I live in an old brick house (1913) in southern Michigan that has a stone walled basement. The walls have been parged and we have a cement floor. This is our 1st home and we are true novices when it comes to things such as waterproofing & french drains. The situation is that on the north side of our home we experience leaking in our basement after heavy rains, mainly on the north side. We have had our gutters cleaned and spouts are directed away from the house. The ground seems to be always moist on this side and doesn't get much sun. We do have a central air system on this side also. We were advised to "improve the grading" and possibly add a sort of modified french drain. We really don't have much of a yard to work with as our property fence is approx. 25-30' from the house. Any suggestions/directions in terms we can understand would be greatly appreciated.
