I live in Tulsa, OK. I have a full basement under the house and would like to build some rooms into it. To do this, obviously, the leaking will have to be corrected.
As best I can tell, the basement leaks for one particular wall where a window is. The outside ground comes to the bottom of the window. Also, when there has been a lot of rain it will leak slightly through the many cracks in the floor throughout the basement.
I want to do the work myself and save the cost of having professionals do it. What is the best approach to seal off the leaking?
