Canning Dam Western Australia
We manufactured and installed the worlds largest ground anchors.
The Canning Dam in WA required strengthening work to meet revised design and earthquake loadings. The work involved removing the top 3.8m of the existing dam wall and drilling down through the 70m high concrete dam plus up to a further 70m into the bedrock below. The top section of the wall was then rebuilt using reinforced concrete.
Across the 466m crest, 166 permanent, re-stressable ground anchors totalling nearly 13km in length were installed through the formed and drilled holes from the crest to be stressed and grouted deep into the foundation rock.
