Ground Seepage in Basement

When we bought our 4 1/2 years ago a Pioneer Basement System had recently been installed prior to the closing (there is also a Kenmore dehumidifier). Since then we have had a couple of minor incidents of seepage but we have stayed dry (including with heavy rainfall and record snow accumulation). Just this week our neighbor started excavation for an addition, about 15 feet from our home, and there was a rain storm that went through resulting in about an inch of water in the center portion of our basement. In this time we also noticed condensation over the pipes in the basement and a musty smell. The perimeter of the basement where the French drainage system is located is dry and the sump pump hasn�t been pumping much but is verified that it is in good working order and was recently serviced.

First we had a plumber out to verify that the pipe were ok then we had Pioneer out since there is a warranty on this system for no water in the basement. Pioneer stated that this was due to condensation that has built up under ground and with the cool temperatures that we have been having suddenly turning to warm it seeped up into the basement. He said that proof of that the condensation on the pipes. He recommended that we install a Santa Fe dehumidifier and that will resolve the issue. I mentioned if a channel should be through the center of the room in addition to the parameter and he said that it wasn�t necessary (the room is not to big). He felt that the excavation really had nothing to do with the seepage.

I do believe that we are in need of a new dehumidifier but a Santa Fe? Has anyone ever heard of this?

RE: Ground Seepage in Basement

You likely have two sources of water: condensation--which occurs when the warm moist summer air hits the cold pipes and walls in your basement and water from the saturated soil wicked up by hydrostatic pressure through the floor, footings and walls.

A powerful dehumidifier is the first line of defense. The Santa Fe, which is claimed to remove up to 110 pints of water a day, may be overkill for your situation. See link for calculating dehumidifer size.
