By using a packer which is pushed as far over an anchor as the intended length of the moulding, the cavity in a borehole in the region of the bond can be completely filled with a reactive resin. Overhead work is possible even with slowly reacting resins. By using a catalyst on the packer, the reactive resin injected into the borehole behind the packer can be made to harden very rapidly.

Anchoring of tension members

The outer skin of armored earthwork constructions is attached to bands and the traction is transmitted to the ground by friction. The bands are made of a corrosion resistant, high strength weave or netting of reinforced organic, glass or carbon fibres or fibre mixtures and are preferably impregnated with liquid reaction resins such as epoxide, polyurethane or isocyanate resins. It is advantageous to impregnate the bands and then to harden them only after they have been laid.
