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: High humidity level in basement. Corrective actions include the use of a dehumidifier, air condition 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 waterproof the exterior basement wall.
