Default re

you would be surprised at how little effort it takes to heave a footing due to frost, plus that method is only as good as the ground on which it rests. If at all possible drill piles, size to be negotiated with your building and imposed loads. If your just using treated 6x6 they should be fine for years, try to slope the surrounding ground away from the building although, unless of course your using an internal sump (i doubt because its a cabin), personally i wouldnt laminate treated 2x6 together they will hold together untill the bond between them either rots away (nails) or seperate due to expansion /contraction which is ineveitable especially in high humidy areas like that. You can purchase the treating compound and always give the 6x6 another coat or 2, especially on the ends, and dont be afraid to reapply it whenever you want .
