I need some advice on the topic of French Drains. I have water seepage on one wall in the basement from ground water. I have heard many pros and cons of installing an interior french drain. Of course, the best solution is to install an exterior drain, but the cost would be tremendous given the patios, landscaping and other obstacles around my house. I do not even have a sump pump in my basement. Do these interior french drains work? Is it worth my time of installing one and finding out later that it does not work? I appreciate your response.
