So, after the latest storm, my tenants in the basement noticed some water in one of their bedrooms. I knew there was a crack visible from the outside, but it had never leaked until last week. I have called 'Alberta One Call' to do a service locate so I can excavate outside, to repair the crack. Does anybody have any experience doing this type of thing? Should fixing the outside be enough, or should I rip out the drywall and repair inside as well? Please, help point me in the right direction!
