COMMERCIAL HELICAL PILES/HELICAL PIERS
MICROPILE, SCREW PILES, AND HELICAL PIERS
Helical piles, also known as helical piers are a factory-manufactured steel foundation system consisting of a central shaft with one or more helix-shaped bearing plates, commonly referred to as blades or flights, welded to the lead section. Extension shafts, with or without additional helix blades, are used to extend the pile to competent load-bearing soils and to achieve design depth and capacity. Brackets are used at the tops of the piles for attachment to structures, either for new construction or retrofit applications. Helical piles and helical piers are installed (screwed) into the ground through precision torque equipment.
DESIGN CONSIDERATIONS
Helical piles and anchors are designed such that most of the axial capacity of the pile is generated through bearing of the helix blades against the soil. The helix blades are typically spaced three diameters apart along the pile shaft to prevent one blade from contributing significant stress to the bearing soil of the adjacent blade. Significant stress influence is limited to a ‘bulb’ of soil within about two helix diameters from the bearing surface in the axial direction and one helix diameter from the center of the pile shaft in the lateral direction. Each helix blade therefore acts independently in bearing along the pile shaft.
Multiple piles have a center to center spacing at the helix depth of at least four (4) times the diameter of the largest helix blade. The tops of the piles may be closer at the ground surface but installed at a batter away from each other in order to meet the spacing criteria at the helix depth. For tension applications, the uppermost helix blade would be installed to a depth of at least twelve (12) diameters below the ground surface.
COMMERCIAL SCREW ANCHORS, HELICAL ANCHORS, TIE BACKS AND WALL STABILIZATION
Helical Anchors (also referred to as tiebacks and earth screws) provide lateral stability to foundation walls and retaining walls with unbalanced earth pressures.
They may also be used to anchor guide wires that support solar panel mounts, wind towers, power poles, and other high structures.
Helical anchors can be installed with hand-held equipment, mini-excavators, skid steers, backhoes, track hoes, or crane-supported rigs so the anchors can be installed in almost any application.
This versatility, along with the ability to immediately load and test the anchors, make helicals a convenient, smart and economical solution for a wide variety of projects.

HELICAL ANCHORS
Helical Anchors are a factory-manufactured steel foundation system consisting of a central shaft with one or more helix-shaped bearing plates, commonly referred to as blades, welded to the lead section.
Extension shafts, with or without additional helix plates, are used to extend the anchor into competent load-bearing soils. Helical anchors are advanced/screwed into the ground with the application of torque.
The terms helical piles, screw piles, helical piers, helical anchors, helix piers, and helix anchors are often used interchangeably by specifiers. However, the term “pier” more often refers to a helical foundation system loaded in axial compression, while the term “anchor” more often refers to a helical foundation system loaded in axial tension.
Our helical anchors feature blades manufactured with a true helix shape conforming to the geometry criteria. The leading and trailing edges of true helix blades are within one-quarter inch of parallel to each other and any radial measurement across the blade is perpendicular to the anchor shaft. A true helix shape along with proper alignment and spacing of the blades is critical to minimize soil disturbance during installation.

TIE BACKS
In use since the turn of the century, Tilt-Up construction isn’t new but the Pierpoint approach is. Using helical pier technology in Tilt-Up construction applications for the very first time, Pierpoint Systems is literally breaking new ground with our patented Tilt-Up, Insta-Brace Anchor. Over 15% of all industrial buildings in the United States are built using Tilt-Up methods, favored for its ultra long lifespan and durability. With Pierpoints Insta-Brace Anchor, buildings that last a lifetime are quicker and easier to build than ever before.
Created from a unique design consisting of three helix plates welded to a 1 ½“ square bar shaft, Pierpoint often uses the PierTech Systems Insta-Brace Anchor, which is made from superior strength steel. Typically stronger than steel used by other manufacturers, the shaft makes this the strongest helical anchor available with a yield strength of 95ksi and a tensile strength measured at 130 ksi.
While current Tilt-Up construction practice means concrete walls are created flat on the ground and then raised into position, the Insta-Brace Anchor expedites the entire process, eliminating traditional deadmen.
When your project is complete, the Brace Anchor can be removed and reused in future applications!
COMMERCIAL FOUNDATION NEW CONSTRUCTION & REPAIR
