article, the tube (1) is provided with a number of diametrically opposing, rounded-off indentations (9, 10) and the elastic jacket (2) is designed as a hose, which extends over the entire length of the tube (1), the ends of the hose being tucked into the tube ends and clamped solidly to the tube (1) by means of rivet-like fasteners (5, 6).

Abstract: Bracket-style support elements (10) to be mounted subsequently to a building wall (14, 15) for a curtain facade (13) consist of a horizontal support (2) with at least two associated, bolt-like wall mounting elements. In order to make it possible also to use normal facing stones, to be able to anchor the support element securely in the foundation masonry (14, 15), and to ensure reliable protection against wetness as well as good insulation, the wall mounting elements are constituted by grouting anchors (4) surrounded up to the support (2) by a sleeve (7) and exhibiting respectively a central anchoring bolt (5) with a barbed disk (6) arranged at the insert end (22), and the support (2) is constituted by an L-shaped rail (3), the grouting anchors (4) projecting from the vertical leg (8) of this rail on the side facing away from the horizontal leg (9).
