ICF foundation worth the extra cost?
We are lifting our cabin/lake home and adding a walk out level so we can get more living space. The contractor is recommending we use an ICF foundation as it will allow the lower level to be more comfortable and not damp/musty. The extra expense is approximately $8000 more than a regular foundation. We know nothing about this system and came here to research this. The cabin will mainly be used in the spring/summer/fall with minor usage around the Christmas Holiday. Is the extra expense worth it???
