This is exposed basement insulation that had been damaged by years of sun exposure. Once the paint started failing, UV slowly destroyed the spray foam. It became brittle, started falling apart, and left holes where water, insects, and small animals could get in.
We removed the damaged foam completely, including slightly below the gravel level, and replaced it with rigid foam board. The bottom and joints were sealed with spray foam so the new insulation connects with the existing insulation below grade. Then we painted the exposed surface to protect it from UV.
There is another reason not to simply remove this insulation and leave the concrete exposed. The insulation helps keep the inside surface of the basement wall warmer. In winter, if that surface gets cold enough to fall below the dew point of the indoor air, moisture can condense on it. That’s one of the reasons continuous insulation around a basement foundation matters.
You can absolutely do this repair yourself. The important part is not just making it look better. Remove all loose and damaged foam, continue the repair slightly below grade, seal the gaps between old and new insulation, and protect any exposed foam from sunlight with a compatible coating or finish.
Or, of course, we can do it for you.
