provide a third option and fundamentally
change the way industry thinks
about foundations.
Now in Canada, EBI has worked
on more than 200 successful projects
around the globe and has more than
25,000 Expander Body (EB) units in the
ground to date. The product is patented
or trademarked in 188 countries and
has conservatively saved organizations
in excess of 30 per cent in costs and
more than 40 per cent of labour when
compared to traditional methods.
The EB pile technology was first
developed by Swedish engineer Bo
Skogberg in the 1980s before it was
purchased a decade later by Prof.
Mario Terceros, who saw the potential
of the product to increase the capacity
of bored piles in loose to dense soils.
Over the next decade, the EB technology
was advanced in Bolivia, making it
more adaptable to different pile installation
processes and soil densities, and
providing broader savings for deep
foundation projects internationally.
“We have surveyed hundreds of
engineering companies, project development
companies and design/build
companies to ask them what challenges
they routinely face when it
comes to foundations,” said Richard
“Biff ” Heringer, general manager/VP
sales at EBI. “The responses always
come back to the same three things:
cost, time and capacity. The EB significantly
saves in regard to cost and
time, and for capacity, it typically
improves bearing loads for piles by
as much as three times. For tie backs
and anchors, the increase can be more
than seven times.”
Before expansion, the EB looks
like a long tube of folded sheet
metal attached to a steel pipe. The
EB-equipped pile (typically placed at
the pile toe) is inserted into the soil to
the required depth (either through a
pre-drilled hole by self-drilling or driving)
and a grout pump inflates the EB
through a high-pressure grouting conduit.
After expansion, the EB appears
similar to a large, water-tight metal
balloon filled with grout.
“You use the EB product itself
to gain the capacity you need,” said
Heringer. “When you expand the EB,
the soil around it becomes much
denser and this densification, as well
as the enlarged toe area, considerably
increases the pile bearing or tieback
tension resistance.”
The EB is so versatile that it can
be installed vertically, horizontally or
inclined, and is completely reliable
as a rock-solid anchor. In addition to
improving the bearing of piles, the
remarkable adaptability of the EB
also allows the product to be used for
a variety of other applications, such
as, but not limited to: anchoring/
ground stabilization, tunnelling and
buoyancy control.
EBI recently visited a project in
Victoria, B.C., where engineers were
struggling with tieback issues concerning
extremely soft blue marine
clay. Multiple conventional solutions
failed, reaching tension resistances
