ICFs are made of hard plastic foam that provides insulation. The forms lock together, and concrete is poured into the space between them. They’re strengthened with steel bars.
ICFs aren’t a food source for insects. However, insects can burrow into them to reach wood that is. Also, water can get trapped behind the forms and cause hard-to-detect problems.

Step 1: Begin inside your home. Check for cracks in the walls, slanted floors, and windows or doors that don’t open properly. These issues could be signs of a shifting foundation.
Step 2: Look for standing water around your home or in your basement. That could indicate a drainage problem. Staining on the forms could mean water is trapped behind them. If you notice staining or standing water that doesn’t drain in a few days, contact a pro.
Step 3: Check for any forms that look out of place, cracked, or crooked. These could be signs of foundation movement. If you notice these problems, get a professional inspection.
Step 4: Remove anything growing on your foundation. Moss, lichen, mold, and vines can damage ICFs.
Step 5: Check for signs of termites, including living or dead termites, damaged wood inside or outside of your home, or small mounds of sawdust. If you find these signs, get a professional inspection. Either way, protect your ICF by getting a termite inspection every couple of years.
