I personally know of two homes with wooden basements where the walls heaved up to 4" from thier original position in the 25 years since they were built.Both owners ended up building a sub basement inside of the original basement to correct the problem.I should add that the homes are located in an area where the homes were built on what used to be muskeg,and we get a great deal of frost.However,the concrete basements are holding up fine in the same area.After seeing those homes,I will never consider a wooden basement.
