Innovative Construction using Geosynthetics – Pros and Cons<br />
In the last 10 to 15 years, constructing using geosynethetics<br />
has seen unparalleled growth. The total production<br />
of geosynthetics in Germany has now reached ca.<br />
80...100 Mio./m², or in other words, a worth of 150...200<br />
Mio €. These products are used in road construction,<br />
earth moving and foundation engineering. The main area<br />
of application is the area of geo-technic. Using geosynthetics,<br />
structures have been built which would have been<br />
impossible using the hitherto conventional methods of<br />
construction, for example, Europe’s tallest inclined wall<br />
with green facing:<br />
now dominate numerous fields of application, for example,<br />
spanning sink holes:<br />
B180 n Aschersleben<br />
Iserlohn II (Construction height 24m, Inclination 28°, Length 400<br />
m)<br />
The application of columns with geosynthetic jackets, or<br />
using geosynthetics to span the top of long or circular<br />
supporting elements on the new high speed rail-line (a<br />
new section for express passenger trains) are further<br />
examples. The diversity of commonly available products<br />
and the multitude of possible fields of application speaks<br />
for itself. But despite all the positive tendencies and developments<br />
which have come hand in hand with this<br />
method of construction, some critical comments are necessary.<br />
One can no longer imagine the area of foundation construction<br />
without geosynthetics, an area in which they<br />

Future prospects:<br />
Cheap constructions?<br />
Constructing using geosynthetics does not mean cheap.<br />
The fallacy of a simple construction method, that ostensible<br />
building errors will be absorbed by this good-natured<br />
material, is often first recognised too late by customer and<br />
constructor alike. Just like all others, this method of construction<br />
requires detailed design and intensive engineering<br />
treatment. Geosynthetics are not a panacea for<br />
erroneous pricing or mistakes in the design. The<br />
method of construction has now acquired its place in the<br />
geotechnics, earth management and foundation design<br />
and comes, just like all other methods of constructions,<br />
with its own advantages and disadvantages. The responsibility<br />
of knowing when and where this method of construction<br />
is to be recommended rests in the hands of the<br />
engineer, the consultant and the manufacturer. A wrong<br />
application of geosynthetics, or an unmaintainable generalisation,<br />
for example ‘…we save on soil replacement by<br />
using geosynthetics…’, cast a shadow on the entire<br />
method of construction. One does not have to search<br />
long to find examples of inappropriate application.<br />
Be that as it may with the critical aspects mentioned<br />
above, the geosynthetic sector will continue to expand<br />
with numerous alternative solutions into further fields of<br />
application. This conference has the goal of contributing<br />
in a small way to a special field of application and developing<br />
new stimuli and ideas for the application of geosynthetics,<br />
particularly when subjected to non-stationary<br />
(dynamic) loading. Interesting contributions, good and<br />
interesting discussions as well as an excellent venue<br />
kindle the hopes of a valuable conference for all involved.<br />

Design Standards?<br />
A further problematic area to be discussed at this point is<br />
the legal situation and industry standards. For applying<br />
geosynthetics in a construction. The current design concepts<br />
published in Germany are not based on the eagerly<br />
awaited partial security concept (Partialsicherheitskonzept)<br />
and industry standard 1054. This standard has not<br />
yet been introduced for construction supervision.<br />
This results in legal consequences for designer, constructor<br />
and retailer. Every retailer would be well-advised to<br />
consider these consequences just as he should seek<br />
neutral information about this method of construction. It<br />
should be the case that the optimal product is chosen for<br />
the particular purpose. The spectrum of available geosynthetics<br />
allows a selection from a multitude of products<br />
which can be selected according to the dictates of technical<br />
understanding and economical considerations.<br />
