Is this a variation of foundations I have seen in passive house design were there is a horizontal insulation and over that reinforced concrete slab 30cm thick (without that deeper sections below external walls) ?
Awesome vid, first one I have seen done specifically for Canada (I imagine that's where you're located). I saw the pdf on the government of Canada website and searched for this foundation. Is it recommendable to do this at lake front lots? Or would piles or even screw piles be better due do a potentially high water table. In Alberta to be specific, where most lakes are slews in a field lol so we rarely have a rocky shore
Thanks so much for watching! I'm actually located in Oregon, but I'm familiar with cold climate building techniques. Great question - I would avoid any slab foundation near lake fronts unless you're significantly above the lake level. All it takes is a rainy season to potentially flood your home. Pier foundations are best in these situations, especially in the case of a high water table, as any flooding events are less likely to cause water damage.
thanks a lot! I have been binge watching the other videos, can you do one on pier foundations or screw piles and how to best insulate and keep out bugs on the underside? I love the look of that on flat roof houses instead of a crawl space @@ASIRIDesigns
Why do you consider it important to have continuous insulation under the slab? That just reduces the heat from the building that is helping warm the soil beneath and then increasing the size of the insulation skirt needed to protect the foundation.

Does this apply if the building was say a shed or garage in Maine that is not going to be heated or cooled?
Thinking about using an SPSF for an off grid cabin, I don’t want to dig past the frost line nor do I want a basement. Seems like a good solution.

What is the reason behind gravel under the XPS plates that are NOT under the building? Reduced capillary suction or other? Can it just be groud?
Guessing additional drainage to make the rigid insulation last longer
Does anyone know why the rigid insulation is not OVER the vapour barrier?
This is to prevent the rigid insulation from floating if concrete gets between the cracks. It should drain well enough with the gravel below
@@Austin-fc5gs Makes sense! Thanks
