What Are Helical Piles?

Helical Piles Foundation Systems are designed, tested, and proven for applications in areas with unstable soils

Helical Plates are welded to a steel casings. The Helical Piles are then mechanically rotated into the soil using  hydraulic presure.  and  are then attached  to the building foundation.

Homes built in beach areas on Long island and New Jersey are perfect locations for helical pile applications.

WHAT IS HELICAL PILE/ ANCHOR ?

A helical pile and anchor is an extendable deep pile foundation system with helical bearing plates welded to a central steel shaft. Load is transferred from the shaft to the soil through these bearing plates.

HISTORY

The usage of helical piles or screw piles and anchors in the construction dates back to nearly 200 years. In the 1830s, the earliest version of screw piles were used in England for moorings and foundations of lighthouse structure.

Today, helical piles are used in both compression and tension in construction industry as application of  piles & anchor due to the advancements in hydraulic motors and versatility of installation equipment.

Helical Piles and Helical Piers are The Same Product

Helical piles and helical piers are two terms that refer to the same product. These terms are commonly used and both refer to the exact same product.

Uses

Helical Piles are used to secure residential and commercial buildings, retaining walls and other deep foundation applications, and on new construction as well as repair and renovation work. Helical Piles are an affordable solution for foundation repair where soil conditions require deep piles to be installed. There are several advantages for using helical piers.

Advantages of Helical Piles

  1. They can be used on new construction projects, and will soon become mandatory in flood prone areas. They are perfect for new construction and any projects built on unstable soil. , contractors install helical piers under the existing foundation Rather than removing the existing foundation this not only save time but will save the homeowner money. This is both cost effective and environmentally friendly.
  2. Helical piles can be installed in small areas we have portable equipment that can be used in very small spaces. Compared to other pile and pier methods another advantage to helical piles is that in most cases no concrete is used, therefore the next phase of construction can begin immediately
  3. Helical piers have changed the way foundations are designed and built. Helical steel piers can be installed in place of conventional driven wood, steel, auger cast, and caissons. These piers are faster and install with a minimal amount of landscaping damage. A hydraulic auger mounted on a skid steer or mini-excavator is used to screw in the helical pile thru the soil as torque is monitored to achieve required load capacities.
  4. This environmentally friendly system provides a clean and quick installation procedure to keep projects on schedule. A steel plate is fastened on top of the pile and encased into the new concrete foundation. The pile can be loaded immediately.
  5. Unlimited uses for helical piles: Home extensions, underpinning existing foundation, concrete footings, foundations, and retaining walls. As well as Concrete slabs, decks piers, generator pads, commercial projects, and reinforce existing foundation for second story additions.

Where Can Helical Piles Be Installed ?

Helical Piles are steel shafts with a series of low-pitched circular steel helical plates welded at strategic positions along the shaft. The plates give the foundation both tension and compression bearing capacity which enables them to be used for a wide range of applications across many industries and sectors.

The piles can be connected in groups using a steel load transfer grillage and are screwed directly into the ground by machine-mounted hydraulic or electrically powered drilling equipment.  Helical Piles make the use of concrete for foundations a thing of the past.

Our engineers design helical piles to suit the ground conditions at every individual site. This technology is one of the fastest foundation solutions in existence and this, combined with reduced environmental impact and ease of installation in restricted access sites, is the reason that this technology is so popular and so widely used today.

Depending on location and the solution designed, helical piles can be installed:

  • Raked at angles up to 45°
  • Protruding from the ground or buried
  • In any soil
  • To support structures in compression and tension
  • At grade, on embankments, and in cuttings
  • In low temperatures – unlike concrete
  • In bespoke situations to suit your requirements
