What is the general purpose of waterproofing foundation walls?

The primary purpose of waterproofing foundation walls is to prevent water intrusion. This is crucial because excess moisture can lead to a variety of serious issues, such as structural damage, mold and mildew growth, and a decrease in indoor air quality. Waterproofing helps create a barrier that keeps water away from the foundation, ensuring that the integrity of the building is maintained and that living spaces remain dry and safe.

While movement of the foundation, temperature control, and aesthetics are important considerations in construction, they do not directly relate to the core function of waterproofing. Preventing water intrusion is essential in maintaining the longevity and stability of a structure, making it the most relevant choice in this context.
