NEW CONSTRUCTION
Piles are installed on 5' to 7'
centers after the foundation is formed. The pile
installs like a lag screw so no soil is removed. Two
mats of rebar are required in the foundation.
Helical piles can be installed where auger trucks
cannot go. Installation in wet areas is possible
with tracked installers. Helical pile installation
is rapid enough to precede concrete placement and
involves minimal disturbance. Installers can reach
most areas without the need to cross the foundation
forms. Helical piles can be used for other bearing
problems and can be installed in limited headroom.

TIEBACKS
Helical tiebacks can be used in tension applications
to anchor retaining walls. Helical tiebacks have
shorter bond lengths than grouted ones, so they can
be used where it is necessary to not encroach beyond
the property line.
The anchors are installed in tie
points in the soldier beams for a clean look.
Combined with horizontal pipes, helical tiebacks
allow anchoring of MSE geogrid walls without
excessive excavation.

UNDERPINNING
Underpinning is used when an
existing structure has failed and support must be
restored and the house returned to level.
Underpinning brackets allow transferring of the
structure load to the newly installed piles. They can be installed with minimal
destruction to landscaping.
Rigid piles will stand unsupported.
Hand units allow installation inside buildings.
