This shrinking or “condensing” of the air volume leads to greater humidity. Everything permeable in your basement will take in the additional wetness in the air and trigger a foul odor. Dehumidifiers are appliances which mechanically remove the undesirable additional humidity from your basement. An excellent dehumidifier is a should if you intend on redesigning your basement. Even a basement that does not leak will gain from utilizing a dehumidifier.

Water Leakage

. After you exhaust all preventative measures outside, try to identify areas inside where you are experiencing the leakage. If a corner of the basement seems to be a particular issue, again, look outside at your rain gutter downspouts. If you see fractures in the walls leaking, a few of these can be fixed with hydraulic cement or fracture injection. If water seems to be can be found in from an isolated area, installing a sump pump below floor level can reduce the water level and underground hydrostatic pressure in that area. If you are not sure or your issues appear to be prevalent, it may be best to call in a building inspector, engineer or other professional to assist you identify and solve your issue. There are a range of services available to solve your leakage issues. These consist of; outside excavating, re-parging your walls, interior or outside drainage systems, interior cove systems, grout or epoxy injection and others.
