A Comparison of Postech Thermal Piles VS Ground Anchors VS Concrete

“Oh you have pretty much have a Groundhog anchor right?”  That is a question I get all the time here in Winnipeg. My standard answer is, “Yes and no, I would say we are in a completely different league.”  Little league tykes baseball and adult professional baseball are both classified the same sport but there is a significant performance difference between the two.

Fortunately smaller ground anchors have been available in Winnipeg since the mid 90’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.

In some circumstances installers of smaller ground anchors have failed to install piles which can hold the required loads or that are not long enough to anchor below the frost line and many decks, home additions and sunrooms have lifted, sunk or shifted on the systems which have existed until recently in Winnipeg and throughout Manitoba.

Either way both the Postech and smaller ground anchors have some distinct advantages over traditional concrete piers.  Below is a chart which explores and compares each piling system:

Cost for deck pile

$375 for 10’ galvanized Thermal Pile with 2.38” shaft and 12” helical (laser leveled and including pile marking)

$280+ for 8’ painted Groundhog with 2” shaft and 12” helical (installed to grade)

$500 or more – may not include removal of tailings or repair of damaged landscaping

Each piling system has it’s merits and no one piling system will be right choice 100% of the time; however there is very little a Postech Thermal Pile can’t do that concrete alternatives can.

Aside from rare circumstances where a location can’t provide a 28″ wide access point, there is really nothing a Postech Thermal Pile can’t do that a smaller ground anchor can.  You should also not that our hot-dip galvanized piles last more than 2.67 times longer than untreated, painted steel offered by competitors.
