What may contribute to my basement waterproofing and/or mold problem?

Frequently, wet basements occur in homes that lie in low-level areas at the bottoms of slopes or hills, but the everyday shifting or settling of your home may also cause leakage. Other potential causes may be poorly-mixed foundation concrete or improperly designed drainage systems. Tree roots may also grow into the weeping tile system and block water flow. Finally, weather can be a factor.
