Major Causes of Basement Problems
Hydrostatic pressure exerted against the foundation of your home can cause cracks, bowing, and even collapse in severe cases in basement walls. Hydrostatic pressure exerted against the foundation of your home can cause floors to crack. Initially, water may only rest in the block or in the pores of the concrete but over time the seeping water causes leaks and dampness.
Settlement around your walls can cause your foundation to move and shift. This shifting can cause cracks that allow water to flow into your basement.
Capillary Attraction (wicking):
An example of wicking (water contact) can be identified when a block may not leak, but feel damp. Whenever a porous surface like concrete blocks or basement floor comes in contact with water, it soaks water up like a sponge. Continuous hydrostatic pressure exerted against the foundation of your home causes walls and floors to store water like a reservoir.
The land around your home may have low spots or pitch so the water flows toward your home.
High Water Table:
Rain, melting snow, under ground springs, can contribute to the water table rising around your home. This can build up pressure against walls and beneath the floor creating a damp or wet basement.
