My finished basement gets water in it during heavy rain, not always but maybe once or twice a year. We can go a year with no leaks, we have an outside sump pump that does not always work. Can you tell me your options for waterproofing my basement, including methods that do not require drilling into the concrete floor and drywall. Also can you let me know if I need an updated sump pump. Let a message if you call and do not get an answer.
