of the primary panel is typically three times the width of
the Hydromill, approximately 7.3 metres long.
Once the Primary Panels were excavated and
poured, Keller was able to commence ‘Closure Panels’
installation, a single-bite panel that overcut 25 to 30
centimetres of concrete to create the watertight panel
joint. As part of the project, Keller also incorporated a
special ‘TShape-Panel’ (both Primary and Closure) in
the design along the West Plug Wall, which increased
the stiffness of the wall structure to act as the temporary
bulkhead.
At Port Lands, bentonite powder (a specialized clay
used in several geotechnical applications to support the
excavation process) was mixed with water in a colloidal
mixer to a specific engineer-design specification, left
to hydrate for 12 hours and then pumped to the panel
as bentonite slurry. The slurry supports the excavation
walls to allow Keller to excavate to depths up to 44
metres with less than 0.5 per cent vertical deviation at
the tip of the panel on this project.
A large-scale desanding and treatment process was
at the heart of Keller’s Port Lands operations, producing,
recycling and redistributing the bentonite slurry to
the excavation site. It was also critical in maintaining
a slurry head within the guide wall – and specifically
above the known water table – to avoid panel collapse
during excavation.
“Our desander separates sand from the bentonite
slurry by pumping the slurry over a series of shaker

PROJECT SPOTLIGHT
Keller’s BC 40 Hydromill
“The BC 40 Hydromill was the
workhorse of our operations
and performed phenomenally
through the sand, silts, soft clay
and shale bedrock.”
