There are many situations that may call for a French drain system….


If you have water penetration up from the bottom of your basement floor it is usually caused by a high-water table (rising water), hydro static pressure (water being pushed up by lack of soil drainage usually hard soil or clay), or if you have a cement block foundation (hollow walls that can fill with water).  An interior French drain system would be the remedy for you.  An interior French drain system consists of installing perforated drainage pipes below basement floor to catch water below the basement floor level and move water to a collecting point in your basement (sump pump canister) where it can be collected and pumped out to an optimal location.
