Frostline
#1

I am building a new home. I live in Ontario where we get some pretty cold winters. Sometimes the frost reaches 6' into the ground and that's close to where the watertable or waterline is. How do you determine how far down for the footings?
Also, have you heard of whiteblock, if so what's your opinion on it?

If you have local building code authorities, check with them regarding requirements.
