Existing
Banks were excavated to 600mm stabilised and relayed
at a thickness of 400mm. Stabilisation was utilised
specifically to reduce seepage. This also enabled
the designers to reduce the amount of filtration
required because dispersion and erosion by wave
action was assessed as also being reduced by stabilisation.

These
irrigation channels have been stabilised over several
years on both the floor and banks in specific areas
where seepage has been identified as a problem.
We have completed several works in the Finlay-Berrigan
areas.

The
news in 1998 & 1999 reported an urgent concern
regarding the wall of the Hume Dam. A second wall
was constructed inside the existing wall. The construction
of this included 3 stabilised berms and the wall
exterior was treated with 150mm lime stabilised
clay for water proofing, improved linear shrinkage,
strength and durability.

Lime
stabilised lining system in situ in stabilisation
area. This was then pushed onto the wall and compacted
in a 200mm layer.

Completed
2 years ago, 150,000m2 150mm quicklime stabilisation.

The
then Fisher Stewart experiencing difficulty due
to the leaking storage facility found the answer
was to completing a 250mm layer of quicklime stabilisation
of the insitu material. This project was completed
10 years ago and is still in good operation.
