What is considered more effective than sealing moisture out of the foundation?

Diverting moisture with a drainage system is considered more effective than merely sealing moisture out of the foundation because it addresses the root cause of moisture intrusion rather than just blocking it. A drainage system helps manage and redirect excess water away from the foundation, significantly reducing the chances of water accumulation that leads to problems like mold growth, structural damage, and foundation settling.

In contrast, sealing methods such as sealing cracks or laying additional waterproofing material only act as barriers. While these methods can be beneficial, they do not proactively manage the water that may accumulate around the foundation due to poor drainage or flooding conditions. Similarly, installing a sump pump is a reactive measure that can help pump out water that has already accumulated but does not prevent water from entering the area in the first place. Effective drainage management focuses on redirecting moisture before it can interact with the foundation, making it a more comprehensive solution for long-term moisture control.
