Project background
Berlin and Moscow are linked by the A2 Highway.
The longest stretch of this European road lies inPoland, spanning more than 100 km in length. From
here the route continues through Belarus (600 km),through the Russian federation (450 km) ﬁnallyending in Moscow.

Griltex Polska delivered DuPontTM Typar® SF 32, SF 37
and SF 65 along the Poznan-Nowy Tomysl section and for
the Poznan ring road.

DuPontTM Typar® SF Beneﬁts:

Qualitative high energy absorption of DuPontTM Typar® SF
ensured a good damage resistance level during theinstallation process. Motorway trenches were dug
alongside the motorway and lined with DuPontTMTypar® SF as a filter to prevent the contamination andthe clogging of the drainage system.
Utilising DuPontTM Typar® SF, guarantees a good longterm performance.

DuPontTM Typar® SF Signature:
DuPontTM Typar® SF: the quality geotextile for all
separation, ﬁltration and stabilization works.

Varying DuPontTM Typar® SF styles were used forseparation, filtration and stabilization in the construction

of the road section. In addition to the excellent
separation and filtration performance, the high initialmodulus of DuPontTM Typar® SF makes it the ideal
product to stabilise and reduce also rut formation.
