Fifteen years have passed since I was working at a dam site super
vising grouting work. That was not the first time that I had to car ry
out engineering geological investigations for several similar projects,
which always included testing programmes to find out the permeability of
the rock, and often I was in charge of grouting work. It thus attracted
my attention when this particular grouting programme did not run as
intended: most of the grout holes took only very little grout! It could
not be the aim of the invested work simply to drill holes and fill them
again without bringing about any further improvement. Fortunately, I had
the chance to be en gaged in many other grouting programmes in the
following years and used all these examples to analyse as thoroughly as
possible the permeability of the rocks being treated in view of their
grout ability. The more I studied, the stronger my conviction grew that
our rules which had decided the grouting of rock for many de cades
should be developed further, and therefore I occupied my self with
contributing some ideas for a new basis to investigation and judgment of
permeability of rock and for a more adequate application of this
technology.
