Pier Brackets
Pier bracket attachments
are installed by qualified and
trained helix steel pier
dealers/installers as specified
in the approved plans. For
interior piering purposes, a
portion of the
foundation slab is
removed and soil
excavated to create
“ L” shaped cavities
with nominal 30
inches (762mm) per
side square openings
to a depth of at least
18 inches (457 mm) below the bottom surface of
the foundation. For exterior
piering purposes, the
perimeter backfill soils
are removed to the bottom of
the foundation wall and the
above referenced “L”
shaped cavities are
formed. The exposed
foundation surfaces are
prepared and smoothly

pier attachment
(“lifting bracket”) without
obstruction on the bearing
or facing surfaces. The
attachments are pinned
firmly to the foundation by
driven or threaded fasteners.
