I have seen homes where I could put my entire hand through the hole that moisture rotted out.

What happens here
This project provides a comprehensive guide on how to address and prevent structural damage to a house caused by direct contact between patio base materials and non-concrete components of the home. The video demonstrates the critical issue of wood rot resulting from moisture retention when gravel or similar materials are improperly placed against siding or sill plates. The DIY steps include identifying existing damage, carefully excavating the problematic fill, repairing or replacing any compromised wood elements, constructing a durable concrete or masonry barrier to ensure proper separation, and finally, backfilling with new base material to restore the patio with appropriate drainage, safeguarding the house against future moisture-related issues.
