I have been reading alot about Frost Protected Shallow foundations and have a few questions I was hoping someoen could halp out with.  I am in an part of canada that calls for at least 4 feet frost coverage more in some areas and have heard about this method of building.  I have several crwls spaces and walkout basement houses lined up and was considering using this method.  Is this a viable alternative to using piles or would I still need piles to keep a shallow dig?  Is this dependant on soil conditions any more than a normal footing? I would like some more feed back from people who use this method as to its effectiveness.
Thanks

I have done the shallow footing and insulated out from the foundation as required. Honestly I did not like it since the footing was only 12" below finished grade 4" foam was placed on toip of that and extended 4' out from the foundation wall, fill was placed back on top. What I didn't like was how the landscape would be done with the foam so close to the horizontal surface.

My attitude is if you can dig it, dig it right.
