5 Things You Didn’t Know About Screw Piles
When you’re constructing a building around other structures, you have to take their proximity into consideration. Your foreman will have to look at the vibrations that are created by the construction equipment and ensure they’re not too violent. If they are, they can damage the foundations of surrounding structures. Screw piles create very little vibrations during their installation. They start at a low of 1mm when installed without any obstacles. When the pile is forced to go through an obstacle, it can reach highs of 5mm. Anything over 10 is what can create damage to a structure.
So, you never have to worry about monitoring vibrations during the construction process when using helical piles.
The total number of piles and their pitch is calculated for the construction of a one-story building with a size of 7×7 m. The approximate weight of consumables (roof, timber, cladding, etc. ) is 25,000 kg. Payload: 7x7x150 (accepted value for residential premises) = 7350 kg. Snow load: 7x7x180 (constant) = 8820 kg. Calculation of the total mass of the load on the foundation: 25000 + 7350 + 8820 = 41170 kg. This value must be multiplied by a safety factor of 1. 1. We get 45287 kg. Now it remains to divide the resulting value by the size of the load per one pile (for example, a screw): 45287/2000 = 22. 6435. After rounding, we get 23. Such a number of supports you will need. Installation step – 1. 2 m.

f anything the last decade has taught us, it’s that a lot of what our forbearers did was far better for the environment and us as a whole than modern techniques. It seems that this is even true in the case of geotechnical engineering and the construction of foundations. The screw piles or pile foundation first came to prominence at the end of the 19th century and became one of the most well-known forms of foundation used throughout the world. It was simple, fast, effective and didn’t require the demands alternatives such as concrete does.
If you’re not familiar with a screw pile, it’s quite a simple but a very effective mechanism. Essentially, it’s a screw that’s wound into the ground via some earthmoving equipment with a hydraulic attachment. On one end of the pile is a screw or helix and the other is attached to the building. This form of ground anchoring system works with a variety of ground conditions and buildings of all shapes and sizes.

1. Screw piles are perhaps the most underrated foundation engineering feat of the 19th century
original patent application, us3986 by alexander mitchell. Screw piles enabled lighthouses to be built in shallow water under challenging soil conditions. At a time with limited engineering techniques, these lighthouses were an integral part of getting ships to harbour safely. Screw piles also enabled bridges and piers to be constructed in varying soil density, which changed the recreation patterns of society and boosted the economy. Towards the end of the century, screw piles were also used to prevent existing foundations from sinking, such as the town hall in great yarmouth, uk in 1882. Overall, their invention changed the face of our nation’s infrastructure, providing engineering techniques that enabled social and economic growth.
2. Screw piles were used for building and removing foundations for the 2012 London Olympics.
Screw piles essentially provide deep-rooted foundations for structures. They’re designed for rapid construction, on any scale. They can be used for garden rooms , deck building, or seriously large-scale commercial projects. Looking for examples? many of the 2012 london olympic sites, including the bmx venue , were constructed upon screw pile foundations.

this is a good foundation for any size shed or house; home built or prefab. Great for any soil type too. It is similar to concrete pier and post and beam construction. The screw piles are galvanized steel posts with a screw end. They come in a choice of lengths and diameters. Some need a small excavator with a special attachment to screw them into the ground to the frost line. Other types use a special handheld powered screwdriver – hope you have strong wrists. The screw helps to prevent vertical frost lift. There is also minimal settling since the soil is undisturbed by digging.
Helical screw piles were first utilized in the mid-nineteenth century as a major improvement over the traditional straight pile designs that ruled at the time. Their first applications were mainly as foundations for marine structures such as ship moorings, harbor piers, and lighthouses. Throughout the next century, helical pile patents spread to the agricultural industry to improve fencing designs and to the erection of utility towers and pipelines. Eventually they also spread to the general construction of new structures as well as retrofitting to improve the stability of existing structures. Helical piles have adapted to emerging trends and changes in the needs of engineers over the last century, and today they come in a wide range of shapes and sizes.
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. 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 pile loaded in axial compression, while the term ‘anchor’ more often refers to a helical pile loaded in axial tension.
5. Screw Piles were originally installed completely by hand, even in open sea.
Lower mobilization costs
screw pile foundations can typically be installed using an excavator or skid-steer, eliminating the high mobilization costs associated with equipment used to install driven piles, drilled shafts and auger-cast piles.

the winnipeg, manitoba region is well know for its expansive soils and the damage it can do to foundations. Screw piles are unique in that the bearing plate (helix) can be placed below the depth of seasonal moisture variation. The swell force on a shaft is directly proportional to the surface area in contact between the soil and the shaft. Since helical pier foundations have relatively small, smooth shafts compared to other foundations such as concrete, the uplift forces are much smaller and easily resisted by the helix anchored below.
In the early days, screw piles were installed by hand or with pony power. In fact, in the early 19th century, that’s how all installations were made, even those in open water. Today, most large-scale installations are made by bobcats, excavators, or mast mounted cranes with hydraulic attachments, depending on the size of the piles. For smaller diy projects, you can install them by hand with an installation kit, or with an electric handheld machine.

One of the biggest complaints that construction foremen get about their sites is the noise they create. This holds especially true when they’re working in areas that are heavily surrounded by other structures. Screw piles are a great way to help prevent noise complaints from neighboring properties. At their highest, piles reach 80db when installed. This is still considered a safe level without any hearing consequences. This is not only great for keeping complaints from neighboring properties at bay, but it’s safer for the construction crew that is installing the piles. They won’t need to wear any sort of hearing protection device.
In this article i like to share with you my experience with one of the natural cures for piles. I shall not write in detailed about piles, because this article is all about natural cure for piles using dried figs, and not on the subject of piles. There are hundreds of supposedly effective cures for piles using natural ingredients. There are so many popular herbs, vegetables and fruits that are believed to be able to cure piles. You can just search through the internet and will be surprised to find so many of them such as onion, turnip, bitter gourd, radish, mango seed, tobacco leaf, ginger, rice, wheat grass, sesame seeds, banana, dried fig and what have you. I suppose not all are genuine cures, while some may be effective to some lucky ones. On the whole i think the chance of striking the “bull’s eye” is pretty remote. Still there is no harm trying out a few. So i chose the dried figs treatment. Before going into the dried fig treatment, let’s read a bit about what piles are.
This one is pretty simple to answer: on the most basic level, a screw pile (or helical pier) is a steel tube–sporting permanently attached helical blades–that is twisted into the ground like a giant screw. These piles then act as foundations for any structure built on top of them.
This makes screw pilings the ideal choice for your next construction project.
Our experienced installation pros provide the very best in engineered piling foundation installation or foundation repair at amazing value.
The Right Choice
With the type of soil conditions found in and around the City of Champions, building a lasting and stable foundation for you project can be a challenge.
Choosing helical piles to support the foundation of your project can be the answer.
Engineered pilings are constructed with a hollow steel tube affixed with one or several helixes.
These helical plates allow for a more effective bearing load capacity when soil can be problematic.
During metal post installation, torque is monitored.
If the installation torque is unsatisfactory then extensions can be added to go deeper and provide greater support.
As screw pile equipment and technology has improved over the years we have advanced along with it.
It has become more common in Alberta to utilize screw pilings vs concrete.
Compact skid steers and high torque drive heads make building foundations possible and easy in any location.
Often providing an economical advantage over other piling alternatives.

Equipped with a slow speed high torque drive head, our 36″ wide install machine can drive 2-7/8″ and 3-1/2″ piles in almost any location.
Installation is fast and easy with no excavating or backfill with no soil to be hauled away after installation.
Whether you need screw piles for decks or any other residential application, each piling can be installed with minimal impact to the ground or to the surrounding area.
Commercial
Continuing beyond that of residential jobs, the commercial applications of screw piles are many.
This is mainly because of the the affordability and versatility of helical pile installation.
Yes, screw piles can be used for foundations much like that of residential projects but while meeting the higher requirements of commercial building codes.
The fast and easy installation allows commercial renovators and developers to employ screw pilings for more structures like signs, light standards, roof structures, grade beams, retaining walls and sidewalks.
Also their cost effective and quick installation is perfect for larger commercial jobs where profitability and scheduling are key.
Installation Done Right
Installing screw piles is fast, economical and non-invasive.
When installed with the right equipment, there is very little disturbance to the soil.
This means there is no excavating or backfill required and more foundation stability.
The hydraulic heads that we use are high torque and turn at a slow speed.
These drive heads are specifically design for use with engineered screw pilings.
Often contractors will use drive heads meant for augers.
These drive heads spin too fast and disturb the soil, causing instability with potential for frost jacking.
Additionally auger heads only put out low torque.
This means these heads may not be able to achieve any engineered pile load requirements.
Trust the best, our install crews at The Edmonton Screw Pile Pros use only the right install equipment and drive heads.
This means when our people install your piles, the torque is properly applied and monitored.
Advantages
Fast Installation.
With little preparation or cleanup required.
Immediate load bearing capacity.
Unlike concrete footings, the screw-anchors can be loaded immediately after installation.
Minimal ground disturbance.
As the posts do not displace the soil during installation.
The ground in which they are put into is not disturbed leaving the soil more stable
Load Capacity Verification.
During installation the torque is monitored and recorded.
This indicates the soil condition in which the pilings are installed and indicated how much weight the screw pile can hold.
Increase Load Capacity.
In the field if the required installation torque is not met, helical plates or piling extensions can be added.
Going deeper with extensions or adding helical plates can increase the torque to meet the engineering specifications
No Frost Heaving.
As all metal posts are installed well below the frost line with the load bearing helical plate typically at the deepest point.
Screw piles are resistant to frost heaving.
No excavating.
Because the posts simply twist into the soil there is no requirement to dig or drill any holes.
This saves time and money
