Screw Pile Install

ScrewPileInstallHeader

At Fence Tech Inc., we are not only Screw Pile installers we are also carpenters who understand where and why foundation support is needed for various projects. We install high quality engineered helical screw piles manufactured in a CWB Certified facility in Edmonton, Alberta that houses state-of-the-art equipment, providing one of the highest quality screw pile products on the market. These can be custom built to accommodate any application and ground conditions. Our screw piles are built to last as a solid permanent foundation method for many residential and commercial construction applications. Helical piling or screw piling is a long-standing, established foundation method, which has been used in projects for over 150 years. Screw foundations first appeared in the 1800’s as pile foundations for lighthouses and were extensively used for piers in harbors. The speed, non-invasive ease of install and superior foundation elements of screw piles were soon recognised by international construction authorities, including our provincial and federal building codes (Alberta Building Code A-4.2.7.1., National Building Code A-4.2.7.1.).

 

Engineering and Screw Pile Torque

Our screw piles are engineered and meet code for any deck where perScrewpiles7mits are required. Screw pile torque has a direct correlation with the load capacity of helical screw piles, as the install torque increases so does the load capacity of the pile. Most of our competition install these piles blind without torque monitoring systems in place, making it impossible for them know when they have hit good load bearing soil and determine the load capacity of the piles they install, leaving you with a foundation that might not handle the load and possibly sink.

We use top of the line PENGO/DIGGA screw pile drives and in-line relief pressure monitoring system which enables us to monitor the pressure at the drive head  and the back pressure returning to our tanks, using these readings we can determine based on our engineered allowable loads charts, that we are indeed into good load bearing soil and the exact load capacity of each pile we install, leaving you with a solid reliable foundation every time. If your deck requires a permit we can offer engineer stamped torque reports. Please let us know before the piles are installed if you require engineer reports for your permit.

Frost Line

We install our screw piles as deep as necessary to achieve the desired torque which will ensure the pile can handle it’s maximum potential load.  We also want to make certain the helix area of the pile is anchored well below the frost line. For fences and other structures that can float (move up and down with frost heave) getting below the frost line is not required, as they will move up with the frost and back down when the frost is out of the ground. However, if  you attach something that can float (like a deck on piles above the frost line) to something that is fixed and stationary i.e. a house, this is where you run into problems.  If for example your deck is attached to your home’s ledger board and the deck heaves because the piles are not below the frost line, this will cause the deck to raise while the house stays in the same position. This potentially could break the ledger board and loosen the joist hangers resulting in possible disconnection from the house.  This would create an unsafe deck that could in fact fall to the ground.

Although our national standard is to install 7 foot helical screw piles to get below a 6 foot frost line, Geotechnical engineers have found the frost line as low as 7.5  feet in some soil types around the Greater Edmonton Area.  This means you need a screw pile which is longer than 7 feet.  This  is why Fence Tech Inc. standard piles stocked are 8′ and 10’ piles ensuring the helix (bottom screw type plate which holds most of the bearing weight) is below the frost line and that there is enough pile above grade for the soil to move up and down around it. Every project has unique soil conditions and you can even have completely different soil conditions from one pile to other only a few feet away.  This is why our extendable pile system is a huge advantage over most of our competitors.

Screw Pile Applications

Fence Tech Inc. offers residential and commercial helical screw piling installation in the Edmonton Alberta Area. Screw piles are a great choice for residential and commercial applications as they cause minimal ground disturbance, are quickly installed, have superior foundation elements and can be built on immediately after installation. Our engineered helical screw piles are built from quality new steel material and modern robotic equipment creating a seamless finished product which will last longer than the lifetime of any structure. We offer our basic residential/light commercial  2 7/8 ” x 10′  or 12′ with  3/8″ x 12″ helix. For heavier applications we offer a 3 1/2″ x 10 or 12′ with a 3/8″ x 14″ helix and 4 1/2″ x 10 or 12′ c/w 1/2″ x 16″ helix. We also offer a 2 3/8″ x 10′ with 10′ helix which is a more affordable option for standard un-covered decks.  We stock various caps including 8″ flat with 1″ offset or 6″ saddle with 1″ offset for seating your beams, posts, concrete, etc. If required for certain rare ground conditions, our extensions can take the piles down to greater depths depending on the job at hand or engineering required.

Advantages of using our screw piles for your next project:

Minimal  disturbance to landscaping – Screw pile installations do not require any auguring or digging to install and can be installed for small residential jobs with our smaller machine utilizing turf safe tracks (our smaller machine is only 44″ wide). To install a conventional concrete pile, you would need a large machine which would damage landscaping, or not fit in a finished yard at all. 

No mess – Because screw piles are screwed into place using the integral helix system, no auguring is required, leaving no cleanup.  A concrete 12′ x 12″ pile which is required for most deck permits would leave approximately 4 wheel barrows of clay per pile, the clay removal itself is a huge labour/cost. 

Engineering & Building permits – Our screw piles can be used for permits where concrete piles are called for, in most cases 12″ x 12′ concrete piles. We offer engineer stamped drawings of our piles, torque to load graphs and complete foundation plans for provided project drawings which can be given to our customers when required for permit processing.

Custom welding & pile caps – We offer our standard flat 8″ slotted offset or 6″ saddle caps, these two cap styles work for the majority of our projects, however if you need a specific cap for almost any project we can custom build it. We can also weld custom caps to the piles on site with our mobile welding unit.

Custom Engineered piles – We can build our custom engineered piles to most pile and helix configurations

Piece of mind  – Get piece of mind knowing your newly installed screw piles will not move. We install our screw piles as deep as necessary to achieve the desired torque which will ensure the pile can handle it’s maximum potential load.  We also make certain the helix area of the pile is anchored well below the frost line, Although our national standard is to install 7 foot helical screw piles to get below a 6 foot frost line, Geotechnical engineers have found the frost line as low as 7.5  feet in some soil types around the Greater Edmonton Area.  This means you require a screw pile which is longer than 7 feet.  This  is why Fence Tech Inc. uses a minimum 10’ pile ensuring the helix (bottom screw type plate which holds most of the bearing weight) is well below the frost line.

Recycling – If years down the road you decide to change the layout of your deck, move your mobile home or change a sign location your screw piles can be moved or re-positioned by simply unscrewing  and re-installing in the new location.

Quick installation – Installation is quick. In most cases it takes less than 5 min/pile and with no downtime waiting for concrete to set, construction on your project can start the same day

Laser leveling option – With our optional laser leveling we can level and cut all piles to the same height so you can either place your beam directly on our 8″ offset pile caps, or cut all posts that make up the difference to the beam at the same height. This will safe you hours of labour and help in the process of building a professional built look.
