Hey Manitobans, do you ever wonder why the piles you build your home on aren’t protecting you from movement due to frost heaving?
The reason is that Manitoba’s extreme weather, -45 in the winter and + 35 in the summer, causes ground movement due to frost heaving. This ground movement packs some serious force and is capable of displacing a lot of weight.
In Winnipeg, where homes are built mostly on clay soils, building structures may even see movement due to clay drying in the summer. Winnipeg, really is a tough place to build solid and stable structures!
Have you ever pounded a nail into wood and at the same time screwed in screw into wood? Which of the two were easiest to pull out using your hammer? It is for the same reason that the nail is easiest to pull out that the traditional concrete piers or driven steel piles sometimes don’t require much to heave or sink.
The solution is to find a piling system that acts the same way a screw does in wood but in the ground… screw piles. Screw Piles are made up of a steel shaft and a helical blade angled for screwing. As long as the helical is installed below the frost line, screw piles are extremely effective against heaving. The reason is that they are anchored below moving soil providing serious holding power to combat the friction on the pile above the frost line.
