Construction—APAC—Australia—Slope Stabilizations
DYWIDAG GRP Anchors stabilize Slopes along Coramba Road
in New South Wales
The scenic area between the town of Dorrigo and the seaport Coffs Harbour
in New South Wales, Australia, is a magnet for tourism. Coramba Road,
which links both towns, is especially popular with motorcyclists because
of its breathtaking scenery.
Unfortunately, due to the high average rainfall,
this area is prone to ground movements
that have repeatedly damaged the road.
As a result, the New South Wales Government
has commissioned the upgrade of a number of
roads in the northern New South Wales area.
In this program, past and potential slip areas
will be stabilized and protected from future
damage caused by excessive rainfall.
In 2014, a part of Coramba Road 5km east
of Dorrigo was also marked as a potential slip
area. To stabilize this region, DSI Australia
supplied DYWIDAG GRP Anchors that were
ideal for this project because of their ease of
handling and long design life.
