These types of foundations may have voids or spaces that can harbor pests, moisture, or other detrimental factors that can compromise the integrity of the foundation and the overall structure. Extreme caution in treating the exterior soil and voids is essential to ensure that any treatments used penetrate effectively and eliminate potential pests or moisture issues without causing harm to the foundation materials.

Ensuring that the treatment is applied correctly protects both the foundation material and the structural health of the building itself.
