At Mühlau, just to the north of Innsbruck<br />
(Austria), runs a channel in which an avalanche<br />
dam has been constructed. It consists of five<br />
parallel concrete blocks with a reinforced slope<br />
on either side based on <strong>TenCate</strong> <strong>geosynthetics</strong>.<br />
This natural channel serves as a discharge<br />
for avalanches and in spring for the large<br />
quantities of meltwater. This ensures that<br />
the villages of Mühlau and Arzl and - in the<br />
worst-case scenario - the city of Innsbruck<br />
itself are not overtaken by this natural disaster.<br />
The concrete structure serves to considerably<br />
lessen the destructive force of the avalanche.<br />
The reinforced earth slope on either side of<br />
it blocks the passage of snow and water.<br />
This avalanche dam is 23 metres high and<br />
22 metres wide at its base. The structure is<br />
designed to resist a pressure of 20 tons per m².<br />

Avalanches and large quantities of meltwater are being guided safely away from<br />
Innsbruck, in part thanks to the use of a system incorporating <strong>TenCate</strong> <strong>geosynthetics</strong>.<br />
concrete are not viable: the costs of such a<br />
structure and of transporting building materials<br />
to such a remote and difficult terrain would<br />
be too high. Moreover, the area is popular<br />
with tourists, which is why providing a natural<br />
appearance is by far the preferred solution.<br />
This has been successful, in part thanks to the<br />
use of <strong>TenCate</strong> Polyfelt Polyslope ® S systems,<br />
an environmentally-fri<strong>end</strong>ly and attractively<br />
priced system for the construction of retaining<br />
walls. It consists of <strong>geosynthetics</strong> for<br />
reinforcement (<strong>TenCate</strong> Polyfelt® and <strong>TenCate</strong><br />
Miragrid ® ), a preformed steel grid (shuttering),<br />
<strong>TenCate</strong> Polyfelt ® erosion protection and<br />
locally available soil as filling. This ensures<br />
that a green bank covered in vegetation will<br />
grow rapidly and have a natural appearance.<br />
