We built a new house last year and it was completed in June. Ever since we’ve lived here I notice the basement block walls seem to look damp in areas, especially after a rain storm. I’m certain there is a tar barrier on the outside and footer drains as well as french drains tied to a sump crock. The sump pump runs maybe 2-3 times per hour for about 15 seconds on a regular day. We’ve never had any standing water even after days of the worse rain storms I’ve ever seen earlier this year.
My question is if his is normal or if I need to be contacting the builder about this issue? The block isn’t sealed inside and I plan to paint/seal it soon to begin finishing the basement but I want to make sure everything is correct before I proceed.
