What is a major cause of leaking foundations?

Improper drainage is a significant factor contributing to leaking foundations. When drainage systems are not functioning correctly, water can accumulate around the foundation. This can be due to several issues, such as blocked gutters, inadequate downspouts, or poorly designed grading that directs water toward the house. As water builds up in the soil surrounding the foundation, it creates hydrostatic pressure, which can lead to leaks, cracks, and even structural damage over time. Good drainage practices, such as ensuring proper slope away from the foundation and maintaining clear drainage paths, are essential to protect a foundation from water intrusion and maintain the integrity of the structure.

While poor construction, weather damage, and old materials can contribute to foundation issues, they do not directly cause leaks to the same extent as inadequate drainage, which addresses the underlying water management around the foundation. Proper drainage is crucial for avoiding water-related problems and maintaining a dry, stable foundation.
