Helical Piles

If "helicals" are a new term to you, prepare to be impressed. These intra-earth over-sized "screws" are precisely drilled into the earth, unifying your above-grade foundation to the most-foundationally securing depths of the earth. Bypassing any topical layers of shifting sand, wet land, tree roots and more, advanced science lets us analyze your building's specific land and mass traits to solve your deepest foundation issues with precise planning and execution. There's no drawback to these guys: their soil spoils are minimum, they won't bother your neighbor with patience-testing noise, and their brag-worthy maneuverability allows them to fit into the tightest of lots.

Gladly. As helicals' penetrates the earth's surface, each blade slithers into the soil increasing torque exponentially as it anchors more deeply into the earth. Structural engineering deems the diameter of the helicals, the depths they extend, and the count the project requires; we both extricate such decisions independently as well as work with structural engineers and architects if a team is already in place. Helicals deliver a substantial security that isn't necessary for modest-sized inland residential projects, but is mostly called upon for coastal properties with trying winds and storms that can surprisingly uproot all that you imagined to be grounded as well as commercial properties (of any location) where the owner wants to get things done right for the first - or last - time.

Helical piles are an economical alternative to wood and steel driven piles or concrete watertight chambers. They cut down installation time as well as site clean-up, translating to mean your project's turnaround time is minimal and cost-sympathetic. Also, installation equipment doesn't cause disruptive vibrations despite the girth these screws deliver, and can be installed virtually year-round: not even frozen ground stops them.

Helical services include but are not limited to:

  • Underpinning structures (residential and commercial)
  • Tiebacks, wall-anchors and earth-anchors for slope stabilization
  • Boardwalk and pedestrian walkways or bridges (yes! Even these helicals are excellent for securing)
  • Seawalls and bulkheads
  • Pipeline and utility tie-downs
  • Shoring, both temporary and permanent
  • Concrete-less foundations
  • Deep foundations for new construction

Foundation damage – whether it is from poor soil conditions, moisture and leaks, tree roots, poor construction, or another reason – can lead to major problems within the home and compromise stability. The main purpose of a foundation is to provide support for the structure itself, and thus if left unchecked damage can lead to cracks in walls and tiles, bowed walls, sloping floors and even make it difficult to shut door and windows. Should you find your foundation is damaged, one solution towards stabilization is the installation of helical piles. These are sometimes referred to as: helical anchors, helicals, screw piles or earth anchors.

 

We love doing helical installation; it's rewarding work and produces excellent results. Give us a call or shoot us an email if you'd like to following this interest further, obligation-free.

How Does a Helical Pile Work?
A helical pile is a steel shaft with blades attached in a spiral pattern, similar to a typical wood screw. The pile is attached to the foundation at one end, and then “screwed” into the ground below the frost line using a hydraulic torque motor in intervals to disperse the structure’s weight until the predetermined load capacity is achieved. As the blade penetrates the earth’s surface, each blade cuts downward into the soil, increasing torque as it anchors into the earth. Typically, helical piles are installed between ten and thirty feet below ground level, and can hold a weight of up to five hundred tons. Depending on the soil conditions on site, more helical blades may be added with an engineered dual cutting edge.

Benefits of Helical Piles

Helical Piles are an economical alternative to wood and steel driven piles or concrete caissons. Unlike the heavy duty equipment and timely processes required to install wooden piling or other deep foundations, helical piles don’t create spoils that must be removed or distributed within the job site. Installation equipment is relatively small and easily maneuverable, providing the benefit of fast installation, with minimal turnaround time on your project. Installation equipment also doesn’t cause vibrations that may be disruptive to soil or other surrounding structures and can be installed in virtually any type of weather – even in the freezing cold winter or blistering summer heat.

As they are a pre-engineered system, the capacity-to-torque ratio produces completely predictable installation results and the tilt-up wall anchors are temporary and reusable.  Additionally, helical piles come in a wide variety of piles and capacities – ranging from eight tons to 200 tons. Single and dual cutting edged helixes from 8” to 24” in diameter and shafts from 2.87” to 5.72”.
