Technological advances in the last 15 years now allow most modern basements to be made into comfortable, livable space. However, all basements are vulnerable to some water penetration during their lifespans.
Drainage tile, damp-proofing, and moisture barriers all assist in preventing moisture from entering the structure through the foundation walls. Even with all these in place, if the area experiences an unusually high level of precipitation and the ground becomes saturated with water, the tile system may not be able to handle the volume and the hydrostatic pressure that builds up along the foundation wall may force some of the water through hairline cracks and/or pores in the foundation walls. Older homes that may not have the advantages of modern technology and those that have more porous types of foundations (block, brick, stone) may be even more vulnerable.
