"So, what's the difference between your VersaPile Screw Piles, and a Groundhog anchor from Home Depot?"
That's a question I get all the time here in Winnipeg, and it's a good one! People want to know what the difference is between our VersaPile Screw Piles, and those ground screw anchors you can buy at most building supply stores.
My standard answer is, "VersaPile Screw Piles and ground screw anchors are the same idea, but in two completely different leagues." For instance, little league baseball and adult professional baseball are technically the same sport, but there is a significant performance difference between the two.
Ground screw anchors have been available in Winnipeg since the mid 1990's, and have brought recognition to the concept of screw piles in Winnipeg. Unfortunately, they have also instilled a very narrow idea of what helical screw piles can be effectively used for. Many people still think that screw piles are only good for small decks or patios, and never realize that screw piles can be installed under large structures like new homes, and even commercial projects like greenhouses.
A Typical Ground Screw Anchor That Can Be Found at Building Centers
Sadly, there were cases when installers of smaller ground anchors failed to install piles that can hold the required loads. Or, they installed piles that weren't long enough to anchor below the frost line. This led to decks, home additions, and sunrooms sinking and shifting on the "screw piles" systems that have existed until recently in Winnipeg and throughout Manitoba.
This has also led to confusion about which system - VersaPile Screw Piles, Ground Anchors, or Concrete Piles - is considered the "best".
That's a trick question. Truth is, there is no one foundation that does it all. However, there are significant differences between VersaPile Screw Piles, ground anchors, and concrete piles. The easiest way to see these differences is to stack the foundations up against each other and see how they come out.
Screw Piles Were a Great Fit For This Porch, Due to The Difficult Install Location

When the data is laid out like this, you can see that each piling system has it's merits - but no single foundation will be right choice 100% of the time.
However, there is very little a VersaPile Screw Pile can't do that the other alternatives can.
The advantages to a VersaPile Screw Pile are significantly greater weight capacities, anchoring below the frost line, and laser-leveled installs (to name a few). Our hot-dip galvanized piles also last more than 2.67 times longer than untreated, painted steel which means decades of firm support with no corrosion.
I'm not saying that you should always use VersaPile Screw Piles, full stop. Every situation is unique, and your requirements could be different.
The fastest way to see which foundation is right for you would be to ask our friendly foundation experts. We can help you figure out if a VersaPile Screw Pile foundation is a good choice for your project. If you want a free estimate, contact your VersaPile professional by clicking here.
