I am planning on building a small cabin this spring on the Kenai Peninsula, after I haul in all of the building materials over the winter. However I am undecided on how I am going to make the foundation. Any ideas from those guys with experince with this sort of thing? What has worked for you in the past?
Thanks in advance,
Plan on building 12x16 cabin.
No Perma Frost.
Wet soils... closer to silt/mud than sand.... seems to be bottomless, to at least to 4' down. Test post holes started to fill with water after a few minutes, level of water was about 18 inches below surface(???).
I am leaning towards:
Sinking pressure treated posts down about four feet. Wrapping with plastic to prevent heaving. Backfilling with what I dug out of the hole. Deal with settling as it occurs.
Haul in premix concrete. Use sono tubes. Back fill with what came out of the hole.
I have heard of this:
Digging a hole 24" square to a depth of 16". Back fill with gravel/crushed rock. Lay down concrete pavers and place pyramid shaped concrete block on top of pavers. Not sure if this will heave???
I would like to stay away from #2 & #3 because I have to carry every thing 300 yards. I don't think I can get up the bank with snowmachine, hope to find out when we get some snow.
