Help! I have a completely finished off basement...drywall, carpet, wood trim, the works. Recent heavy rain caused major leakage in several areas around the outer walls of my house. This year's spring rains was much worse than last. So I'm determined to get it fixed. However, I must rely on other people's advice and expertise since I have no knowledge on this subject. I am discovering there are many different solutions. How am I suppose to know which one is right for my home?
