Extendable Helical Screw Piles Available in Winnipeg and Rural Manitoba

Question:  How deep do you install your screw piles?

Answer:  As deep as necessary to achieve the desired capacity and to ensure the helical is anchored well below the frost line.

Although the national standard is to install 7 foot screw piles to get below a 6 foot frost line, Postech Winnipeg recognizes the unique Manitoba climate and soil and chooses to only carry 10 foot piles.  Geotechnical engineers have found the frost line creep as low as 8 feet in and around Winnipeg.  This means you need a screw pile which is longer than 7 feet and longer than even 8 feet if you want to guarantee the helical is well below the frost line and that there is enough pile above grade for the soil to move up and down upon.

10 foot screw pile extension added to a 10 foot screw pile for a deep installation.

The fact is that every project has unique soil conditions and you can even have completely different soil conditions from one pile to another only 10 feet away.  This is why it is a huge advantage having a screw pile system which is extendable.

Question:  When do screw piles need to be extended?

Answer:  There are several reasons you might want to extend a screw pile which include but are not limited to: 1) You want to reach bedrock or hard-pan to achieve maximum capacity; 2) You need to get past a layer of undesirable or weak soil; 3) soil erosion is a possibility and if 5 feet of soil is washed away, you don’t want only 5 feet of pile remaining; 4) you need an installation in area where height is restricted and you have to use a short pile; 5) you wish to extend the pile to a significant height above grade.

Postech Winnipeg has extensions available to ensure a solid foundation no matter the special circumstances facing your building project.  Extensions are very reasonably priced and available in 3 foot, 5 foot, 7 foot and 10 foot lengths and are typically bolted on to the initial pile.

Question:  How deep can Postech screw piles be installed?

Answer:  As deep as necessary.  Postech Winnipeg has installed piles as deep as 35 feet and other dealers have gone deeper than 60 feet.
