How should accessible gaps to perimeter channel drains and foundation drainage boards be managed?

Managing accessible gaps to perimeter channel drains and foundation drainage boards is crucial for maintaining effective drainage while preventing unwanted moisture intrusion. Gaps in these areas should be closed or sealed to ensure that water is directed appropriately without compromising drainage control. This means sealing the gaps in a way that allows for water to drain effectively while minimizing the risk of water pooling or entering the building foundation.

Sealing these gaps helps prevent debris, soil, and pests from entering the drainage system, which could clog it and reduce its effectiveness. Additionally, properly sealing the gaps ensures that moisture and vapor barriers are maintained, thus protecting the structural integrity of the building.

In contrast, leaving the gaps open for air circulation could allow rainfall or groundwater to enter, leading to potential water damage. Filling the gaps with soil might lead to blockages over time, and ignoring the gaps is not advisable since they play a significant role in the overall drainage system's performance. Therefore, the best management practice is to ensure that these gaps are properly sealed while maintaining effective water drainage control.
