This has been an on/off winter, warm one day - freezing temperatures the next. When water falls and then freezes over and over eventually it gets in to existing cracks in the (basement foundation) .It then freezes and expands causing a separation in the wall of the foundation allowing (water) to seep in and cause basement leaks and damage needing repairs. That is where waterproofing contractors come in. Another culprit is those weeping tiles getting old and plugged with sand and dirt . .Once that happens their is no where for the excess water to go except into your basement causing more headaches and damage to your residential home.
