The entrance to the aquatic center, designed for the swimming
and diving competitions at the year 2000 Olympic Games in
Sydney Australia, is an impressive tunnel entry under a large
The berm itself is both a structural and architectural feature
of the entrance and as such required detailed attention as
to the finished aesthetics.
The embankment was constructed with compacted shale reinforced
with geogrids to satisfy the structural requirements, thus
the challenge was to accomodate and stabilize a topsoil face
on both sides to facilitate landscaping and therefore fulfill
the aesthetic requirements.
The TENAX TENWEB 3/300 geocells were selected based upon performance
and cost criteria. Performance data was developed by conducting
field trials tests simulating high rainfall intensity and
run off velocities.
Significant design input from TENAX engineers led to a satisfactory
installation technique including specification of pin type
and spacing to compensate for lack of anchor trenches due
to slope geometry and a slope length in excess of 35 m.
Where the slope length was greater than 10 m (ie. one panel
length) the panels were stapled (ie. each cell) end to end
to enable rapid installation by way of pulling the top panel
up the berm face with the other one following.
Once the panels were in place and the perimeter pegged, the
internal cells were pegged utilizing 12 mm galvanised steel
A total quantity of 9000 m2 TENAX TENWEB 3/300 geocells were utilized. Due to space constraints
at top of berm, all soil filling operations were undertaken
from the bottom. The upper portions of slope required the
utilization of a crane and kibble to facilitate filling.

The successfull installation and subsequent performances proved
the TENAX TENWEB system to be the most effective method of
stabilizing and revegetating the arid slope.
The installation furthermore set new benchmarks in respect
of maximum slope length of 35 m without the utilization of
