We just moved into a house that has water seepage in our basement. There's interior french drains and a sump pump there--neither of which are that great. Furthermore, the sloping of the land in our backyard does not allow for good drainage. Not only that, our yard's topography is such that run-off from adjoining yards feeds into ours. My wife & I want to do EXTERIOR FRENCH DRAINS around the perimeter of the house and criss-crossing through our yard. Do you think this is a good idea? Some people have told us (a) not to do this in the winter (because the tar doesn't stick well to the foundation in the cold) and (b) exterior french drains are "worthless" because eventually dirt clogs them up. Any truth to that? We really want to prevent ANY water from entering the house whatsover. Again, do you think exterior french drains will do the trick?
First of all I can tell you what procedures to follow in order to re direct water from your home and what the best products to use to water proof your foundation.I first need more info. what type of soil ? Do you know if you have a exterior weeping tile at edge of foundation footing? how old is the Home. How much of a slope to the house. One thing also you can do is check with your building division to see if the homes around you have the proper grades set. Most Citys and towns cannot allow water to be directed to any ones property. Also your Location
