Helical Piles and Piers

Helical Piles, Piers, Anchors, Screws => Foundation Repair Equipment

Helical piles, often referred to as helix anchors, helical piers or helical piles are manufactured steel underpinnings that come in a wide array of shapes and sizes. Helical piles are often used in the repair and maintenance of building foundations characterized by problematic subsurface conditions.

Whether you are installing a new gazebo in your backyard or adding an entire new floor to your commercial space, SMR Supplies helical piles are guaranteed to provide the same results of conventional foundation systems. At SMR Supplies, our objective is to deliver the best quality while making the process easier and affordable for our clients. We are readily available to help you with any of your foundation piling projects. Delivering superior products and services is our priority.

How Are Helical Piles Installed?

Helical pier installation offer unique advantages not found in other conventional foundation systems. Completing a small addition or renovation project using a conventional system can take a surprisingly long time, require extensive efforts and typically cost substantially more per square foot than a new home construction. Instead of creating a mess like the other traditional foundation systems, helical piles require minimal excavation and can be completed in record time.

The helical anchors are mechanically rotated into the ground into varying depths using rotary hydraulics. They simply thread into the ground until they reach the desired depth. The depth of the helical pile depends on the load requirements of the building structure. If the building requires a deep foundation, additional helical anchor extensions are added as the pier is fastened into the ground. After the required depth is reached, the helical anchor extension is cut off and a load bearing plate or bracket is attached. When the process is completed, the building loads become attached to the building foundation and the weight is transferred to the stronger strata below, providing a simple and cost effective deep foundation system.

Where Can Helical Piers Be Used?

  • Helical piles make excellent foundations for projects that are located in environmentally sensitive areas where large excavation work is not an option, such as historical sites.
  • Helical piles are the safest option in areas with hills, variable soils, and poor foundational structures.
  • Helical piles can save a sinking home be securing and underpinning it to prevent further settling and from additional structural damage.
  • Helical pile installations are also used in projects that seek to maintain and improve on existing structural foundations. For example, a building that adds an additional floor, would have to add helical piers foundation to support the additional load that the new floor will exert on the building.
  • Helical piles can be used to fix cracks in drywall on the ceiling or walls, doors and windows that are sticking. They can also close gaps between walls and the ceiling to prevent nails coming out of the drywall.

What are the benefits of using Helical Piles in Comparison with other foundation systems?

  • Helical piers foundation is cost effective, it requires little to no concrete and can be performed in limited access situations.
  • Due to their innovative design helix anchors are lightweight and easy to install in tight spaces with limited access, such as narrow crawl spaces.
  • Helix anchors are easy to maneuver. They can be installed horizontally or at any angle to support a wide range of compressive loads.
  • Helical piers eliminate excavated drill spoil. The problem of what to do with excavated soil is eliminated because helical piles cause little if no soil disturbance.
  • Helical piers and helix anchors provide instant usability. The rapid installation offered by Helix anchors can result in overall cost savings in time and work hours.
  • Helical pile installation causes less noise pollution and can be installed with low noise levels and minimal vibrations.

FAQ

  1. How do I know how many helical piers will be needed to complete my helical pile installation project?SMR Supplies engineers and professionals will determine how many helical piers are required to complete your project. We start by conducting a general study of the building location and structure to properly estimate the depth, type and size of helical piers required. We also conduct is a soil test to determine which of our products should be used to guarantee you a stable helical pile foundation.
  2. How are helical anchors different from one another?The number of helixes, the diameter, pitch, thickness and the position on pile shaft of the helix anchor are all determined by a combination of conditions which include load requirements, geotechnical parameters, minimum life of the structure and environmental corrosion parameters.
  3. How long have helical piles been used in construction?Helical piles have been used in construction for over 200 years. Today, the method of helical piers foundation is used more frequently than other deep foundation procedures. More and more owners and developers everyday are beginning to request helical piles to complete their projects.
  4. Who invented helical screw piles?A blind English brick maker, Alexander Mitchell, invented the first helical screw piles in 1833. They were made of cast iron and were used to build lighthouses exposed to moderate seas or heavy ice fields.
  5. Is it true that helical piles are the most environmentally friendly deep foundation piling systems?Yes, they are! The helical piles contribute to the reduction of the overall carbon footprint of a project in many ways. Helical piles require fewer raw materials by weight and fewer truck trips, meaning that overall energy consumption for material transportation often can be reduced.
  6. Do helical piers rust?Often varying soil conditions may cause rust to eventually take place on the rods. SMR helical piers are galvanized to prevent rusting and delay it as long as possible. A general estimation is that helical piers can last more than 150 years in favorable soil conditions.
  7. What improvements will I see once the helical pile foundation is installed in my home?Often our clients see improvements immediately after the job is completed. We have witnessed doors that were previously jammed start to work correctly and cracks that were visible on the foundation will close and seal up.
