: A French Drain depends on the ground below the floor being able to absorb the moisture that accumulates. If the water table is high, then the drain will pobably not work, and if the table is high enough as I have seen it in some areas, it could be a source of flooding. Also the drain only removes the water after it is in the basement, so a finished room would be subjected to the water infiltration. The best, and much more expensive solution is to install a drain pipe around the outside of the residence, at a level lower than the finished floor, and connect it to a sump pump which would discharge the accumulation to a sewer or area remote from the house.: : Ive been told by some that this is the best way to go to keep my basement dry. The water table in my area is high, but this is the first time Ive had water in my basement since I bought the house brand new 4 years ago. How is the success rate with these French drains and what other options do I have. I would like to finish my basement in the next couple of years. Thank you for whatever advice you can give.
