It provides support for the weight of the entire structure and safeguards against soil erosion, structural damage, and moisture penetration. However, when the foundation is undermined by tree roots, it can lead to significant issues.

Types Of Trees That Can Cause Foundation Damage

The beauty of trees is undeniable. They provide shade, purify the air, and offer a sense of calm. However, not all trees are suitable for foundations, especially in areas where the soil is clayey. There are several types of trees with aggressive roots that can cause severe damage to foundations.

For instance, the silver maple has a shallow root system that can stretch 25 feet away from the trunk, causing it to compete with nearby structures for water. Another notorious tree is the weeping willow, with roots that can grow 3-4 times the height of the tree and spread up to 50 feet.
