There are numerous common causes of moisture or water infiltration. Naturally occurring hydrostatic and lateral pressure can often force water into the basement against the foundation walls or underneath the footings, causing damage and creating leaks. Heavy rainfall or melting snow may cause the water table to rise, which will increase the pressure. Soil composition can affect the drainage; loam and sand drain efficiently, while clay absorbs water and drains slowly.
Getting a drain tile or a French drain installation can redirect groundwater away from your home’s foundation to alleviate pressure. Unfortunately, drainage systems that are clogged, broken, improperly installed, or deteriorated can also backup and cause basement flooding. Poorly maintained window wells and windows can also allow moisture seepage. Caulking and weather-stripping around the window frame may be missing or deteriorated. Window wells can collect water if debris blocks the drain and may overflow into your basement.
