A range of screw pile sizes
Screw piles vs concrete piles
There is an industry myth that screw piles Edmonton are always cheaper than concrete piles. The truth is that screw piles can be used for a wide range of projects and depending on the application may not be cheaper. However, here is a bold claim – screw piles are cheaper for lightly loaded structures. It’s a bold claim and i wrestled with myself whether or not it was true. I determined that when you zoom out and look at the.
This short animation explains the basics of screw piles and how they work
screw piles are a type of deep foundation that can be installed quickly with minimal noise and vibration. Screw piles are wound into the ground, much like a screw is wound into wood. This is an efficient means of installation and coupled with their mechanism of dispersing load, provides effective in-ground performance in a range of soils, including earthquake zones with liquefaction potential. How they work
the piles are made of circular hollow steel sections with one or more helices attached to them. Screw piles cut into the soil following a constant pitch, as opposed to auguring through it. The helical flights and shafts are specifically designed to suit the ground conditions.
Installing screw pile foundations takes considerably less time and machinery and usually costs less than installing a standard concrete foundation. Depending on the size of the piles , a range of different size of plant can be used for the installation , including hand-held machines. In many instances, only one machine is required for a steel , screw pile foundation installation. Screwed piling is installed with a hydraulic torque drive.
What distance is recommended between piles? What distance is recommended between piles?
Generally, we recommend to keep a distance between each pile of eight (8’) to ten (10’) feet, based on industry best practices. What load can a pile bear?
The loads or weight that a pile may carry is determined by the type of soil in which it is installed. The denser the soil, the higher the load bearing capacity will be. In very loose soil, the postech installer will decide between a bigger blade or extensions (to reach denser soil) so that the necessary torques will have been reached.

Helical piles 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 are advanced (screwed) into the ground with the application of torque.

It is simple and certified. When we install a goliathtech pile, we are continually digitally monitoring the torque values that are being created while the pile is being screwed into the ground. Much like when you install a screw into wood. The deeper you go the tougher it gets to install that screw into the wood therefore the higher torque it takes to install that screw. With a helical screw pile, higher torque equates to higher load capacity. So if for example you tell me that you need to have a single pile carry a load of 5000 lbs i would then install our pile to a depth that generates enough torque to provide 5000 lbs of load bearing capacity. We now know with certainty that your foundation will carry the load of your project. All of our torque values are digitally monitored and recorded. We take the guesswork out of your foundations.
Calculate screw piles for your project:
Screw piles are ideal for any project that requires a solid foundation with no risk of movement. Perfect for any deck or gazebo project, screw piles can even serve as a stable base under concrete. Thanks to our specialized machinery catered to residential and commercial applications, our screw piles are installed with minimal damage to existing landscaping and leave behind no mess. Compared to concrete, screw piles are installed in a fraction of the time. No more waiting for the concrete to cure – you can start building the moment the last pile is installed.
Little to no vibration and very little soil disturbance
t\These piles also resist upward forces. This is especially important in expansive soil. The helix is anchored in competent load bearing soil and the frictional forces along the shaft are negligible compared to the end bearing force. Screw piles are designed as a “true end bearing pile” only. Any minimal “skin friction” on the side of the pile shaft is not calculated into the piles required capacity. The amount of weight the pile can handle is governed by the bottom of the pile (helix plate). This creates confidence in the helical pier system to perform in soils where moisture levels change (which would change the parameters upon which any friction pile would work). Keeping in mind that the most common reason for foundation settlement is shrinkage of the soils due to moisture loss, the helical pier is the most practical choice for the engineering community.
Can your piles be installed in rock? Can your piles be installed in rock?
I’m in the early planning stages of building a deck on the back of the house. I’ve been intrigued with some of the advanced methods such as helical piles instead of multiple days of suck for concrete footers. In addition i’m also exploring paverdecks which are built with all steel construction (i-beams and “joists”). The coupling of the two technologies leaves me with very little susceptibility to rot. What i don’t know is what are the average costs for the helical pile system? i’m in the midwest (usa) in a neighborhood built in the 90s (farmland prior to that). I don’t expect much in the way of bedrock but rather a clay type of soil. I’m thinking i’ll need somewhere in and around 10 piles if i use steel beams. Otherwise, more like 15-20 for wood construction. Has anybody contracted or installed diy (not sure that’s feasible) this type of footing?.

If the term is unfamiliar, these are posts that are screwed into the ground to a suitable depth and left there as the structure. It works very well – you just need to be very accurate with placement and ensure that they are level. The top is not as big as a sonotube so you don’t have much wiggle room if they are installed out of square. Screw piles for decks can be purchased from building supply stores and they will have a hole for putting in a 2×4 for turning leverage. Those work pretty well unless there are a lot of rocks, in which case you are best to call a screw-pile contractor who drive them in with machines.
Can the piles be installed under an existing structure? Can the piles be installed under an existing structure?
We’re often asked if we can install posts under an existing structure. There are many different ways to do it, here’s a project we did for colby construction where we installed the piles through the top of the deck. The piles were added to support a new gazebo being added.

Deck foundations – there are two types of deck foundation we mainly use: concrete pillars or piers and techno metal post helical piles. A solid foundation is necessary for the construction of a deck, often built with multiple levels, sometimes a roof, the weight on the foundation can be very high. If you have an inadequate base, you risk costly repair expenditures. This same principle applies if there is a hot tub or other heavy objects on your deck. Concrete foundation pillar/piers (sonotubes).
A helical foundation (pile) is a factory manufactured steel foundation
consisting of a central shaft with one or more helical-shaped bearing
plates. The terms “foundation” or “pile” typically
refer to a compression application. Helical piles are referred to as helical
anchors when used in a tension application. Ram jack® manufactures helical piles and extensions in a wide array
of shaft diameters (2 ⅜”, 2 ⅞”, 3 ½” and 4 ½”). We have the facility to design and fabricate special orders as well, meeting.

Our extensive experience spans the residential, commercial, oil & gas, farm, utility and industrial markets. Hps driven steel piles are also part of our engineering and installation capabilities. Pine star provides optimized foundation designs for all load ranges and superstructure types using a combination of foundation technologies.
The primary purpose of a screw pile is to provide sturdy foundational support for various types of structures. They’re entrenched deep underneath the ground, allowing the weight that sits on top of the piles to be evenly dispersed. Usually, several piles are installed, which creates a platform for a building, bridge, or any other type heavy structure to sit on top of. When helical pile foundation systems are designed properly and installed correctly, they can support the tallest and heaviest buildings, platforms, roadways, bridges, and various other types of structures.
In most soil conditions the ultimate capacity of screw-piles and helical anchors will increase with time as a result of aging effects and thixotropy. This means that the capacity immediately after installation may actually be somewhat lower that the long-term aged capacity, which is conservative. A3. Minimal site disturbance
relative to most other types of construction activity involving the installation of driven piles, drilled shafts or other anchoring systems, the installation of screw- piles and helical anchors produces little to no disturbance of the site. Specifically, the installation of screw-piles and helical anchors typically produces no soil cuttings. This keeps the site clean, requires minimal cleanup at each installation locations after installation, and usually means lower project costs. An additional advantage is the low noise level associated with installation. Installation also produces minimal vibrations which can be important on some projects that are sensitive to construction vibrations. Since screw-piles and helical anchors have a small work footprint they also produce minimal disruption to adjacent structures. In cases of retrofitting or restoration, existing structures can often still be used while screw-piles or helical anchors are being installed. Since they produce no soil cuttings they can also be used efficiently at sites where contaminated soils may be encountered since the soils do not come to the ground surface.
The not so obvious problem with concrete foundations!
The short answer is yes! we tested numerous helical piles as an alternative to concrete foundations for our decks. Then we had to decide on which pile manufacturer to partner with. Concrete was clearly becoming an unreliable foundation for us. Concrete foundations were moving, heaving due to frost and failing. Some of the areas we work in did not have any issues, however areas such as aurora and oak ridges were proving to be problematic with concrete. We needed a reliable solution. We also needed a product that is fully acq approved for contact with treated lumber. Acq is highly corrosive when in contact with non approved metal.
Edmonton has a widespread number of complex and problematic soil conditions that are not well-suited to conventional concrete foundations and footings. Helical screw piles are a proven, cost-effective technology for supporting decks and buildings and underpinning failing structures.

*helical piles use one or more flights of helical plates that are torqued into a firm to dense soil to provide compression and tension capacity
**micropiles are typically designed for friction capacity only. However, end-bearing resistance can be included, depending on design requirements. ***driven piles have generally limited friction capacity as the displacement of the in-situ soils is limited and the strain compatibility between the pile and the soil is poor. ****caissons are drilled out and can be designed for friction. However, they require stiff-to-hard soils of significant length to develop reasonable capacities in friction.
