To pour concrete or to not pour concrete?
Now, back to the the main focus of this article: To pour concrete or not to pour concrete? That was the question! The foundation plan called for concrete filled sonotube for the posts to rest on. Before we started excavation I had visited the Canadian Home Builders Association Home Show (http://chbanl.ca/event/34th-annual-home-show/). It is a one stop shop for everything related to home building. As I walked in the GoliathTech booth was one of the first booths that caught my eye (http://www.goliathtechpiles.com/). These are basically a ground screw: A long steel shaft with a helical thread that can be used to bore into the ground. I hand off my plans to Ken Duff (our local representative) and within a day or so their calculations came back with specifications on the screw piles to be used for this application. After several delays on my side the appointment was schedule and Ken pulled up in a shiny black GoliathTech truck (Photo 3-1). Ken was a pleasure to work with and is very accomodating. He is patient and works methodically to slowly let the helical pile do its work. As it twists through the ground it cracks and pops and twists some more. Some times it diverges and Ken works to bring the pile back on target. Rocks in the ground do pose some problems but there are work arounds. Once they are bored into the ground they are cut and toped with a threaded connector that has a variety of top plates meant for centering posts. There is some flexibility with centering. There will be more on this at a later date ie once we start framing the timber entry). The nice thing about these piles is that they also provide uplift protection as specified in the 2015 National Building Code of Canada. In a windy location like Flatrock...this could come in handy!
