Basement moisture problems can range from the basement becoming a bit musty in the summer to wetness or dampness in the winter.
1) Mustiness: problem of minor condensation caused by cool underground concrete walls reacting with warm humid air from outside or upstairs in the home. It can be corrected using a dehumidifier to remove water vapor from the air.
2) Wall Condensation: hHigh humidity level in basement. Corrective actions are the use of a dehumidifier, air conditioning the basement, and insulating basement walls and use of a vapor barrier.
3) Seeping Water: visible dampness on floor near wall or on wall near floor, which is most noticeable after a heavy rain. Minor wall dampness may be solved by an oil based masonry waterproofing paint.
4) Water Leakage: visible water trail from crack or hole in basement wall. Small hole may be plugged with a hydrostatic cement. Repair large cracks by digging down from outside and repairing crack with hydraulic cement and then waterproofing the exterior basement wall.
