There are really only two options available to solve wet basement problems in southeast Michigan: interior or exterior. Interior work utilizes drainage inside your basement to control the water that is entering and directs it to a sump pump.
This method should never be called waterproofing, it should be referred to as water control. Water control systems allow the water in, in order to pump it back out. True basement waterproofing in southeast Michigan is accomplished only by exterior excavation to the bottom of the foundation, installing proper drainage and treating the walls to prevent water from entering. Let it in and pump it out, or keep it out altogether. This is the main difference between waterproofing and water control for your basement.
