Building a cottage with a walkout basement.
The cottage will not be heated.
I installed a frost wall at the front and back 12' on each side. The back and sides are backfilled 6' over the footings on the outside. The floor is 4" concrete and drainage is installed outside at footings.
Also I installed 2" of styrofoam in from the footing horizontally for 24" under the floor.
Will I have a heaving problem next spring?
We built in Haliburton Ontario.
