The steady anchorage of the system with the subsoil took place by means of special T-steel
nails.
For the installation of the T-Steel nails, holes had to be pre-drilled on account of the given
underground conditions (rock). For this a hand-operated drill was used. Then the nails were
rammed by use of a pneumatic hammer into the borehole filled with cement mortar.
There, where the slope was stabilised with shotcrete combined with GEWI anchors (fig. 3) the
anchor heads were connected with the J.K.S. panels by means of special connectingelements.

After installation of the J.K.S. panels they were filled with gravel (grain size 32/60 mm). These
works were carried out with an excavator, beginning from the top of slope (fig. 4).
A surface drainage was formed thereby which enables to lead away the joint water.
