How do I protect the ICFs below grade?

All ICF walls below grade, that have hab­it­able space on one side (base­ment), must have a water­proof­ing / damp­proof­ing mem­brane installed. For walls that do not have hab­it­able space on one side (crawl space, frost walls, etc.) the EPS can be left exposed to the earth. The EPS will not dete­ri­o­rate when exposed to the earth.
