Dehumidifiers | TerraFirma Basement Waterproofing Systems


Even a basement with an effective waterproofing system can still develop moisture, and mold problems and may feel damp. Our latest generation SaniDry™ dehumidifiers circulate dry air throughout the space, aggressively drying out your basement or crawl space. Collected water can be drained into a sump pump pit, a section of your perimeter drain, or away via a condensate pump.
