Southern Industrial Piling provides helical piling installation services. Helical piles are a deep foundation system consisting of a central steel shaft with helical bearing plates that screw into the ground to transfer loads with minimal soil disturbance. They can be installed quickly in difficult access areas and conditions and allow for immediate loading. Helical piles offer advantages over other foundation types including reduced schedule, no cure time, installability in tight spaces, lower costs, and ability to install in any weather or site condition.

2. What are Helical Piles
A helical pile is an extendable steel, deep foundation
system. Consisting of helical bearing plates welded to
a central steel shaft. Load is transferred from the shaft
to the soil through these bearing plates.
Sections are joined with bolted couplings.
Installation depth is limited only by soil density and
practicality based on economics.
The bearing plates are true helical shapes, the helices
do not auger into the soil but rather screws down with
minimal soil disturbance.

4. Helical Pile Deep Foundation Features:
• Use in both compression and tension
• Load immediately after installation
• Pre‐engineered & manufactured. Minimum quality
control concerns
• Pile integrity measurable during installation
• Minimal equipment and crew needed for construction
• No excavation or soil disturbance
• Allows minimum or no concrete use
• Many options for pile caps
• Install in almost any weather condition
• Install in high water table
• Install quickly
• Smaller equipment and crew means more economical
• Much more than a choice of last resort.

5. International Building Code Chapter 18 -Soils and
Foundations
• HELICAL PILE. Manufactured steel deep foundation
element consisting of a central shaft and one or more
helical bearing plates. A helical pile is installed by rotating
it into the ground. Each helical bearing plate is formed
into a screw thread with uniform defined pitch.
ICC AC358 Acceptance Criteria for Helical Foundation
Systems and Devices
• ICC AC358 -1.4.2 Helical Foundation System: A factory
manufactured steel foundation designed to resist axial
compression, axial tension, and/or lateral loads from
structures, consisting of a central shaft with one or more
helical-shaped bearing plates, extension shafts, and a
bracket that allow for attachment to structures. The
shafts with helix bearing plates are screwed into the
ground by application of torsion and the shaft is extended
until a desired depth or a suitable soil or bedrock bearing
stratum is reached.
Acceptable per Building Code

6. Why us instead of ACIP or Driven Piles?
 Faster installation, cuts schedule substantially
 No cure time required; Immediately loadable.
 Installable in tight access and low clearances
 Much lower mobilization cost
 Minimal equipment and crew needed. No spoils or
rebar crews required.
 No installation vibration concerns
 Install in any weather & site conditions
 Not dependent on 3rd party mat’l & crews
 No spoils & wasted materials disposal cost
 Piles removable and reusable for temporary
installations

Duck Camp in undisclosed location!!
“From pile installation to in the dry in
3 weeks. Pretty amazing.” owner
Height above grade changed
three times during proposal.
Required structural engineer
assistance to allow for lateral
loads and buckling
evaluation.
Best choice for multiple reasons:
Concrete trucks couldn’t get to
site, soil expansive, time crunch
on schedule, inaccessible to
large equipment, duck season
just around the corner.

17. We’re Not Just Commercial and Industrial!
Use us for RESIDENTIAL
• Invest in helical piles up front and avoid
expensive repairs later.
• Expansive Soils – Helicals are best solution

18. Expansive Soils
• Helicals are Best
Solution
• Recommendations
– Install single helix or
assure all helix can be
installed in stable soil.
– Minimum installation
torque 4,000 FT-LB, all
helices
– Use of void form under
pile caps, grade beams

19. Shale, Rock or other hard layers
• End bearing on pile is
acceptable.
• Must be evaluated if there
will be tension loads.
• Is hard layer capable of
supporting loads?

20. How Long Do They Last???
• Depends on
soil pH and
resistivity
• >75 years is
common.
40 yrs 80 yrs 160 yrs shaft life (1/8” loss)
16 yrs 40 yrs 160 yrs shaft life (1/8” loss)

21. Lateral Loads Analysis & Management
• Lateral Load Management;
– Shaft section selection
– Transitioned piles
– Concrete/Steel Caps –Passive
soil resistance
– Soil stabilizition, admix
– Battered piles
