How Not To Build a Retaining Wall
What happens here
The video issues a strong warning against planting trees too close to or on top of a retaining wall. While the static weight of a tree can theoretically be accounted for in a wall's design, the dynamic load and expansion of tree roots are unpredictable and cannot be engineered against. As tree roots grow and spread, they exert immense pressure on the retaining wall, inevitably leading to structural damage and wall failure. Bushes are acceptable near retaining walls, but trees should be avoided entirely to preserve the wall's integrity.
Goal: Prevent structural damage and failure caused by tree root growth.
