Flex Seal is a rubberized sealant for leaks and can seep deep into holes and cracks.
There are many Flex Seal Reviews all over the internet. I read a review where a customer used it to seal foundation cracks and after they used it, the water stopped leaking in. Other customers have mentioned how easy the product is to use.
