a method called electro-osmotic pulse (EOP) is starting to be used for both new construction and repair work. Once the system is installed, it can be operated for the same cost as running a 50-W lightbulb and you can “waterproof” your basement walls. That's less than the cost to operate a sump pump.
Unless all necessary measures are taken, and thoroughly executed, the part of a building that is below grade will most likely be troubled from time to time with intruding water.
